Adjusting the Home Positions

If the time and date settings are wrong even after the time calibration signal is

received normally, use the following procedure to adjust their home positions.

To adjust the home positions

1. Enter the Home Position Adjustment Mode.

• If the home position of the second hand is currently

correct, it will move to the 12 o’clock position.

2. While in the Home Position Adjustment Mode, hold

down A for about five seconds. This will cause the

second hand to make one revolution and stop at its

current home position.

• The analog hands do not keep time during home

position adjustment.

3. Check the position of the second hand.

• The second hand home position is correct if it is

pointing at 12 o’clock.

• If the second hand is not pointing at 12 o’clock, it

means that its home position is off. If this happens,

press B to move the second hand clockwise in one-

second steps, until it points at 12 o’clock.

4. Press A to advance to hour and minute hand home

position adjustment.

• If current hour and minute hand alignment is correct,

they will both move to 12 o’clock.

5. Check the position of the hour and minute hands.

• If the hour and minute hands are not pointing at 12

o’clock, it means that their home position is off. If this

happens, press B to move the hour and minute

hands clockwise in 10-second steps, until they point

at 12 o’clock.

• You can change the hour and minute hand movement

direction to counterclockwise by pressing A. After

that, each press of B will move the hour and minute

hands counterclockwise in 10-second steps.

date is changing, and the hour and minute hands are

moving.

• To return to the Timekeeping Mode, press B.

• After you complete the home position adjustment procedure, place the watch in a

location that allows good time calibration signal reception, and then perform a

manual receive operation. See “To perform manual receive” for more information.

Timekeeping

Use the Timekeeping Mode to set and view the current

time and date. This section also explains how to set the

current date and time manually.

• If you become confused and lose your way during the

following procedures, simply put the watch down and do

not perform any button operation for two or three

minutes. This will cause the watch to enter the

Timekeeping Mode (indicated by normal one-second

movement of the second hand) automatically. After that,

you can try performing the manual setting procedure

again from the beginning.

• All of the operations in this section are performed in the

Timekeeping Mode, which you enter by pressing B.

To set the time and date manually

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

seconds.

•

This will cause the second hand to move to 5 o’clock, 6

o’clock, 7 o’clock, or 8 o’clock, depending on the currently

selected GMT differential setting. This is the setting mode.

• The GMT differential value indicates the time difference in

hours between Greenwich Mean Time and the currently

selected time zone.

•

The hour and minute hands do not move in the setting mode.

Use B (–).

Press B.

3. Select the setting you want to change, and then use B to change it as shown

below.

• Pressing B while the seconds setting is selected will cause the second hand to

move to 00 seconds. This also advances the minute by one, resets the seconds

count to 00, and exits the setting mode automatically.

• If you want to change the year, month, and day setting after resetting the

seconds, re-enter the setting mode from step 1.

• When setting the day, the watch automatically will skip days

(30 and 31) that are not included in the currently selected

month. If you can’t select 30 or 31 when you want to, check

to make sure that the proper month is selected.

4. After setting the 1’s digit of the year, press A to exit the

setting mode.

•

This will cause the hands to move to the current time, and

resume normal movement.

• Make sure that you set the time correctly as AM or PM (as

indicated by the second hand) when setting the time. The

second hand will move between AM and PM any time the

hour hand moves past 12 o’clock while you are setting the

time.

Illumination

An LED (light-emitting diode) illuminates the face of the

watch for easy reading in the dark. The watch’s auto light

switch automatically illuminates the face when you angle

the watch towards your face.

• The auto light switch must be turned on for it to operate.

• See “Illumination Precautions” for other important

information.

To illuminate the face of the watch

In the Timekeeping Mode (except for the setting mode),

press A to illuminate the face of the watch about for 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 the face to illuminate about for one second,

whenever you position your wrist as described below in any mode. Note that this

watch features a “Full Auto LED Light”, so the auto light switch operates only when

available light is below a certain level. It does not illuminate the face 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 face

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 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 Receive Result Mode, hold down A for about three seconds to toggle the auto

light switch on and off.

• You can check the current auto light switch on/off setting by pressing A while in the

Receive Result Mode. If the face of the watch illuminates when you press A, it

means that the auto light switch is on. The auto light switch is off if the face does not

illuminated when you press A.

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. Even if the face of the watch

is blocked from light only partially,

charging will be reduced significantly.

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. 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.

• 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 3 and when you have the battery replaced.

• Keep the watch in an area normally exposed to bright light when storing it for long

periods. This helps to keep the rechargeable battery from going dead.
