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

The electricity generated by the solar cell of the

Bright Light

Solar cell 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.

• 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 “Time Calibration Signal Reception” and “Transmitters”.

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

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

• Under factory default settings, auto receive is turned off for all of the following city codes: MOW (Moscow), HNL (Honolulu), and ANC (Anchorage). For details about turning on auto receive for these city codes, see “To turn auto receive on and off”.

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.

• 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.

• The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below.

Operation Guide 3150

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 seven minutes everyday when the time in the Timekeeping Mode reaches a calibration time. Do not perform any button operation within seven 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 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 Signal Strength Indicator

The signal strength 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. The signal strength indicator is displayed while an auto or manual receive operation is in progress.

Signal strength indicator

lllll ll l llll lll

Weak

(Level 1)

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 signal strength indicator to indicate signal strength.

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

• Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 3 signal strength indicator will remain on the display in all modes. The Level 3 signal strength indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

• The Level 3 signal strength indicator 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 Level 3 signal strength indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 3 signal strength indicator disappears from the display each day when the first auto receive operation of the day is performed.

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.

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.

Parallel to ground

More than

40

°

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 L for about three seconds to toggle the auto light switch on (A.EL displayed) and off (A.EL not displayed).

• The auto light switch on indicator (A.EL) is on the display 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 covered only partially.

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.

• 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 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.

indicator at Level 3 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, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.

• The watch’s Home City code setting will change automatically to TYO

(Tokyo) whenever the battery drops to Level 5. 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.

• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.

• 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.

l l l l l ll ll l l ll l l l ll

Recover indicator

• Performing illumination, or beeper operations during a short period may cause

(recover) to appear on the display. Illumination, alarm, countdown timer alarm, and hourly time signal will be disabled until battery power recovers.

After some time, battery power will recover and

(recover) will disappear, indicating that the above functions are enabled again.

• If

(recover) appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

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

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.

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.

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 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 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 Home City setting reverts to the initial default of

TYO (Tokyo) whenever the battery power level drops to Level 5 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, PAR, ROM, BER, STO, ATH, and MOW).

Auto Return Features

• If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.

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 at high speed.

Initial Screens

When you enter the Rally Mode, Recall Mode, World Time Mode, or Alarm

Mode, the data you were viewing when you last exited the mode appears first.

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 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 Coordinated Universal Time

(UTC) for each city, based on your Home City time setting.

World Time

• The seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode.

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.

9

Operation Guide 3150

Auto light switch precautions

• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life. If you want to wear the watch on the inside of your wrist, turn off the auto light switch feature.

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 a preset amount of time (1.5 or 3 seconds), 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 toward 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.
