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.
x On the dashboard of a car parked in direct sunlight x Too close to an incandescent lamp
x Under direct sunlight
Important!
x Allowing the watch to become very hot can cause the digital displays to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.
x Turn on the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.
E-13
x 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. Expose the watch to bright light whenever possible.
Power Levels
You can get an idea of the watch’s power level by observing the battery power indicator in the lower digital dial.

x The fl ashing LOW message at Level 3 (L) tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
E-15
x At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (M) after falling to Level 5, reconfi gure the current time, date, and other settings.
x Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M).
x Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.
x The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
Power Recovery Mode
xPerforming multiple illumination, beeper, and/or high-speed hand movement operation during a short period may cause all of the battery power indicators (H, M, and L) to start fl ashing in the lower digital dial. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, and hourly time signal operations will be disabled until battery power recovers.
xBattery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will stop fl ashing. This indicates that the functions listed above are enabled again.
xIf all of the battery power indicators (H, M, L) are fl ashing and the CHG (charge) message also is fl ashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.
xFrequent fl ashing of all of the battery power indicators (H, M, L) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

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 “Configuring Current Time and Date Settings Manually” (page E-48) 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.
E-21
If your Home City Code setting is this: |
The watch can receive the signal from the |
|
transmitter located here: |
||
|
||
LIS, LON, MAD, PAR, ROM, BER, STO, |
Anthorn (England), Mainfl ingen (Germany) |
|
ATH, MOW |

|
|
|
HNL, ANC, YVR, LAX, YEA, DEN, MEX, |
Fort Collins, Colorado (United States) |
|
CHI, NYC, YHZ, YYT |
||
|
Important!
x The areas covered by MOW, HNL and ANC are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
x When HKG or BJS is selected as the Home City, only the time and date are adjusted according to the time calibration signal. You need to switch manually between standard time and daylight saving time (DST) if required. See “To confi gure Home City settings” (page E-42) for information about how to do this.

Signals are receivable in the Taiwan area when reception conditions are good.
x 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 infl uence of the conditions listed above becomes even greater.
x 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.
−Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
−Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
−Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
−Shangqiu (China) transmitter: 500 kilometers (310 miles)
x As of December 2010, 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.Confirm that the watch is in the Timekeeping Mode. If it isn’t, use C to enter the Timekeeping Mode (page E-38).
2.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.
x Signal reception normally is better at night.
x The receive operation takes from three to eight minutes, but in some cases
it can take as long as 16 minutes. Take care that you do not perform any button operation or move the watch during this time.

3.What you should do next depends on whether you are using Auto Receive or Manual Receive.
x Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” below for details.
x Manual Receive: Perform the operation under “To perform manual receive” on page E-29.
Auto Receive
x 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.
x When a calibration time is reached, the watch will perform the receive operation only if it is in the Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is reached while you are confi guring settings, while a countdown timer operation is in progress, or while the hands have been moved for easier viewing of the digital dials (page E-79).
x You can use the procedure under “To turn auto receive on and off” (page E-34) to enable or disable auto receive.
To perform manual receive
Receiving
In the Timekeeping Mode, hold down D until the watch beeps.
xA signal level indicator (L1, L2, or L3, see page E-32) appears in the lower digital dial after reception starts. Do not move the watch or perform any button operation
until GET or ERR appears in the right digital dial.
