Connection with the watch is not possible while the phone is in the Airplane Mode. After exiting the phone’s Airplane Mode, go to the Home Screen and tap the “CASIO WATCHES” icon. Then on the watch, hold down (B) for at least two seconds until the second hand points to [R] twice.

On the phone, turn Bluetooth off and then back on, and then tap the “CASIO WATCHES” icon on the Home Screen. Then on the watch, hold down (B) for at least two seconds until the second hand points to [R] twice.

Turn on the phone and then tap the “CASIO WATCHES” icon. Then on the watch, hold down (B) for at least two seconds until the second hand points to [R] twice.

Pair the watch with the phone.

The watch will connect with the phone and perform auto time adjustment at around 12:30 a.m., 6:30 a.m., 12:30 p.m. and 6:30 p.m. The connection is automatically terminated after auto time adjustment is complete.

If your phone is unable to receive a signal because you are outside its service range or for some other reason, the watch may not be able to display the correct time. If this happens, connect the phone to its network and then correct the time setting.

Relative altitude is calculated based on changes in barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications.

The second hand will move to 9 o’clock if a reading is outside the allowable altitude measurement range (-700 m to 10,000 m (-2,300 to 32,800 feet)). If [ERR] is displayed, there may be a problem with the sensor.

There may be a problem with the sensor. Try taking another measurement.

If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.

Abnormal magnetism has been detected. Move away from any potential source of strong magnetism and try taking a reading again.

• If the display flashes again, it could mean that the watch itself has become magnetized. Move away from any potential source of strong magnetism, perform figure 8 calibration or 2-point calibration, and then try taking a reading again.

There is a problem with the sensor or there may be a source strong magnetic force nearby. Move away from any potential source of strong magnetism and try taking a reading again. If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.

[ERR] on the display could indicate a sensor problem.

• If [ERR] disappears after about one second, try performing 2-point calibration again.

• If [ERR] keeps appearing after multiple attempts, contact a CASIO service center or your original retailer.

Move away from any potential source of strong magnetism and try taking a reading again.

The second hand will move to 9 o’clock if a reading is outside the allowable barometric pressure measurement range (260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg)). If [ERR] appears on the display, there may be a problem with the sensor.

There may be a problem with the sensor. Try taking another measurement. If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.

The summer time setting (standard time/summer time) may be wrong.

While the watch is on your wrist, it may detect non-step movements and count them as steps.

Also, step count problems can also be caused by how the watch is being worn and abnormal arm movement while walking.

To avoid miscounting of non-walking movements, the step count is not displayed at the beginning of a walk.
It appears only after you have continued walking for about 10 seconds, with the number of steps you took during the first 10 seconds included in to the total.

[ERR] (error) indicates that sensor operation is disabled because of sensor or internal circuitry malfunction.
If the indicator remains on the display for more than three minutes or if it frequently appears, it could indicate a faulty sensor.

Contact a CASIO service center or your original retailer.

Is the alarm setting turned on? If it isn’t, turn it on so it will sound.

You can determine the current mode by checking the watch display. Use (D) to navigate between modes.

The battery is dead. Have the battery replaced.

This is due to the reason (or one of the reasons) below, and does not indicate malfunction. Simply wait until normal hand movement resumes.

• Watch is connected with a phone to correct its time setting.

The summer time setting may not be correct. Select the correct setting.

Strong magnetism or impact can cause the hands to go out of alignment. Adjust hand alignment.

• Check the information below to find out how to align the hands manually.

You can use CASIO WATCHES to set a favorite location as a fishing point.
With the exception of Tide Graph, correct information for the location you specify will be displayed. You can also disable display of the Tide Graph on the watch. Even if you do not display the Tide Graph on the watch, you can still view it using CASIO WATCHES’s FISH MEMO.

A fishing point can be set manually using watch operations.
You can improve the accuracy of the displayed information by configuring settings accordance with information available on the internet or in a newspaper.

①

Enter the FISH Mode.

Navigating Between Modes

②

Hold down (E) for at least two seconds. Release the button when [SET] starts to flash and then disappears from the display.

After the high tide time for that day appears, the minutes digits will become selected so you can change them.

③

Use (A) and (C) to change the high tide time minute setting.

④

Press (D).

This causes the hours digits to become selected.

⑤

Use (A) and (C) to change the high tide time hour setting.

⑥

Use (D) to navigate between setting items.

Each press of the button cycles through setting items as shown below.

⑦

Use (A) and (C) to specify the latitude, longitude, and time offset.

⑧

Press (E) to complete the setting operation.

• If you set a fishing point using watch operations, the watch fishing point may be different from the CASIO WATCHES fishing point.

The FISH MEMO sunrise and sunset times are calculated from the day’s latest FISH MEMO location information, which is obtained by CASIO WATCHES.
Because of this, if a FISH MEMO is obtained for a location that is different from the Fishing Point set on the watch, the sunrise and sunset times of the obtained FISH MEMO may end up being different from watch’s Fishing Point sunrise and sunset times.
Before obtaining a FISH MEMO, it is recommended you ensure that the watch’s Fishing Point is the same location as the FISH MEMO.

This indicates that battery power is getting low.
Have the battery replaced.

[RECOVER] may appear on the display when the watch’s battery power is low, or if you use the light or other function a number of times during a short period, which momentarily causes the battery level to go low. If this happens, all watch functions, except for timekeeping, are disabled.
If [RECOVER] remains on the display or if it keeps appearing, it may indicate that the battery needs to be replaced.
