General Guide

• Press C to change from mode to mode.
• In any mode (except when a setting screen is on the display), press L to illuminate the display.

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 City.

3. Press A to exit the setting screen.
   • Normally, your watch should show the correct time as soon as you select your Home  City code. If it does not, it should adjust automatically after the next auto receive operation (in the middle of the night). You also can perform manual receive or you can set the time manually.
   • The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Time Calibration Signal Reception” and “Transmitters”.
   • See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.
   • You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.
   • Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HNL (Honolulu), and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off”. 

Time Calibration Signal Reception 
There are two different methods you can use to receive the time calibration signal: auto-receive and manual receive.

• Auto Receive
  With 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. For more information, see “About Auto Receive”.
• Manual Receive
  Manual receive lets you start a time calibration receive operation with the press of a button. For more information, see “To perform manual receive”.
  Important!

• When getting ready to receive the time calibration signal, position the watch as shown in the nearby illustration, with its 12 o’clock side pointing towards a window. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby.

  

• Make sure the watch is facing the right way.

• 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,	Anthorn (England)	60.0 kHz
  BER, STO, ATH, MOW*
  HKG, BJS	Shangqiu City (China)	68.5 kHz
  TPE, SEL, TYO	Fukushima (Japan)	40.0 kHz
  	Fukuoka/Saga (Japan)	60.0 kHz
  HNL*, ANC*, YVR, LAX, YEA,	Fort Collins, Colorado	60.0 kHz
  DEN, MEX, CHI, NYC, YHZ, YYT	(the United States)

• The areas covered by the HNL, ANC, and MOW city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems 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 received. For best reception, be sure to keep the watch in a location where signal strength is strongest. The signal strength indicator is displayed while an auto or 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.
   • If the latest reception fails but a previous reception was successful, the RCVD indicator will be on the display.
   • Note: To interrupt a receive operation and return to normal timekeeping, press D.

To turn auto receive on and off

1. In the Timekeeping Mode, press D to display the last successful receive time and date screen.
2. Hold down A until the current auto receive setting (ON or OFF) starts to flash. This is the setting screen.
   Note that the setting screen will not appear if the currently selected Home City is one that does not support time calibration reception.

Power Supply

This watch is equipped with a solar cell and a rechargeable battery that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.
Example: Orient the watch so its face is pointing at a light source.

• The illustration shows how to position a watch with a resin band.
• Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc.
• 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.

Important!

• 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 rechargeable battery power to run down. Be sure that the watch is exposed to bright light whenever possible.
• This watch uses a rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.
• Never try to remove or replace the watch’s rechargeable battery yourself. Use of the wrong type of battery can damage the watch.
• All data stored in memory is deleted, and 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
• Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Battery Power Indicator and Recover Indicator
The battery power indicator on the display shows you the current status of the rechargeable battery’s power.

• The flashing LOW indicator at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
• At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.
• The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5. Wth this Home City code setting, the watch is configured to receive the time calibration signals of Japan. If you are using the watch in North America, Europe, or China, you will need to change the Home City code setting to match your location whenever the battery drops to Level 5.
• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.
• 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 
• If you use the light or alarms a number of times during a short period, all segments of the battery power indicator flash and the following operations become temporarily disabled as battery power recovers
  • Display illumination
  • Alarm and hourly time signal
  • Time calibration signal receptio
• After some time, the battery power indicator should stop flashing to indicate that battery power is back to normal. At this time the watch should return to normal operation.
• If the battery power indicator frequently flashes, it means that battery power is low. Leave the watch in bright light to allow it to charge.

Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.
Warning
Leaving the watch in bright light to charge its rechargeable battery 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

Charging Guide
The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations.

• For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications.
• Stable operation is promoted by frequent exposure to light.

Recovery Times
The table below shows the amount exposure that is required to take the battery from one level to the next.

The above exposure time values are all for reference only. Actual required exposure times depend on lighting conditions.
