••When power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently 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.

2. Check the current location setting.
Use the procedure under “Specifying Your Current Location and Setting the Time” to configure your location setting.
Important!
Proper time calibration signal reception and time settings depend on correct location setting. Make sure you configure these settings correctly.
3. Set the current time.
••To set the time using a time calibration signal See “To get ready for a receive operation”.
••To set the time manually
See “Specifying Your Current Location and Setting the Time”.
The watch is now ready for use.
••For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic Timekeeping”.
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a

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.

What happens when the watch is in the sleep state
••All hands move to 12 o’clock and stop.
••Auto Receive becomes disabled.

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” 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: | The watch can receive the signal from the transmitter located here: |
HONG KONG (HKG) | Shangqiu City (China) |
TOKYO (TYO) | Fukushima (Japan), Fukuoka/Saga (Japan) |
Approximate Reception Ranges
Japanese Signal | Chinese Signal | |
Fukushima | 500 kilometers | Changchun |
500 kilometers |
| Beijing |

| Shangqiu |
Fukuoka/Saga |
| Shanghai |

••Even when the watch is within range of a transmitter, signal reception may be 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 influence 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 2009, China does not use Daylight Saving Time (DST). If China does go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly.
To get ready for a receive operation
1.The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing towards a window as shown in the nearby illustration. 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

that you do not perform any button operation or move the | ||

or | watch during this time. | |
