Warning! Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

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.

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

Checking the Current Power Level

You can use the procedure below to determine the watch’s current power level. Certain functions will be disabled when the power level is low. If the power level is low, leave the watch in a location where its face (solar panel) is exposed to light.

To check the current power level

1. In the Timekeeping Mode, press B. The x

MID (Middle), or LOW to indicate the power level.

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.

HIGH

MID: Middle

LOW

When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.

• The watch may enter a

sleep state (page E-20) if its face is blocked by your sleeve even only partially.

calibration signal receive operation result.

• See “To check the result of the latest receive operation” (page E-30).

3. Press B to return to regular timekeeping.

• The watch will also return to regular timekeeping if you do not perform any

operation for about 10 seconds.

E-16

• When power drops to Level 3, all settings (including timekeeping) will be cleared.

Recharging the battery will reset all settings to their initial factory defaults.

• When the watch is at Level 3, exposing it to light for a while will cause the x

Hand to move to the position of second 57. This indicates that charging has started.

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 continuous signal reception or other operations 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.

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

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

See “Auto Receive” on page E-28 for details.

• Manual Receive: Perform the operation under “To perform manual receive” on

page E-29.

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-28

• Position the watch as shown in the

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

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.

E-25

• Signal reception may be difﬁ cult or even impossible under the conditions

described below.

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

setting to be off by up to one second.

• The watch is designed to update its day setting automatically for the period from

January 1, 2000 to December 31, 2099. Updating of the day setting 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-79).

• The receive operation is disabled under any of the following conditions.

− While power is at Level 2 or lower (page E-17)

− While the watch is in the power recovery mode (page E-18)

− While the watch is in the function sleep state (power saving, page E-20)

− While the watch is in the World Time Mode (page E-49)

− While a countdown timer operation is in progress (page E-60)

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

Using the Stopwatch

You can use the Stopwatch Mode to measure elapsed time and lap times, and to recall lap times. Up to 10 lap times can be stored in memory. There is also memory to record the fastest lap time. Though no more lap times are stored after 10 times are in memory, the fastest lap time continues to be updated as required. Starting a new elapsed time operation clears all of the memories (including fastest lap time).

What is a lap time?

A lap time is the time elapsed over a speciﬁ c segment of a race.

Example: Car race on an oval track

• If you think that the time indicated for the selected World Time City is not correct,

it probably means that there is something wrong with your Home City settings. Use the procedure under “To conﬁ gure Home City settings” (page E-37) to correct the Home City settings.

■ The hands of the watch suddenly start moving at high speed, even when I do not perform any operation.

This could be due to any one of the following causes. In all cases, the hand movement does not indicate malfunction, and should stop shortly.

• The watch is recovering from a sleep state (page E-20).

E-70

• The period when summer time is applied in the location where you are using the

watch may be different from the period set for your currently selected Home City. Use the procedure under “To switch between standard time and summer time manually” (page E-40) to switch from AT (AUTO) to STD (for standard time) or DST (for summer time).

■ The time and date settings are off.

This could indicate that the watch has been exposed to magnetism or strong impact, which has caused problems with proper hand and day indicator alignment. Adjust the watch’s hand and day indicator home position alignment (page E-65).

Possible Cause Remedy Page

• You are wearing or moving the watch,

or performing a button operation during time calibration signal receive operation.

• The watch is in an area with poor

reception conditions.

You are in an area where signal reception is not possible for some reason.

The alarm time was reached during time calibration signal reception.

The calibration signal is not being transmitted for some reason.
