Location Memory cannot be used by the WSD-F10.

GPS

Q1What is the accuracy of the GPS location information?
It depends on your current location. Depending on reception conditions, GPS positioning information may include error up to several hundred meters. Because of this, you should never use the GPS function for the applications below.
• For surveying or any other measuring that requires high accuracy
• For navigation of boats, aircraft, motor vehicles, individuals, etc.
• In addition, GPS location information should never be used for any application in which its accuracy could present a risk to human life.
Q2Can GPS be used anywhere for positioning?
Your current location greatly influences your ability to obtain GPS information. You may experience GPS signal reception problems in the areas like the ones described below. In extreme conditions, you may not be able to receive GPS signals at all.
• Where the view of the sky above is narrow or where there is no view of the sky above
• Near trees or buildings
• Near a train station, airport, or other congested locations, or in locations where there is heavy traffic and radio wave interference
• Near railway aerial wires, high-voltage lines, TV towers, etc.
• Underground, in a tunnel, or underwater
• Indoors (Reception may be possible near a window.)
• Near wireless communication equipment or other devices that generate electromagnetic waves.

GPS satellites are in constant motion, so your location, the time of day, or other factors may cause a delay in the positioning operation or may even make positioning impossible.
Q3Is the GPS function of the watch always running?
When the watch is close enough to its paired phone to communicate with it, it will use the phone's location information. The watch's built-in GPS is used when the phone's location information is turned off or when the watch is unable to communicate with the phone.
Note that the WSD-F10 does not have GPS built in.
Q4Is time calibration by GPS supported?
Yes. However, the calibration operation is manual and regular automatic calibration is not performed. GPS information is acquired for your current location and the time is calibrated only when manual calibration is performed. After that, the time setting will gradually become out of sync. You will need to perform manual calibration as required.
Note that GPS time calibration is not necessary if you use the watch in a way that it normally communicates with a phone because the watch will automatically calibrate its time setting with that of the phone.

GPS Time Calibration Procedure
1. Select any CASIO watch face.
2. Go to the setting screen of the selected watch face.
3. On the list of settings, select "GPS Time Calibration" and then follow the instructions that appear on the screen.
● Not supported by the WSD-F10.
Q5Does GPS time calibration work even in the Timepiece Mode?
Yes. In the Timepiece Mode, GPS time calibration is performed automatically, and no manual operation is required. Note, however, that GPS time calibration is performed regularly only when you are outdoors in an open area where the sky is visible, where satellite signal reception is good. It is not performed if you spend long periods indoors where satellite signals cannot reach.
● Not supported by the WSD-F10.

Q12Why are their gaps in the altitude and barometric pressure graphs, and why aren't displayed number of step and calories burned values correct?
Altitude, barometric pressure, number of steps, and other readings are not performed while the watch is turned off or while it is in the Timepiece Mode. Because of this, no data is shown in graphs or incorporated into displayed values during such periods.
Also, lack of connection between the watch and phone for a long period will also cause gaps in graphs and incorrect measurement values.
Q13What should I do if the inside of the glass becomes fogged?
The inside surface of the glass may fog when the watch is exposed to a sudden drop in temperature. No problem is indicated if the fogging clears up relatively quickly.
Sudden and extreme temperature changes (such as coming into an air conditioned room in the summer and standing close to an air conditioner outlet, or leaving a heated room in the winter and allowing the watch to come into contact with snow) can cause it to take longer for glass fogging to clear up.
If glass fogging does not clear up or if you notice moisture inside of the glass, immediately stop using the watch and contact your original retailer or to an authorized CASIO service center.
Q14What is there to know about the liquid crystal panel of the watch?
The liquid crystal panel on this watch uses high-precision technology that provides a pixel yield in excess of 99.99%. This means that some very small number of pixels may not light or may remain lit at all times. This is due to the characteristics of the liquid crystal panel, and does not indicate malfunction.

Location Info Access
Location info used to detect when you approach or move away from a specified location.

Activity

Q1What does the Activity app do?
You can display your current progress while you are engaged in one of the activities below.
• Climbing or trekking
• Fishing
• Cycling
• Kayaking and other paddle sports
• Snow sports (skiing, snowboarding)

You can configure the watch so, after you start an activity, it will display altitude, distance, speed, your route on a map and other information. You can also configure the watch to provide alerts that apply specifically to the activity you are currently engaged in. (MOMENT SETTER)

Paddle sports and snow sports are not supported by the WSD-F10.
Q2During trekking activity measurements, why is the speed shown by the watch different from my actual vertical speed?
Vertical speed values are calculated using altitude values that are converted from barometric pressure readings by the pressure sensor. This means that barometric pressure changes due to weather conditions can result in readings that are different from the actual altitude.

● This function is not supported by iPhone (iOS).
Q3During trekking activity measurements, why is my vertical speed shown as 0m/h (0ft/h)?
The watch performs a measurement startup routine during the first five minutes after starting the activity. At that time the vertical speed will be shown as 0m/h (0ft/h).

● This function is not supported by iPhone (iOS).
Q4During cycling activity measurement, why isn't my speed displayed correctly?
Speed calculations are performed using the GPS function, so calculation results may not be exact. Or the displayed values may be a number of seconds old due to communication timing. Note that screen refreshing is delayed when the display is dark. • This function is not supported when using an iPhone (iOS).
Q5During cycling activity measurement, why isn't my distance traveled displayed correctly?
Speed calculations are performed using phone GPS measurements, which may result in calculation errors. Or the displayed values may be a number of seconds old due to communication timing with the phone. Also note that the display refresh interval is longer while the screen is dark.

● This function is not supported by iPhone (iOS).

Tool App

Q1What does the Tool app do?
The Tool app is a built-in app by CASIO.
It has the following functions: compass, altimeter, barometer, sunrise and sunset times, Tide Graph, Fishing Time, and Activity Graph.
Q2Why doesn't the Activity Graph display properly? Why does it show me riding in an automobile when I am not?
The activity shown by the Activity Graph is based on data being picked up by various sensors. An activity that is difficult to detect by the sensors, short activity duration, and other factors can cause the watch to come to a wrong conclusion about your current activity.
Q3Why is the calories burned value shown by the Activity Graph different from by the actual number of calories burned?
For the watch to be able to perform calories burned calculation, you must use the CASIO MOMENT SETTER+ phone app “Profile Settings" to input your current body weight. The Activity Graph determines your activity by your arm movement and other factors, and calculates calories burned accordingly. If you are engaged in an activity that is difficult to detect by the sensors, the watch may come to a wrong conclusion about the type of activity you are currently engaged in. If that happens, the calories burned values it calculates may not be exact. Even if the watch is able to determine your activity correctly, calculations are performed using generally acceptable coefficients, which may result in calculation values that are different from those actually being produced.
Q4Why can't I catch any fish during the indicated fishing times?
Fishing time calculations are performed by determining the Moon's hour angle and age, based on the GPS longitude. Of course, there are other natural factors that affect fish behavior, so there is no guarantee that you will be able to catch fish during the indicated fishing times.
• With the WSD-F10, the watch will not be able to perform calculations correctly if there is no communication with the phone, because it cannot obtain GPS values.
Q5Why are the low tide time and tide level, and the high tide time and tide level I find in a newspaper or on the web different from those indicated by the watch?
Actual tidal phenomena fluctuate in accordance with weather, the season, and various other factors, and may give rise to irregularities not in accordance with calculated values. Certain conditions may result in actual tides being different from calculated data.
Because of this, the information produced by the Tide Graph function of this app and watch should be treated as approximate reference information only. Never use this information for any decisions about tide that may put safety at risk. For navigation purposes, be sure to use official tide charts for the area you are navigating.
Q6Why don't the sunrise and sunset times of the watch match actual times?
Sunrise and sunset time calculations are related to atmospheric refraction, which changes day by day. There is no way for calculations to take daily changes in the atmosphere into consideration. Also, calculations cannot factor in local topographic conditions, which also affect sunrise and sunset times. Finally, though calculations use longitude, latitude, and altitude data, such data provided by the GPS is not high precision, which affects calculation results.
Q7Why are the sunrise and sunset times I find in a newspaper or on the web different from those indicated by the watch?
The sunrise and sunset times calculated by the watch are based on GPS latitude and longitude of your current location, and so they may not exactly match the times for the location used for determining the times shown in a newspaper or website. Also note that calculations always assume a level horizon, and local topography is not taken into consideration. Calculation results include error, which increases at higher latitudes.

● If there is no communication with the phone, the watch will not be able to perform calculations correctly because it cannot obtain GPS values.
Q8Why is the altitude displayed by the watch different from the actual altitude?
The watch's altimeter calculates and displays relative altitude based on barometric pressure readings measured by its pressure sensor.
Because of this, readings taken at different times at the same location may produce different altitude values due to changes in air temperature, humidity, barometric pressure, and other factors.
Also note that values displayed by the watch may be different from elevations indicated for areas where you are located.
When using the watch's altimeter while mountain climbing or engaged in similar activities, you need to be sure to perform regular calibration in accordance with the local altitude (elevation) indications.
Also note that values displayed by the watch may be different from elevations indicated for areas where you are located in the case below.

・ During unstable atmospheric conditions
・ During sudden temperature changes
・ After the watch has been subjected to strong impact
Q9Why aren't altitude readings correct even though I am using "Calibrate for current location"?
"Calibrate for current location" corrects altitude based on GPS information. Though it automatically calibrates altitude readings, GPS measurement values are used as-is (without any correction), so the calibrated result may not necessarily match actual altitude or elevation above sea level. Such factors as the geoid elevation effect may result in errors in calibrated altitude readings.
For more accurate altitude readings, remove the check mark from "Calibrate for current location" and manually calibrate altitude readings at frequent intervals. With the WSD-F10, GPS information measured by a phone is used.
Q10Why does the barometric pressure graph indicate sudden changes or have missing segments?
• The graph may indicate a large jump when you change altitudes by moving to another location, or when there is a large fluctuation in barometric pressure due to sudden change in weather or temperature.
• A barometric pressure value is saved every hour.
Q11Why are direction readings incorrect?
What does it mean when a clock figure appears on the watch display when I try to take a compass reading?
Compass readings and compass calibration will not be possible if the watch is in the vicinity of a permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or electrical appliances (TV, computer, cellphone, etc.)
Also, magnetization guidance may appear on the display after the charger cable is connected to the watch, or in a location where there is strong magnetism. If it does, move your arm around so the face of the watch randomly points forward, back, up, down, left, and right a number of times until the guidance disappears from the display. For serious mountain climbing and other activities that require accurate bearing readings, take along a highly reliable compass to use in combination with the watch's compass.
Q12Can I specify a port or point for the Tide Graph?
Yes. You can select a Tide Graph point using the Tool app.

Selecting a Tide Graph Point
1. Swipe the touch screen from right to left several times
2. When the Settings screen is displayed, tap the gear, tap "Port setting" and then specify the point you want.
Q13How are tide levels calculated?
For Japan area oceans, tide times and level changes are predictively calculated using harmonic constant data obtained from Bibliography 742 Tidal Harmonic Constants Tables, Japanese Coast (February 1992) published by the Hydrographic Department of the Japan Coast Guard, and from the List of Tidal Stations (2015) published by the Japan Meteorological Agency. For other area oceans, tide times and level changes are predictively calculated using harmonic constant data obtained from NOAA, NOAA CO-OPS, and the NOAA Tides & Currents website, and the U.S. DEPARTMENT OF COMMERCE / COAST AND GEODETIC SURVEY January 1942 TH-1.

Watch Faces

Q1Can watch faces be added?
Yes.

For details about operations, refer to Android Wear Help.

Q2How can I change the World Time City?
World Time lets you select a city as your Home City (the city where you normally live).

(1) While the World Time watch face is displayed, press and hold it to display the settings screen.
(2) Tap "Home City" and then tap the city you want to select.
Q3Why does a watch face dial appear totally black without displaying anything?
Display of the phone battery level requires information from your phone, so the dial displaying it may go blank if communication with the phone is not possible. Also note that the CASIO MOMENT SETTER+ phone app must be installed on your phone to support this capability.
A compass dial will become blank if the watch has been exposed to strong magnetism. Calories burned information will not be displayed unless the "Save daily activity records" setting is enabled.

● Use of the CASIO MOMENT SETTER+ phone app is not supported with an iPhone.
Q4Why does "----" appear in a dial in place of an altimeter or barometric pressure value?
"----" may appear in place of the altitude or barometric pressure value in rare case that the current circumstances are interfering with proper pressure sensor operation. If this happens, wait for a while and then try again. If "----" remains on the display for a long time, it could indicate sensor malfunction. Contact a CASIO service center.
Q5Why are there missing segments in the altitude graph?
Missing segments in a graph are caused when altitude and/or barometric pressure readings could not be recorded because the watch was turned off due to a low battery power or some other reason. Note that this can also happen when pressure sensor measurement is interrupted due to a temporary system abnormality.
Q6Why can't I exit the monochrome digital watch face on the screen?
The watch may be in the Timepiece Mode. Hold down the watch's power button for about two seconds to exit the Timepiece Mode.
Q7My smart watch shows a monochrome watch face screen. Buttons and the touch panel don't work. What's wrong?
It probably means that Android Wear has been disabled because your smart watch battery is low. Your smart watch is designed to switch to a monochrome watch face automatically and maintain timekeeping functions only after its battery charge drops below a certain level. This is indicated by two horizontal lines (one under the date, and one under the hours and minutes).
Try connecting the charger cable and charging the watch.
Q8The monochrome watch face is displayed even though I selected OFF for the "Always-on Screen" setting. What's wrong?
The smart watch does not go entirely blank even when OFF is selected for the "Always-on Screen" setting.
While OFF is selected for the smart watch's "Always-on Screen" setting, the color LCD will turn off and the monochrome watch face will appear after a specific period of non-use. The monochrome watch face minimizes power consumption by providing timekeeping functions only.
Q9How can I change information displayed by a dial of the Authentic, Field, and Multi watch faces?
Tap a dial to change the information displayed there.

Location Memory

Q1What does the Location Memory app do?
The Location Memory app displays color maps.
You can display your current location, the route you covered, and other information.
You can use dictation to leave memos and marks on maps.
You can even download maps of specific locations so they are available even when you are in an area outside the range of your phone signal.
• When using an iPhone (iOS), be sure to pre-download maps.

Handling and Care

Q1Are there any precautions concerning water proofing?
The watch is water resistant up to 50 meters (5 atmospheres).
For more detail, visit here.

After submersion in seawater, use plain water to rinse all salt and dirt from the watch. In order to maintain water resistance, periodic replacement of the gaskets of the watch (about once every two or three years) is recommended.
Q2How do I fasten the band to my wrist?
There should be enough room between the band and your wrist so you can insert your finger. Tightening the band too tightly can cause you to sweat and make it difficult for air to pass under the band, which can lead to skin irritation.
Q3Is there any special handling for resin parts?
Allowing the watch to remain in contact with other items or storing it together with other items for long periods while it is wet can cause color on resin components to transfer to the other items, or the color of the other items to transfer to resin parts. Be sure to wipe off any water before storing the watch and make sure it is not in contact with other items.
Leaving a band where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from a leather band for long periods can cause it to become discolored.
Friction caused by certain conditions (strong external force, sustained rubbing, impact, etc.) can cause discoloration of painted components.
Daily use and long-term storage of the watch can lead to deterioration, breaking, or bending of resin components. The extent of such damage depends on usage conditions and storage conditions.
Q4What needs to be done for regular user maintenance?
You wear the watch next to your skin, just like clothing. Always keep it clean. To ensure the watch performs at the level for which it is designed, keep it clean by frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat, water and other foreign matter.
Whenever the watch is exposed to sea water or mud, rinse it off with clean fresh water.
For a resin band, wash with water and then wipe dry with a soft cloth. Note that sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any effect on your skin or clothing. Wipe with a cloth to remove the smudge pattern.
Not operating button for long periods can lead to later operation problems. Periodically press buttons to maintain proper operation.

Problems Caused by Poor Watch Care
Rust
・ Though the stainless steel used for the watch is highly rust-resistant, rust can form if the watch is not cleaned after it becomes dirty.
Dirt on the watch can make it impossible for oxygen to come into contact with the metal, which can lead to breakdown of the oxidization layer on the metal surface and the formation of rust.
・ Rust can cause sharp areas on metal components and can cause band pins to fly out of position or to fall out. If you ever notice any abnormality immediately stop using the watch and take it to your original retailer or to an authorized CASIO service center for (paid for) repair.
・ Even if the surface of the metal appears clean, sweat and rust in crevasses can soil the sleeves of clothing, cause skin irritation, and even interfere with watch performance.

Premature Wear
・ Leaving sweat or water on a resin band or storing it an area subject to high moisture can lead to premature wear, cuts, and breaks.

Skin Irritation
・ Individuals with sensitive skin or in poor physical condition may experience skin irritation, and should frequently clean the watch and band. Should you ever experience a rash or other skin irritation, immediately remove the watch and contact a skin care professional.
Q5Are there any precautions concerning putting on, taking off, or wearing the watch?
・ To prevent accidentally falling over and injury, carefully check the area around you to ensure you are in a safe place before looking at the display of the watch.
・ Looking at the watch while running or jogging on the open road, while riding a bicycle, or operating a motor vehicle can lead to accidents. Take care to avoid running into others.
・ While engaged in some activity (bicycle riding, mountain climbing, fishing, etc.), first make sure that any devices you may be using are fully stopped before looking at the watch display.
・ To avoid unexpected injury or skin rash due to allergic reaction, remove the watch before sleeping.
・ When picking up or otherwise coming into contact with a child, remove the watch to avoid possible injury to the child or skin rash due to allergic reaction.
・ Be sure to remove all protective stickers affixed to the watch and/or band before using it. Using the watch without removing protective stickers may result in the build-up of dirt between the watch/band and the sticker, which creates the risk of rust and skin rash.
・ Since the watch and the band come into direct contact with the skin, the conditions below may cause skin rash.

Example:
(1) When a wearer is allergic to metal
(2) When the watch or band is rusty dirty, sweaty, etc.
(3) When the wearer is in poor physical condition

・ Tightening the band too tightly can cause you to sweat and make it difficult for air to pass under the band, which can lead to skin irritation. Do not over-tighten the band.
・ Should you ever notice any abnormality, immediately stop using the watch and consult a physician.
・ If you do not plan to use the watch for a long time, thoroughly wipe it free of all dirt, sweat, and moisture, and store it in a location that is not exposed to high temperature, high moisture, or direct sunlight. It is also recommended that you use the setting screen to turn off watch power.
・ Do not allow the watch to come into contact with thinner, gasoline, solvents, oils, or fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain such ingredients. Doing so can cause discoloration of or damage to the resin case, resin band, and other parts.
・ If metal components is exposed to sweat or water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a well-ventilated location to dry.
・ Failure to clean dirt from metal components can lead to formation of rust, even if the components are stainless steel or plated.
