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.
xEnable the watch’s Power Saving function (page E-17) 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-11
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.

|
x The flashing 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-12 |
E-13 |
|
|
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, reconfigure 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 operations during a short period may cause all of the battery power indicators (H, M, and L) to start flashing. 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 flashing. This indicates that the functions listed above are enabled again.
xIf all of the battery power indicators (H, M, L) are flashing and the CHG (charge) message also is flashing, it means the battery level is very low. Expose the watch to bright light as soon as possible.
xFrequent flashing 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.

x The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.
x The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.
To recover from the sleep state
Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page E-65).
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-44) 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-18 |
E-19 |
Operation Guide 5561
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), Mainflingen (Germany) |
|
ATH, MOW |
||
|
||
HKG, BJS |
Shangqiu City (China) |
|
TPE, SEL, TYO |
Fukushima (Japan), Fukuoka/Saga (Japan) |
|
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 configure Home City settings” (page E-40) for information about how to do this.

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-27.
Auto Receive
x With Auto Receive, the watch performs the receive operation each day automatically up to six times (up to five 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 configuring settings, while a countdown timer operation is in progress, or while the hands have been moved for easier viewing of digital information (page E-73).
x You can use the procedure under “To enable or disable auto receive” (page E-32) to enable or disable auto receive.

x 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.
x If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications” (page E-85).
x The receive operation is disabled under any of the following conditions.
−While power is at Level 3 (L) or lower (page E-13)
−While the watch is in the power recovery mode (page E-15)
−When the watch is in the function sleep state (“Power Saving”, page E-17)
−While a countdown timer operation is in progress (page E-55)
−While the hands are in positions to allow easier viewing (page E-73)
x A receive operation is cancelled if an alarm sounds while it is being performed.
E-33
x The Home City setting reverts to the initial default of TYO (Tokyo) whenever the battery power level drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the Home City to the setting you want (page E-40).
