Acquiring Position information

After the watch acquires GPS position information it automatically determines your current time zone and summer time setting, and updates its current time and day settings accordingly.

Be sure to perform a receive operation to acquire position information in the cases below.

• ● Immediately after purchasing the watch
• ● After you have moved to another time zone

Put the watch in the Timekeeping mode to acquire position information.

To check if the watch is in the Timekeeping Mode

The watch is in the Timekeeping Mode when the mode hand is pointed at the current day of the week.
If the mode hand is not pointed at a day of the week, hold down for at least two seconds to return to the Timekeeping Mode.

To acquire position information

• Hold down the lower right button for at least three seconds until the second hand moves to T+P.
• Release when the second hand is pointed at T+P. The watch will acquire information for the watch's current location at this time. This operation takes anywhere from 30 seconds to two minutes.
• If the acquisition operation is successful, the second hand will point to Y (YES), and the time and day settings will be adjusted automatically in accordance with the information.

If the second hand is pointed at N (NO), move to a location where GPS signal reception is good and perform the above operation from step again.

Summer Time

The initial factory default summer time setting for all cities (time zones) is AUTO.
A successful watch location information acquisition operation automatically receives summer time settings for the current location.

After the watch acquires position information, the watch will automatically perform a GPS signal or time calibration signal receive operation.

● After you have moved to another time zone, first perform a position information acquisition operation.

Time Calibration Signal and GPS Signal Receive Operation

	Time Calibration Signal	GPS Signal
Nighttime	Between midnight and 5:00 a.m. The watch will automatically attempt to receive a time calibration signal and adjust its time setting up to six times each night.	No auto reception (Manual reception possible.)
During the day	No reception	Between 6:00 a.m. and 10:00 p.m.Exposing the watch to continuous light will automatically trigger a GPS signal receive operation and the watch will update its time setting.
Location	Locate the watch near a window.	Outdoors where the sky is visible and not blocked by buildings, trees, or other objects, orient the watch so its face is pointed straight up at the sky. In areas where reception is poor, keep the watch face oriented upwards and do not move the watch.

Correcting an Incorrect Time Setting

Acquiring GPS Time Information

• ● Put the watch in the Timekeeping Mode to acquire time information.

To acquire time information

• Hold down the lower right button for at least one seconds until the second hand moves to TIME.
• Release when the second hand is pointed at TIME. The watch will acquire time information for the watch's current location at this time. This operation takes anywhere seven seconds to one minute.
• If the time acquisition operation is successful, the second hand will point to Y (YES), and the current time and day settings will be adjusted automatically.

If the second hand is pointed at N (NO), move to a location where GPS signal reception is good and perform the above operation from step again.
