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 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.

Dis-

charge

Battery charges in the light. Battery discharges in the dark.

• Frequent display illumination can run down the battery quickly and require charging.

The following guidelines give an idea of the charging time required to recover from a

single illumination operation.

Approximately 5 minutes exposure to bright sunlight coming in through a window

Approximately 50 minutes exposure to indoor fluorescent lighting

• Be sure to read “Power Supply” for important information you need to know

when exposing the watch to bright light.

If the display of the watch is blank...

If the display of the watch is blank, it means that the watch’s Power Saving function

has turned off the display to conserve power.

• See “Power Saving Function” for more information.

Radio-controlled Timekeeping

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 Rugby, England and the signal

from Mainflingen, Germany.

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.

• 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”.

• When using the watch in an area that is outside of the range of the transmitters in

Rugby and Mainflingen, you need to adjust the time manually as required. See

“Timekeeping” for information about manual settings.

To set your Home City

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

code starts to flash, which indicates the setting screen.

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

want to use as your Home City.

• The following are the city codes for major cities in the

Western Europe time zones.

LIS

: Lisbon

LON: London

BCN: Barcelona

MAD: Madrid

PAR: Par is

MIL: Milano

ROM: Rome

BER: Berlin

STO: Stockholm

ATH: Athens

3. Press A to exit the setting screen.

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 also can 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.

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.

Make sure there are no metal objects nearby.

Resin Band

• 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.

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

• Time calibration signal reception takes from two to five 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.

Operation Guide 3041

• This watch is designed to receive the time calibration signal transmitted from Rugby,

England and the signal from Mainflingen, Germany.

• At distances further than about 500 kilometers from a transmitter, signal reception

may not be possible during certain times of year or times of day. Radio interference

may also cause problems with reception.

Reception Ranges

• 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.

• See the information under “Signal Receive Troubleshooting” if you experience

problems with time calibration signal reception.

About 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. The start times of the auto receive operations depend

on the current Home City and DST settings.

• 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 while a

setting screen (a screen with a flashing setting) is on the display.

• 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.

• When auto receive is turned on, the watch receives the calibration signal for two to

five minutes everyday when the Timekeeping Mode time reaches each of the

calibration times. Do not perform any button operation within five 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 actually is the correct time.

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.

• 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.

• Time calibration signal reception takes from two to five

minutes, but in some cases it can take as long as 12

operations or move the watch during this time.

• After signal reception is complete, the display of the

watch changes to the Last Signal screen.
