Keep the watch exposed to bright light

The electricity generated by the solar cell of the watch is stored by a rechargeable battery. Leaving or using the watch where it is not exposed to light causes the battery to run down. Make sure the watch is exposed to light as much as possible.

• When you are not wearing the watch on your wrist, position the face so it is pointed at a source of bright light.
• You should try to keep the watch outside of your sleeve as much as possible. Charging is reduced significantly if the face is covered only partially.

• The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will result in some watch functions being disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.
This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga). 
Current Time Setting 
This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can perform a manual procedure to set the time and date, when necessary.

• The first thing you should do after purchasing this watch is to specify your Home City (the city where you normally will use the watch). For more information, see "To specify your Home City" below.
• When using the watch outside the areas covered by the time signal transmitters, you will have to adjust the current time setting manually as required. See “Timekeeping” for more information about manual time settings.
• The U.S. time calibration signal can be picked up by the watch while in North America. The term "North America" in this manual refers to the area that consists of Canada, the continental United States, and Mexico.
• 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 specify your Home City

1. In the Timekeeping Mode, hold down A until the city code starts to flash, which indicates the setting screen.
2. Press D (east) and B (west) to select the city code you want to use as your Home

Make sure there are no metal objects nearby.

  

• Proper signal reception can be difficult or even impossible under the conditions listed below.

  

• Signal reception normally is better at night than during the day.
• Time calibration signal reception 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 operations or move the watch during this time.
• The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

• Home City Code	Transmitter	Frequency
  LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW*	Anthorn (England)	60.0 kHz
  HKG, BJS	Shangqiu City (China)	68.5 kHz

  	Fukuoka/Saga (Japan)	60.0 kHz
  HNL*, ANC*, YVR, LAX, YEA, DEN, MEX, CHI, NYC, YHZ, YYT	Fort Collins, Colorado (the United States)	60.0 kHz

• Time crasation sed by the MieS and so Monito codes may ia far prom tens with signal reception.
• Calibration signal reception is disabled while a countdown timer operation is in progress.

Approximate Reception Ranges U.K. and German Signals

• Signal reception may not be possible at the distances noted below during certain times of the year or day. Radio interference also may cause problems with reception. Mainflingen (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: 1,500 kilometers (910 miles) 
• Even when the watch is within the reception range of the transmitter, signal reception will be impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal changes.
• See the information under "Signal Reception Troubleshooting" if you experience problems with time calibration signal reception.

About Auto Receive

The watch receives the time calibration signal automatically up to six times a day (five times a day for the Chinese calibration signal). When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City

Note

• When a calibration time is reached, the watch will receive the calibration signal only if it is in either the Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached while you are configuring settings.
• Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily. 
• The watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within seven minutes before or after the calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.

About the Signal Strength Indicator

The signal strength indicator shows the strength of the calibration signal being reenged is strongest. The signal streng indicator is displayed aire an au signal manual receive operation is in progress.

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the signal strength indicator to indicate signal strength.
• Use the signal strength indicator as a guide for checking signal strength and for finding the best location for the watch during signal receive operations.
• Following reception of the time calibration signal and calibration of the watch's time setting, the RCVD indicator will remain on the display in all modes. The RCVD indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.
• The RCVD indicator is displayed only when the watch is able to receive both time and date data successfully. It does not appear when only time data is received.
• The RCVD indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the RCVD indicator disappears from the display each day when the first auto-receive operation of the day is performed.

To perform manual receive

1. Enter the Timekeeping Mode.
2. Hold down D for about two seconds until the RCVD indicator starts to flash on the display. This indicates that manual receive is in progress.
   • Time calibration signal reception takes from two to seven minutes. Take care that you do not perform any button operations or move the watch during this time.
   • If the receive operation is successful, the reception date and time appear on the display, along with the GET indicator.
3. After manual receive is complete, press D to return to normal timekeeping.
   • The watch also will return to normal timekeeping if you do not perform any button operation for about one or two minutes.
