• The first thing you should do after purchasing this watch is to set your Home City, which is the city where you will use the watch normally. For more information, see “To set your Home City” below.

• When using the watch outside of the range of the transmitter in Fort Collins, you need to adjust the time manually as required. See “Timekeeping” for information about manual settings.

To set your Home City

City code

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 can also perform manual receive or you can set the time manually.

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

This watch receives a time calibration signal and updates its time setting accordingly. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.

• This watch is designed to pick up the time calibration signal transmitted from Fort Collins, Colorado (USA). Reception is possible within North America*.

The term “North America” in this User’s Guide refers to the

area that consists of Canada, the continental United States, and Mexico.

Current Time Setting

This watch adjusts its time setting automatically in accordance with a time calibration signal. You can also perform a manual procedure to set the time and date, when necessary.

1. In the Timekeeping Mode, hold down A until the city

code starts to flash, which indicates the setting screen.

2. Use D(east) and B(west) to select the city code you

want to use as your Home City.

• The following are the city codes for major cities in

North America.

: Los Angeles, San Francisco, Las Vegas,

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 three times a day at midnight, 1:00 a.m., and 2:00 a.m. 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. Make sure there are no metal objects nearby.

• The watch should not be on its side or facing the wrong 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 or office equipment, or a mobile phone

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

Operation Guide 2913

• Signal reception is normally better at night than during the day.

• Time calibration signal reception takes from two to six minutes. Take care that you

do not perform any button operations or move the watch during this time.

600 miles

• 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 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 Receive Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

When auto receive is turned on, the watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches midnight, 1:00 a.m. and 2:00 a.m. (calibration times). If both the 1 o’clock and 2 o’clock signal receptions are not successful, the watch will try to receive the signal again at the top of each hour up until 5:00 a.m. or until one more reception is successful.

Note

• Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or if a setting screen (a screen with a flashing setting) is 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 receive the signal easily.

• When auto receive is turned on, the watch receives the calibration signal for two to six minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within six 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 is actually the correct time.

• If more than one auto receive is successful, the watch uses the data from the last successful receive to adjust settings. 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

• 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 receive operations.

• Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 4 receiving indicator will remain on the display in all modes. The Level 4 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

• The Level 4 receiving 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 4 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 4 receiving indicator is cleared from the display at 1:00 a.m. each day.

Illumination

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

Auto light switch indicator

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.

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 any mode, hold down L for about two seconds to toggle the auto light switch on (auto light switch indicator displayed) and off (auto light switch indicator not displayed).

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

In any mode, press L to illuminate the display.

• You can specify 1.5 seconds or 2.5 seconds as the illumination duration. See “To set the time and date” for more information.

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

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.

• 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 4 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.

Battery Power Indicator and Recover Indicator

The battery power indicator shows you the current power level of the rechargeable battery.

Battery power indicator

Recover indicator

• The flashing charge indicator ( CHG ) 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 4, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 3 (indicated by the flashing charge indicator) from Level 4. You will not be able to configure any of the other settings until the battery reaches Level 2 (no charge indicator) after dropping to Level 4.

•

Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to show a reading that is momentarily higher than the actual battery level. The correct battery power indicator should appear after a few minutes.

• If you use the light or alarms a number of times during a short period, the recover indicator (RECOV) appears and the following operations become disabled until battery power recovers.

Illumination Beeper tone

After some time, battery power will recover and the recover indicator will disappear, indicating that the above functions are enabled again.

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

Charging Guide

After a full charge, timekeeping remains enabled for up to about 11 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.

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 is 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 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.

• 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.

• 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.

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.

• 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 time and date”), 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.
