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.

Radio-controlled Atomic Timekeeping

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

•This watch is designed to pick up the time calibration signals transmitted in Germany

(Mainflingen), England (Anthorn), the United States (Fort Collins), China (Shangqiu),

and Japan (Fukushima, 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 (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

“To set the time

and date manually” for more information about manual time settings.

•The U.S. time calibration signal can be picked up by the watch while in North

America. The term “North America” in this manual refers to the area that consists of

Canada, the continental United States, and Mexico.

•As of January 2009, 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.

•Using this watch in a country covered by a time calibration that is different from the

countries it supports may result in incorrect time indication due to local application of

summer time, etc.

To specify your Home City

1. In the Timekeeping Mode, hold down A for about five

seconds until the left dial hand points to T1 and the city

code flashes on the upper display. This is the setting

screen.

•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

“Important!” under “Time Calibration Signal Reception” and “Transmitters”.

•See the maps under “Approximate Reception Ranges” for information about the

reception ranges of the watch.

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.

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. Charging is reduced

significantly if the face is covered only

partially.

Solar cell

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.

•The current time and all other settings return to their initial factory defaults whenever

battery power drops to Level 5 (C) 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.

•The flashing indicator at Level 3 (L) 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 (C), all functions are disabled and settings return to their initial factory

defaults. Once the battery reaches Level 2 (M) after falling to Level 5 (C), reconfigure

the current time, date, and other settings.

•Display indicators reappear as soon as the battery is charged from Level 5 (C) to

Level 2 (M).

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

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

•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.

•Overuse of display illumination or the beeper can cause

the R (Recover) indicator to appear in the upper display,

which indicates that the watch is in the battery power

recovery mode. Face illumination, the alarm, the

countdown timer alarm, time signals, and all hand

operations are disabled in the power recovery mode.

The watch continues to keep time internally, so normal

timekeeping and function will resume as soon as battery

power recovers to normal levels, which is indicated

when the R indicator disappears.

•If R (recover) appears frequently, it probably means that

remaining battery power is low. Leave the watch in bright

light for some time 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

Charging Guide

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

•For details about the battery operating time and daily operating conditions, see the

“Power Supply” section of the Specifications.

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.

•Though the time calibration signals transmitted by the Fukushima and Fukuoka/

Saga, Japan transmitters include summer time data, summer time currently is not

implemented in Japan (as of 2009).

•The default DST setting is Auto DST ( ) whenever you select LIS, LON, MAD,

PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, 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.

Radio-controlled Atomic Timekeeping Precautions

•Strong electrostatic charge can cause the time setting to be thrown off.

•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 the time with the precision noted in “Specifications”.

•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 and DST

(summer time) settings.

•The Home City setting reverts to the initial default of TYO (Tokyo) whenever the

battery power drops to Level 5 (C) 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 the watch with a flashing setting on the display for two or three minutes

without performing any operation, the watch automatically exits the setting screen.

•The watch will return to the Timekeeping Mode automatically if you do not perform

any operation for two or three minutes in the Alarm Mode.

High-Speed Movement

•The D and B buttons are used to change the hand setting in various setting

modes. In most cases, holding down these buttons will start high-speed movement

of the applicable hand(s).

Initial Screens

When you enter the 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 when battery power drops to Level 5 (C).

•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.

Illumination Precautions

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

•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

(C).

•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.

•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.

More than 15 degrees

too high

•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.
