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.

Important!

●

Depending on light intensity and local conditions, to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under hightemperature conditions like the ones described below.

ー

On the dashboard of a vehicle

parked in the sun

ー

Near an incandescent light bulb or

other source of heat

ー

Under direct sunlight or in other hot

areas for long periods

the watch may become hot

●

Checking the Charge Level

Immediately after you press (C) to return to the Timekeeping Mode, the mode hand will indicate the battery charge level. After a short while, the mode hand will indicate 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.

Important!

●

Should the battery go low or go dead,

Power Saving

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 5:50 a.m. will cause the second hand to stop, and the watch to 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, perform a crown operation, or place the watch in a well-lit area to recover from power saving.

●

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.

●

Triggering Immediate Time Adjustment

The watch will synchronize its time setting with that of an online time server whenever a connection is established between it and a phone. Perform the operation below to connect

the watch with a phone whenever you want to have the watch’s time setting synchronized with that of an online time server.

Hold down (B) for about 0.5 seconds.

Release

the button as soon as the second

hand points to e.

When the watch connects with a phone, the second hand will move to

[Y(YES)], and then the watch’s time setting will be synchronized with that of an online time server.

●

The connection is terminated automatically after time adjustment is complete.

Note

●

If the watch time is adjusted by connection with a phone, the watch’s Home City setting will change to the city that is being used for the phone’s time

setting. If summer time is in effect in the city being used for the phone’s time setting, the watch’s time setting will also become summer time.

●

If the watch does not indicate the correct time even if it is able to connect with a phone, adjust the hand and day indicator positions.

Time Adjustment Using a Time Calibration Signal

Overview

The watch’s time and day settings can be adjusted in accordance with a received time signal.

Important!

●

In order to make it possible for the current time setting to be adjusted correctly based on time calibration signal reception, you need to specify the

time zone where you are using the

watch.

●

However, if the watch was unable to connect with a phone even once for time adjustment during the previous day while connection with a phone is being used, it will automatically try to receive a time calibration signal.

Note

●

Areas where time calibration signal reception is supported are limited. When

the watch in an area where time calibration signal reception is not possible, connect with a phone to adjust time and day settings.

Time Calibration Signal Reception

Ranges

●

If the watch does not indicate the correct time even after it receives a time calibration signal, correct the hand and day indicator positions.

Chinese Time Calibration Signal (BPC)

●

U.S. Time Calibration Signal (WWVB)

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

Manual Time Calibration Signal Receive

Place the watch near a window or some

other location appropriate for time signal reception.

Enter the Timekeeping Mode.

Navigating Between Modes

Hold

down (B) for about 1.5 seconds until

the second hand points to [RC].

This indicates that the receive operation

started. After the receive operation is

has complete, the watch’s time and day settings will be adjusted accordingly.

Note

●

U.K. (MSF) and German (DCF77) Time Calibration Signal

Note

●

Even if you are within the normal reception range of a time calibration signal, reception may be made impossible by the following factors: geographic contours, weather, the season, the time of day, wireless noise.

●

Reception

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

●

If the watch connects with a phone and adjusts its time setting, the watch will not perform auto receive of a time calibration signal for the rest of that day or the next day.

●

Reception

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

●

Time calibration signal reception is better at night than during the day.

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

cause the time setting to be slightly off

may (by less than one second).

●

Time calibration signal reception is not possible under the conditions described below.

ー

While battery power is low

ー

While in the Stopwatch Mode

ー

At Power Saving Level 2

ー

While the crown is pulled out

ー

While the Home City setting is one where

time signal reception is not possible

ー

While the watch is outside the time signal

reception range
