Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to carefully read this manual and keep it on hand for later reference when necessary.

•

This watch does not have a time zone that corresponds to the Greenwich

Mean Time differential of –3.5 hours. Because of this, the radio-controlled timekeeping and World Time functions will not display the correct time for

Newfoundland, Canada.

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

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

•

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

If the digital display of the watch is blank...

Power saving indicator

If the Power Saving indicator ( ) is flashing on the display, it means that the display is blank because the watch’s Power Saving function has turned it off to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever your watch is left for a certain period in an area where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.

•

The initial factory default setting is Power Saving on.

•

The watch will recover from the sleep state if you move

• it to a well-lit area, if you press any button, or if you angle the watch towards your face for reading.

See “Power Saving Function” for more information.

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 automatically picks up the time calibration signal five times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more information, see “About Auto Receive”.

•

Manual Receive

Manual receive lets you start a 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.

Resin Band Metal Band

•

The watch should not be on its side or facing the wrong way.

Operation Guide 3347

•

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 six minutes, but in some cases it can take as long as 12 minutes. Take care that you do not perform any button operations or move the watch during this time.

600 miles

2,000 miles

Fort Collins

•

•

•

Under good reception conditions, signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.

At distances further than about 600 miles (1,000 kilometers) from the Fort Collins transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.

See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful.

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).

Auto receipt 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 six minutes everyday when the time in the Timekeeping Mode reaches each of the five calibration times. Do not perform any button operation within six minutes before or after any of the five calibration times. Doing so can interfere with correct calibration.

•

Remember that reception of the calibration signal depends on the time kept in the digital display. Reception will be performed whenever the display shows one of the five calibration times, regardless of whether or not the displayed time is actually the correct time.

•

When two, three, four, or five receptions are successful, the watch uses the data of the last reception for calibration. When only one reception is successful, the watch uses the data of the successful reception.

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 0)

Strong

(Level 3)

•

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 3 receiving indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting.

The Level 3 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.

•

The Level 3 receiving indicator indicates that at least one of the five calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared from the display at 3:00 a.m. each day.

To perform manual receive

1. Place the watch on a stable surface so its top (12

Receiving indicator o’clock side) is facing towards a window.

2. In the Timekeeping Mode, hold down D for about two seconds until the watch beeps.

3. After you release D , the display will alternate between the current time and date, and the letters RC!

. This indicates that signal reception is in progress.

•

•

Time calibration signal reception normally takes from two to six minutes. Take care that you do not perform any button operations or move the watch during this time.

After signal reception is complete, the display of the watch changes to the last signal screen.

Note

•

To interrupt a reception and return to the Timekeeping Mode, press D .

•

If reception is unsuccessful, the message ERR appears on the display for about

• one or two minutes. After that, the watch returns to the Timekeeping Mode.

You can also change from the last signal or ERR screen to the normal timekeeping screen by pressing D .

Operation Guide 3347

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 normally exposed to bright light whenever possible.

•

Normally, the rechargeable batteries should not need replacement, but after very long use over a number of years, they may lose the ability to achieve a full charge.

Should you notice problems with getting the rechargeable batteries to a full charge, contact your dealer or CASIO distributor about having them replaced.

•

The rechargeable batteries should be replaced with CASIO-specified CTL1025 batteries only. Other rechargeable batteries can cause damage to 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 4 and if you should ever need to have the rechargeable batteries 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 batteries from going dead.

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the digital time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight

Saving Time.

The time calibration signal transmitted from Fort Collins includes 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 Fort

Collins signal.

•

The default DST setting is Auto DST ( A t ) whenever you select HNL , ANC ,

LAX , DEN , CHI , or NYC as your Home City code.

•

If you experience problems receiving the time calibration signal in your area, it is probably best to switch between Standard Time and Daylight Saving Time (summer time) manually.

To change the Daylight Saving Time (summer time) setting

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

2. Press C once and the DST setting screen appears.

3. Use D to cycle through the DST settings in the sequence shown below.

Radio-controlled Atomic Timekeeping Precautions

•

•

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

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.

•

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

±

15 seconds a month at normal temperature.

•

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, DST (summer time), and auto receive settings. The following are the initial factory defaults for these settings.

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 batteries replaced or when battery power drops to Level 4.

•

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 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

•

•

•

Illumination may be hard to see when viewed under direct sunlight.

Illumination automatically turns off whenever an alarm sounds.

Frequent use of illumination runs down the batteries.

Operation Guide 3347

Auto light switch precautions

•

The auto light switch is turned off automatically whenever battery power is at Level 3.

•

Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display. To avoid running down the batteries, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display.

•

Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the batteries.

More than 15 degrees too high

•

Illumination may not turn on if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground.

•

Illumination turns off after the preset illumination duration (see “To set the current digital time and date manually”), even if you keep the watch pointed towards your face.

•

Static electricity or magnetic force can interfere with proper operation of the auto light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

•

Under certain conditions, illumination may not turn on until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch.

•

You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
