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.

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.

Important!

• 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 “Home

City Codes and Transmitters”.

• Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HKG (Hong Kong), BJS (Beijing), HNL (Honolulu), and

ANC (Anchorage). For details about turning on auto receive for these city codes, see

“To turn auto receive on and off”.

• You can disable time signal reception, if you want. See “To turn auto receive on and off” for more information.

• See the maps under “Approximate Reception Ranges” for information about the reception ranges of the watch.

• If you are in an area that does not use Daylight Saving Time (summertime), turn off the DST setting.

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 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.

Operation Guide 3063

• 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 one 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. 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.

Note

• When a calibration time is reached, the watch will receive the 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, or while a countdown operation is in progress.

• 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 takes from one to 14 minutes to receive the time calibration signal whenever a calibration time is reached. Avoid performing any button operation within

14 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 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 Level Indicator

The level 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.

Level indicator

Weak

(Level 0)

Strong

(Level 3)

• Use the level indicator as a guide for checking signal strength and for finding the best level for the watch during signal receive operations.

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

• Following reception of the time calibration signal and calibration of the watch’s time setting, the “signal received” indicator (RCVD) will remain on the display in all modes.

• The signal received indicator (RCVD) 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 signal received indicator (RCVD) indicates that at least one of the auto calibration signal receive operations was successful, even if other receive operations failed.

Illumination

Auto light switch indicator

The watch has an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. The watch’s auto light switch illuminates the display automatically when you angle the watch towards your face.

• The auto light switch must be turned on (indicated by the auto light switch indicator) for it to operate.

• See “Illumination Precautions” for other important information.

To turn on illumination manually

In any mode, press B to illuminate the display for about one second.

• The above operation turns on illumination regardless of the current auto light switch setting.

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

EL 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.

Moving the watch to a position that is parallel to the ground and then tilting it towards you at more than 40 degrees causes illumination to turn on.

• Wear the watch on the outside of your wrist.

Parallel to ground

More than

40°

Warning!

• Always make sure you are in a safe place whenever you are reading 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 on 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 (except when a setting screen is on the display), hold down

B for about three seconds to toggle the auto light switch on (A.EL displayed) and off

(A.EL not displayed).

• The auto light switch indicator remains in all modes while the auto light switch is turned on.

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.

Solar cell

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 only partially covered.

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 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.

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.

• The time calibration signals transmitted from Fukushima and Fukuoka/Saga (Japan) do not include summer time data.

• The default DST setting is Auto DST (

) whenever you select LIS, LON, MAD,

PAR, ROM, BER, STO, ATH, MOW, HKG, BJS, TPE, SEL, TYO, HNL, ANC, YVR,

LAX, YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, or YYT as your Home City code.

• 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.

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 and the DST setting screen appears.

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

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.

Button Operation Tone

The button operation tone sounds any time you press one of the watch’s buttons. You can turn the button operation tone on or off as desired.

• Even if you turn off the button operation tone, the alarm, hourly time signal, and Countdown Timer Mode alarm all operate normally.

Mute indicator

To turn the button operation tone on and off

In any mode (except when a setting screen is on the display), hold down C to toggle the button operation tone on (mute indicator not displayed) and off (mute indicator displayed).

• Since the C button is also the mode change button, holding it down to turn the button operation tone on or off also causes the watch’s current mode to change.

• The mute indicator ( ) is displayed in all modes when the button operation tone is turned off.

Power Saving Function

When turned on, the Power Saving function enters a sleep state automatically whenever the watch is left in an area where it is dark for a certain period. The table below shows how watch functions are affected by the Power

Saving function.

• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.

• The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

• The watch will not enter the sleep state while it is in the Stopwatch Mode or

Countdown Timer Mode.

To recover from the sleep state

Perform any one of the following operations.

• Move the watch to a well-lit area.

• Press any button.

• Angle the watch towards your face for reading.

To turn Power Saving on and off

1. In the Timekeeping Mode, hold down A until the city ll l l ll lll l l l l ll l ll 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 ( ) and off

( ).

4. Press A to exit the setting screen.

• The Power Saving indicator (PS) 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 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 will exit the setting screen automatically.

Scrolling

The B and D buttons are used in various modes and setting screens to scroll through data. 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 Atomic Timekeeping Precautions

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

• The time calibration signal is bounced 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 a 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.

• 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.

Operation Guide 3063

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 displayed automatically 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 or when battery power drops to

Level 5.

• The times for the Timekeeping Mode and all the city codes of the World Time Mode are calculated in accordance with each city’s UTC differential.

• The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England and the time zone where a city is located.

• “UTC” is the abbreviation for “Universal Time Coordinated”, which 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.

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 (P) 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

• The electro-luminescent panel that provides illumination loses power after very long use.

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

• The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the battery.

Auto light switch precautions

• The auto light switch is turned off automatically whenever battery power is at Level 4.

• 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 battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination.

• 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 battery.

• 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 in about one second, 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.
