Solar Charging

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

Charging the Watch

●

When you are not wearing the watch, put it in a location where it is exposed to bright light.

While you are wearing the watch, make sure that its face (solar panel) is not blocked from the light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Checking the Charge Level

●

Immediately after you press (C) to return to the Timekeeping Mode, the

day of the week hand will indicate the battery charge level. After a short while, the day of the week hand will return to indicating the current day of the week.

Good (high charge)

Good (medium charge)

Low Battery

Remaining Charge and Dead Battery

●

You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.

Power Saving

●

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause the second hand to stop, and the watch will enter Level 1 power saving. If the watch is left in this condition for six or seven days, all hands will stop and the watch will enter Level 2 power saving.

Level 1 :

Basic timekeeping functions are operational.

Level 2 :

Only the day indicator is operational.

Note

●

Note that the watch also may enter the power saving state if its face is blocked from light by your sleeve while you are wearing it.

●

The watch will enter power saving from the Timekeeping Mode only.

Recovering from Power Saving

●

Operation

Press any button or place the watch in a welllit area to recover from power saving.

Auto Time Adjustment

Your watch can receive time calibration signals and connect with a phone to obtain information that it uses to adjust its date and time setting.

●

First Use of the Watch

Immediately after purchasing the watch, it will acquire GPS location information and configure a Home City based on your current location.

Acquiring GPS Position Information

Manually

●

Normal Use of the Watch

Your watch automatically receives a time calibration signal or GPS signal (time information)

regularly each day

and adjusts its time setting. This means its time setting is always accurate without the need for any adjustment by you.

Leap Second Reception

GPS signal reception each year on June 1 or later and on December

1 or later also receives

leap second information.

Note

●

It can take as long as 13 minutes to complete leap second information reception.

●

Leap second information receive is repeated until information receipt is complete.

●

Once leap second information receive is complete, the watch will not make any attempt to receive it again until the following June 1 or December 1.

●

When connecting with a phone to adjust the watch date and time settings, leap seconds will also be received along with the time information. If this happens, leap seconds may not be received when receiving a GPS signal.

Auto Time Calibration Signal Receive

An automatic time calibration signal receive operation is performed and the time and day settings are adjusted between midnight and 5:00 a.m. Once a signal receive operation is successful, no more auto receive operations are performed that day.

Getting ready

Enter the Timekeeping Mode.

Navigating Between Modes

Place the watch near a window or some other location appropriate for signal reception.

●

The second hand points to “RC” while time calibration reception in progress.

●

When the receive operation is successful, the time and day settings will be adjusted automatically.

Note

●

Reception takes anywhere from about two minutes to about 10 minutes. It can take as long as 20 minutes.

Signal Reception Precautions

●

When the watch is unable to adjust its time in accordance with a calibration signal for some reason, average timekeeping accuracy is within ±15 seconds per month.

●

Note that an internal decoding process the watch performs after it receives a signal may cause the time setting to be slightly off (by less than one second).

●

GPS signal and time calibration signal reception will not be possible under any of the watch conditions described below.

ー

While battery power is low

ー

While the watch is in the Airplane Mode, Stopwatch Mode, Timer Mode, or Alarm Mode

ー

When power saving is at Level 2 (GPS signal reception also is not possible at Level 1.)
