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.

••••• This watch does not have a city code that corresponds to the UTC offset of

–3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

Keep the watch exposed to bright light

l l

Bright light l l l l l l

Solar cell

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. Even if the face of the watch is blocked only partially from light, charging will be reduced significantly.

• 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.

Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.

• Supported time calibration signals: Germany (Mainflingen), England (Anthorn), United

States (Fort Collins), China (Shangqiu), and Japan (Fukushima or 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, which is 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 “Configuring

Time and Date Settings Manually” for more information about manual time settings.

To specify your Home City

1. In the Timekeeping Mode, keep A depressed (for about five seconds) as the second hand moves to the last signal reception result (“Y” or “N”), then to “READY”

30

3

(or “R” for some models), and then to the city code of the currently selected Home City.

• This indicates the city code setting mode.

2. Use D to move the second hand clockwise to the city

City code

Second hand code you want to use as your Home City.

• For information about the Home City, see “Home City

Codes and Transmitters”. The watch will receive the time calibration signal of the transmitter of the selected city code.

3. After the Home City setting is the way you want, press A to return to the

Timekeeping Mode.

• Normally, your watch should show the correct time as soon as you specify your

Home City code. If it does not, it should adjust automatically after the next auto receive operation. You also can perform manual receive or you can set the time manually.

• Even if the time calibration signal is received correctly, there are some times when the analog hands may not indicate the correct time. If this happens, use the procedures under “Auto Hand Home Position Correction” to check the home positions of the hands, and make adjustments as required.

Home City Codes and Transmitters

• The time calibration signal the watch will attempt to pick up depends on its current

Home City code setting as shown below. If you use the watch in Japan or Europe

(each of which has two different transmitter locations), it will try to receive the time calibration signal from one of the transmitters in your current location. If it cannot receive the signal, it will then try to receive the time calibration signal from the other transmitter.

• 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.

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 watch will adjust the DST setting automatically when it receives a time calibration signal while any one of the following city codes is selected as the Home

City.

LON, PAR, ATH, TYO, ANC, LAX, DEN, CHI, NYC

• The watch will not adjust the DST setting automatically while either of following city codes is selected as the Home City. In this case, you will need to change between standard time and daylight saving time manually.

HKG, HNL

• For information about the DST setting, see “To set your Home City time”.

• As of March 2008, 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.

• If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time (summer time) manually. For more information, see “Home City and DST”.

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.

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 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.

About 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. 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 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 receive the signal easily.

• Remember that reception of the calibration signal depends on the current time in the

Timekeeping Mode.

To perform manual receive

1. Place the watch on a stable surface so its 12 o’clock side is facing towards a window.

2. In the Timekeeping Mode, hold down A for about two

Auto Hand Home Position Correction

Strong magnetism or impact can cause the hands and/or day setting to be off, even if the watch is able to perform the signal receive operation. Auto hand home position correction corrects the hand position automatically.

• Auto correction is performed in the Timekeeping Mode only. However, auto correction is never performed while a countdown timer operation is in progress.

• The auto correction operation corrects the positions of the second, minute, and hour hands. Home position correction of the dial hands and day must be performed manually, using the procedure under “Manual Home Position Correction”.

• Each hour, the watch performs automatic correction of the hand positions from –55 minutes to +5 minutes.

• You also can trigger the auto hand home position correction operation manually, if you want. See “To trigger the auto hand home position correction operation manually” for more information.

• The auto hand home position correction operation can take up to three and a half minutes to complete.

• If hand positions are off by one hour or more, correct them using the procedure under “To trigger the auto hand home position correction operation manually” or

“Manual Home Position Correction”.

To trigger the auto hand home position correction operation manually

• Perform the following procedure when the time setting is off.

In the Timekeeping Mode, hold down D for about six seconds until the second hand completes one full

30 revolution.

• Though the watch will beep and second hand will stop momentarily about three seconds after you hold down

D, do not release the button yet. Wait until the second hand completes a full revolution before you release D.

• To interrupt an ongoing correction operation and return to the Timekeeping Mode, press D again.

• If you release D when the watch beeps and the second hand stops the first time

(after about three seconds) in the above operation, the watch will enter the manual home position correction mode, which is described under “Manual Home Position

Correction”. If this happens, press A to return to the Timekeeping Mode and then perform the above operation again.

The manually triggered auto home position correction operation performs the following two steps.

1. The hands will move automatically in order to determine the home positions of the watch.

2. After the hand home positions are determined, the watch will return to normal timekeeping automatically. This completes the correction operation.

Manual Home Position Correction

Strong magnetism or impact can cause the hands and/or day setting to be off, even if the watch is able to perform the signal receive operation. If this happens, perform the following home position correction procedure.

• Hand home position correction is not required if the time and day settings are correct.

• You also can use auto hand home position correction to correct the home positions of the second, minute, and hour hands.

1. In the Timekeeping Mode, hold down D for about three seconds until the watch beeps and the second hand stops. Release D at this time.

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. Even if the face of the watch is blocked from light only partially, charging will be reduced significantly.

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.

• The special rechargeable (secondary) battery used by your watch is not intended to be removed or replaced by you. Use of a rechargeable battery other than the special one specified for this watch can damage the watch.

• The current time and all other settings return to their initial factory defaults whenever the watch is left uncharged for about one week after battery power drops to Level 3, and when you have the battery replaced.

• Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Hand Movement Function Status

Normal.

• Second hand jumps every 2 seconds.

• Day changes to home position.

• Second hand stopped.

• Hour and minute hands stopped at 12 o’clock.

All functions enabled.

Beeper and time calibration signal reception disabled.

All functions disabled.

• The second hand jumping every two seconds (Level 2) indicates that battery power is quite low. Expose the watch to light as soon as possible to charge the battery.

• When battery power is at Level 2, time calibration signal reception is disabled.

• When power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently during this period, the analog hands will move automatically to the correct setting and normal timekeeping will resume. If the watch is left uncharged for about one week after battery power drops to Level 3, the current time and all other settings return to their initial factory defaults.

• Alarm operation can cause hand movement to stop due to a sudden temporary drop in power. This does not indicate malfunction, and normal operation will resume when the watch is exposed to light. Though hand movement stops, timekeeping continues internally, and the hands will be adjusted to the correct setting when normal operation returns.

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.

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 five 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)

Reference

This section contains more detailed and technical information about watch operation.

It also contains important precautions and notes about the various features and functions of this watch.

Auto Return Features

• If you do not perform any operation for about two or three minutes in the Alarm

Mode, in the current time setting mode, or in the hand/day home position correction mode, the watch will return to the Timekeeping Mode automatically.

• If you do not perform any operation for about two or three minutes while a setting mode is selected, the watch will exit the setting mode automatically.

High-Speed Movement

• In most cases when configuring settings, holding down a button will start high-speed scrolling of the applicable setting.

• High-speed movement of hands and day will continue until you press any button.

Radio-controlled Atomic 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 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 will not 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 time with the precision noted in “Specifications”.

Timekeeping

• 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 normally should be no reason to change it. Note, however, that if the watch is left uncharged for about one week after battery power drops to Level 3, the current time and all other settings return to their initial factory defaults.

• The date will change automatically when the current time reaches midnight. The date change at the end of the month may take more time than normal.

• The current time for all time zones in the Timekeeping Mode and World Time Mode is calculated in accordance with the Coordinated Universal Time (UTC) offset of each zone, based on your Home Time Zone time setting.

• 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.
