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.

Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any
damage or loss suffered by you or any third party arising through the use of this
product or its malfunction.

Keep the watch exposed to bright light

Bright Light

Solar cell

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 even 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.

The actual level at which some functions are disabled depends on the watch model. •
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 about 8 hours 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.

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.
Using this watch in a country covered by a time calibration signal that is different •
from the countries it supports may result in incorrect time indication due to local
application of summer time, etc.

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 “Home City Code” 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,
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 pointing 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

Proper signal reception can be difficult or even impossible under the conditions •
listed below.

Inside or
among
buildings

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.

reception will be 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.
As of July 2010, 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.

About 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, remaining auto
receive operations are not performed. The reception schedule (calibration times)
depends on your currently selected Home City, and whether standard time or Daylight
Saving Time is selected for your Home City.

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 14 minutes everyday when •
the time in the Timekeeping Mode reaches a calibration time. Do not perform any
button operation within 14 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 •
your Home City, as kept in the Timekeeping Mode.
