Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to read this manual carefully.

Expose the watch to bright light to charge its battery before using it.

You can use this watch even as its battery is being charged by exposure to bright light.

Be sure to read “Power Supply” of this manual for important information you need to know when exposing the watch to bright light.

Keep the watch exposed to bright light

l l

Bright Light l l

Solar cell l l l l

The electricity generated by the solar cell of the watch is stored by a built-in 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 only partially covered.

• 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 to be 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.

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. 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 time calibration signal reception 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.

Make sure there are no metal objects nearby.

12 o’clock or

• Make sure the watch is facing the right way.

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

Inside or among buildings

Inside a vehicle

Near household appliances, office equipment, or a mobile phone

Near a construction site, airport, or other sources of electrical noise

Near hightension power lines

Among or behind mountains

• Signal reception is normally 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.

Reception Ranges

1,500 kilometers

Anthorn

500 kilometers

Mainflingen

• At distances further than about 500 kilometers from a transmitter, signal reception may not be possible during certain times of year or times of day. Radio interference may also cause problems with reception.

• 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

With auto receive, the watch receives the time calibration signal automatically up to six times a day. When any auto receive is successful, the remaining auto receive operations are not performed. The start times of the auto receive operations depend on the current Home City and DST settings.

Note

• Auto receive is performed only if the watch is in the Timekeeping Mode or World

Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while settings are flashing on the display).

• When a reception starts, the second hand will move at high speed to the 12 o’clock position where it will stop until the reception is complete.

• 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 easily receive the signal.

• When auto receive is turned on, the watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Do not perform any button operation within seven minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.

• Remember that reception of the calibration signal depends on the time kept 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

Timekeeping Mode time actually is the correct time.

About the Receiving Indicator

The receiving 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.

Receiving indicator

Weak

(Level 1)

Strong

(Level 4)

• Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.

• Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal reception.

• The Level 4 receiving indicator indicates that at least one of the auto calibration signal receive operation was successful. Note, however, that the Level 4 receiving indicator is cleared from the display when the first auto receive operation of the day is performed.

• The Level 4 receiving indicator appears on the Timekeeping Mode’s Receiving

Indicator and Seconds Count screen only. The Level 4 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.

Operation Guide 4321 4322

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. Make 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 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.

To check the current battery level

In the Timekeeping Mode, press C to display the battery level indicator.

1. In the Timekeeping Mode, hold down A until the city code starts to flash, which indicates the setting screen.

2. Press C nine times until the Power Saving on/off screen appears.

3. Press D to toggle Power Saving on ( ON ) and off

( OF ).

4. Press A to exit the setting screen.

• The Power Saving on indicator is on the display in all modes while Power Saving is turned on.

Auto Return Features

• If you leave the watch in the Alarm Mode or Hand Setting Mode, or with the battery level indicator displayed for two or three minutes without performing any operation, it returns to the Timekeeping Mode automatically.

• 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.

Scrolling

The B and D buttons are used in various modes and setting screens to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.

Initial Screens

When you enter the World Time or Alarm Mode, the data you were viewing when you last exited the mode appears first.

Radio-controlled Timekeeping Precautions

• Strong electrostatic charge can result in the wrong time being set.

• 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 automatically update the date and day of the week 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.

• Normally, the signal reception date shown by the last signal screen is the date data included in the received time calibration signal. When only time data is received, however, the last signal screen shows the date as kept in the Timekeeping Mode at the time of signal reception.

• If you are in an area where proper time calibration signal reception is impossible, the watch keeps time within ±20 seconds a month at normal temperature.

Operation Guide 4321 4322

• If you have problems with proper time calibration signal reception or if the time setting is wrong after signal reception, check your Home City code, DST (summer time), and auto receive settings. The following are the initial factory defaults for these settings.

Transmitters

This watch is designed to receive the time calibration signal transmitted from Anthorn,

England and the signal from Mainflingen, Germany.

• The following explains how the watch determines which transmitter it should check first.

Module 4321

In this case:

The first signal auto search operation after factory default settings are in effect, or after the city code has been changed

Any case other than the above.

The watch does this:

1. Checks the Mainflingen signal first.

2. If the Mainflingen signal cannot be received, checks the Anthorn signal.

1. Checks the last successfully received signal first.

2. If the last successfully received signal cannot be received, checks the other signal.

Module 4322

In this case:

The first signal auto search operation after factory default settings are in effect, or after the city code has been changed

Any case other than the above.

The watch does this:

1. Checks the Anthorn signal first.

2. If the Anthorn signal cannot be received, checks the Mainflingen signal.

1. Checks the last successfully received signal first.

2. If the last successfully received signal cannot be received, checks the other signal.

4321

• To find out the module number of your watch, look at its back cover. The Module number (4321 or 4322) is engraved inside the box on the back cover.

4322

Timekeeping

• Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.

• The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.

• The year can be set in the range of 2000 to 2099.

• The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.

• The current time for all city codes in the Timekeeping Mode and World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting.

• GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC*) data.

* UTC is the world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

The reference point for UTC is Greenwich, England.

12-hour/24-hour Timekeeping Formats

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also applied in all other modes.

• With the 12-hour format, the P (PM) indicator appears on the display for times in the range of noon to 11:59 p.m. and no indicator appears 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.

Illumination Precautions

An LED (light-emitting diode) and a light guide panel illuminate the face of the watch for easy reading in the dark. In any mode, press B to illuminate the face of the watch for about one second.

• The illumination provided by the light may be hard to see when viewed under direct sunlight.

• Illumination automatically turns off whenever an alarm sounds.

• Frequent use of illumination shortens the battery operating time.
