Things to check before using the watch

1. During regular timekeeping, observe the movement of the x Second Hand.

Is the x Second Hand moving smoothly at one-second intervals?

Is the x Second Hand moving at two-second intervals or is it stopped completely?

Power is low. Charge the watch by placing it in a location where it is exposed to light. For details, see “Charging the Watch” (page E-9).

YES

The watch is charged sufﬁ ciently. For details about charging, see “Charging the Watch” (page E-9).

2. Check the current location setting.

Use the procedure under “Specifying Your Current Location and Setting the Time” (page E-27) to conﬁ gure your location setting.

Important!

Proper time calibration signal reception and time settings depend on correct location setting. Make sure you conﬁ gure these settings correctly.

3. Set the current time.

Charging the Watch

The face of the watch is a solar cell 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

Whenever you are not wearing the watch, 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.

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-15) if its face is

blocked by your sleeve even only partially.

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.

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 x 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.

Level Hand Movement Function Status

1 Normal. All functions enabled

xx Second Hand moves at two-second

intervals.

zz Hour Hand, xx Second Hand and

cc Minute Hand stopped at 12 o’clock.

When power drops to Level 3, all functions will be disabled but the watch will x continue to keep time internally for about one week. If you recharge the battery sufﬁ ciently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for one week in an area where it is dark.

What happens when the watch is in the sleep state

All regular timekeeping hands move to 12 o’clock and stop. x

Minute Hand (elapsed time) moves to 0 and stops.

Auto Receive becomes disabled. x Internal timekeeping functions continue to operate normally. x

To recover from the sleep state

Move the watch to a well-lit area or press any button.

It can take up to 14 minutes for the watch to recover from the sleep state to normal operation. Do not perform any button operations during that time.

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 “Specifying Your Current Location and Setting the Time” (page E-27) for more information.

This section explains how the watch updates its time settings when the city name selected as the current location is in Japan or China, and is one that supports time calibration signal reception.

If your location setting is this:

HONG KONG (HKG) Shangqiu City (China)

TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)

E-16

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 above conditions 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.

Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)

Shangqiu (China) transmitter: 500 kilometers (310 miles) −

As of January 2011, China does not use Daylight Saving Time (DST). If China does x go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly. Using this watch in a country covered by a time calibration that is different from the

countries it supports may result in incorrect time indication due to local application of summer time, etc.

To get ready for a receive operation

The antenna of this watch is located on its 12 o’clock side. Position the watch with 1. 12 o’clock facing towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.

12 o’clock

Signal reception normally is better x 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.
