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).
See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
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”.
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 and date manually” 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.
Using this watch in a country covered by a time calibration that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.

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 “Important!” under “Time Calibration Signal Reception” and “Transmitters”.
See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.
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 for the China 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 facing 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.

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 14 minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within 14 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 your Home City, as kept in the Timekeeping Mode.

Illumination

Auto light switch on indicator
About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you position your wrist as described below in any mode. Note that this watch features a “Full Auto LED Light”, so the auto light switch operates only when available light is below a certain level. It does not illuminate the display under bright light.
The auto light switch is always disabled, regardless of its on/off setting, when any one of the following conditions exists.
-While an alarm is sounding
-While a signal receive operation is in progress
Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.
Wear the watch on the outside of your wrist.
Warning!
Always make sure you are in a safe place whenever you are reading the display of the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.
When you are wearing the watch, make sure that its auto light switch is turned off before riding a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down B for about three seconds to toggle the auto light switch on (auto light switch on indicator displayed) and off (auto light switch on indicator not displayed).
The auto light switch on indicator is on the display in all modes while the auto light switch is turned on.
An LED (light-emitting diode) illuminates the face of the watch for easy reading in the dark. The watch’s auto light switch turns on illumination automatically when you angle the watch towards your face.
The auto light switch must be turned on (indicated by the auto light switch on indicator) for it to operate.
See “Illumination Precautions” for other important information about using illumination.
To illuminate the display manually
In any mode (except when a setting screen is on the display), press B to turn on the illumination for about one second.
The above operation turns on illumination regardless of the current auto light switch setting.

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary 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.
Solar cell
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 special 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 special rechargeable battery to charge fully, contact your dealer or CASIO distributor about having it replaced.
Never try to remove or replace the watch’s special battery yourself. Use of the wrong type of battery can damage the watch.
The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 (C) 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 Power Recovery Mode indicator
The battery power indicator indicates you the current status of the rechargeable battery’s power.
Battery Power indicator
The flashing indicator 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.
At Level 5 (C), all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (M) after falling to Level 5 (C), reconfigure the current time, date, and other settings.
Display indicators reappear as soon as the battery is charged from Level 5 (C) to Level 2 (M).
The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5 (C). With 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 or Europe, or China you will need to change the Home City code setting to match your location whenever the battery drops to Level 5 (C).
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.
Power recovery mode indicator
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
After a full charge, timekeeping remains enabled for up to about six months.
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.
Exposure Level (Brightness)
Outdoor Sunlight (50,000 lux)
Sunlight Through a Window (10,000 lux)
Daylight Through a Window on a Cloudy Day (5,000 lux)
Indoor Fluorescent Lighting (500 lux)
For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications.

Overuse of display illumination or the beeper can cause the R (Recover) indicator to appear in the upper display, which indicates that the watch is in the battery power recovery mode. Face illumination, the alarm, the countdown timer alarm, time signals, and all hand operations are disabled in the power recovery mode. The watch continues to keep time internally, so normal timekeeping and function will resume as soon as battery power recovers to normal levels, which is indicated when the R indicator disappears.
If R (recover) appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light for some time to allow it to charge.

12-hour and 24-hour timekeeping
With the 12-hour format, the PM indicator appears to the left of the hour digits for times in the range of noon to 11:59 p.m. and no indicator appears to the left of the hour digits for times in the range of midnight to 11:59 a.m.
With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all other modes.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time. The time calibration signals transmitted from Mainflingen (Germany), Anthorn (England), or Fort Collins (the United States) include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the signals.
Though the time calibration signals transmitted by the Fukushima and Fukuoka/ Saga, Japan transmitters include summer time data, summer time currently is not implemented in Japan (as of 2009).
The default DST setting is Auto DST (

Radio-controlled Atomic Timekeeping Precautions
Strong electrostatic charge can cause the time setting to be thrown off.
The time calibration signal bounces off the ionosphere. Because of this, such factors
as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.
Even if the time calibration signal is received properly, certain conditions can cause the time setting to be off by up to one second.
The current time setting in accordance with the time calibration signal takes priority over any time settings you make manually.
The watch is designed to update the date and day of the week automatically for the period January 1, 2000 to December 31, 2099. Setting of the date by the time calibration signal cannot be performed starting from January 1, 2100.
This watch can receive signals that differentiate between leap years and non-leap years.
Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signal conditions can limit reception to time data only.
If you are in an area where proper time calibration signal reception is impossible, the watch keeps the time with the precision noted in “Specifications”.
If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your current city code and DST (summer time) settings.
The Home City setting reverts to the initial default of battery power drops to Level 5 (C) or when you have the rechargeable battery replaced. If this happens, change the Home City to the setting you want.
Transmitters
The time calibration signal received by this watch depends on the currently selected Home City code.
When a U.S. time zone is selected, the watch receives the time calibration signal transmitted from the United States (Fort Collins).
When a Japanese time zone is selected, the watch receives the time calibration signal transmitted from Japan (Fukushima and Fukuoka/Saga).
When a European time zone is selected, the watch receives the time calibration signals transmitted from Germany (Mainflingen) and England (Anthorn).
When a China time zone is selected, the watch receives the time calibration signals transmitted from China (Shangqiu City).
• When your Home City is LIS, LON, MAD, PAR , ROM, BER, STO, ATH, MOW (which can receive both the Anthorn and Mainflingen signals), the watch first tries to pick up the signal it last successfully received. If that fails, it tries the other signal. For the first receive after you select your Home City, the watch tries the nearest signal first (Anthorn for LIS, LON, Mainflingen for MAD, PA R, ROM , BER, STO, ATH, and
MOW).
Auto Return Features
If you leave the watch with a flashing setting on the display for two or three minutes without performing any operation, the watch automatically exits the setting screen.
The watch will return to the Timekeeping Mode automatically if you do not perform any operation for two or three minutes in the Alarm Mode.
High-Speed Movement
The D and B buttons are used to change the hand setting in various setting modes. In most cases, holding down these buttons will start high-speed movement of the applicable hand(s).
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing when you last exited the mode appears first.
When turned on, the Power Saving function enters a sleep state automatically whenever the watch is left in an area for a certain period where it is dark. The table below shows how watch functions are affected by the Power Saving function.
