Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

E-16

Power Levels

Moves at two-second intervals.

E-18

Whenever you are not wearing the watch, be sure to leave it in a location where it is exposed to light.

Best charging

performance is achieved by exposing the watch to light that is as strong as possible.

You can get an idea of the watch’s power level by observing the movement of the Timekeeping Mode.

If the

Important!

Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down. Storing the watch for long periods in an area where there is no light or wearing it in

such a way that it is blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

Operation Guide 5142

A short while after exposing the watch to light after its battery charge has run down x will cause the x Second Hand to move counterclockwise until it stops at second 57 on the face. This indicates that charging has started. See page E-21 for information about required charging times.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to overuse of the alarm tone over a short period. Note that all operations are disabled while the watch is in the power recovery mode. The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

E-20

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

There actually are two sleep state levels: “second hand sleep” and “function sleep”.

Elapsed Time in Dark Operation

60 to 70 minutes (second hand sleep)

6 or 7 days (function sleep)

The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch x is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state. The watch will not enter a sleep state while it is in the Stopwatch Split Mode,

Stopwatch Lap Mode, or Countdown Timer Mode.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Conﬁ guring Current Time and Date Settings Manually” (page E-55) for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

Even when the watch is within range of a transmitter, signal reception may be x impossible due to the effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the inﬂ uence of the conditions listed above becomes even greater. Signal reception may not be possible at the distances noted below during certain times

of the year or day. Radio interference may also cause problems with reception.

To get ready for a receive operation

Conﬁ rm that the watch is in the Timekeeping Mode. If it isn’t, push in and hold the 1. crown for at least two seconds to enter the Timekeeping Mode.

Place the watch in a location where signal reception is good.2.

12 o’clock

E-30

What you should do next depends on whether you are using Auto Receive or 3. Manual Receive.

Auto Receive: Leave the watch over night in the location you selected in step 2.

See “Auto Receive” on page E-32 for details. Manual Receive: Perform the operation under “To perform manual receive” on x page E-33.

Auto Receive

With Auto Receive, the watch performs the receive operation each day automatically up to six times (up to ﬁ ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed. When a calibration time is reached, the watch will perform the receive operation

only if it is in the Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you are conﬁ guring settings.

E-32

Position the watch as shown in the x nearby illustration, with 12 o’clock pointed towards a window. Make sure there are no metal objects nearby. Signal reception normally is better

at night. The receive operation takes from x two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operation or move the watch during this time.

The 2. x Second Hand indicates the operations the watch is currently performing.

Radio-controlled Atomic Timekeeping Precautions

Strong electrostatic charge can result in the wrong time setting. Even if a receive operation is successful, certain conditions can cause the time x setting to be off by up to one second. The watch is designed to update the date and day of the week automatically for

the period January 1, 2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.

If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Speciﬁ cations” (page E-105). The receive operation is disabled under any of the following conditions. x

While power is at Level 2 or lower (page E-18) − While the watch is in the power recovery mode (page E-20) − While the watch is in the function sleep state (power saving, page E-22) − While a countdown time operation is in progress (page E-73) −

A receive operation is cancelled if an alarm sounds while it is being performed. x
