If the digital dials of the watch are blank...
Power saving indicator
If the Power Saving indicator (
) is flashing on the top
dial, it means that the digital dials are blank because the
watch’s Power Saving function has turned them off to
conserve power. Power Saving automatically turns off the
digital dials and enters a sleep state whenever your watch
is left for a certain period in an area where it is dark. If the
watch is kept in the dark for a longer period, the analog
hands will also stop moving after a few days.
• The initial factory default setting is Power Saving on.
• The watch will recover from the sleep state if you move it
to a well-lit area, if you press any button, or if you angle
the watch towards your face for reading.
• See “Power Saving Function” for more information.

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 five
times a day at midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. For more
information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration signal reception 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.

Configuring Auto Receive Settings
You can use the procedure in this section to configure the watch to receive the signal
of a specific transmitter, or to automatically receive from the transmitter whose signal
is strongest. You can also turn off auto receive, if you want.
• Note that you can perform the following procedure only when LON, BER, or PAR
is selected as your Home City.
llll

Mainflingen
llll
• This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. Signal reception is possible
within the area represented by a circle with a radius of about 1,500 kilometers.
• 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.
• See the information under “Signal Reception Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches midnight, 1:00
a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will
also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled
auto receive operations are successful.
Note
• Auto receive is performed only if the watch is in the Timekeeping Mode or World
Time Mode when one of the calibration times is reached. It is not performed if a
calibration time is reached while an alarm is sounding, or while you are configuring
settings (while a setting is flashing in a digital dial).
• 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 easily receive the signal.
• When auto receive is turned on, the watch receives the calibration signal for two to
seven minutes everyday when the time in the Timekeeping Mode reaches each of
the five calibration times. Do not perform any button operation within seven minutes
before or after any of the five calibration times. Doing so can interfere with correct
calibration.
• Remember that reception of the calibration signal depends on the digital time kept
by the Timekeeping Mode. Reception will be performed whenever the Timekeeping
Mode time reaches one of the five calibration times, regardless of whether or not the
Timekeeping Mode time is actually the correct time.
• When two, three, four, or five receptions are successful, the watch uses the data of
the last reception for calibration. 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
(Level 0)
ll
500 kilometers
Strong
(Level 3)
• 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 reception.
• The Level 3 receiving indicator remains displayed on the top dial in all modes
following reception of the time calibration signal and calibration of the watch’s time
setting. The Level 3 receiving indicator is not displayed on the top dial if signal
reception was unsuccessful or after manual adjustment of the current time setting.
• The Level 3 receiving indicator indicates that at least one of the five calibration
signal receive operations was successful. Note, however, that the Level 3 receiving
indicator is cleared at 3:00 a.m. each day.
To perform manual receive

o’clock side) is facing towards a window.
2. In the Timekeeping Mode, hold down D for about two
seconds until the watch beeps.
3. After you release D, the bottom dial will alternate
between the current time and date, and the letters
RC!. This indicates that signal reception is in
progress.
• Time calibration signal reception normally 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 while time calibration signal reception is in
progress.
• After signal reception is complete, the bottom dial changes to the last signal screen.
Note
• To interrupt a reception and return to the Timekeeping Mode, press D.
• If reception is unsuccessful, the message ERR appears in the bottom dial for about
one or two minutes. After that, the watch returns to the Timekeeping Mode.
• You can also clear the ERR message by pressing D.
3. Use D to cycle through the settings shown below, until the one you want to use is
displayed in the bottom dial.

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 special rechargeable batteries to store power produced by the solar
cell, so regular battery replacement is not required. However, after very long use, the
rechargeable batteries may lose its ability to achieve a full charge. If you experience
problems getting the special rechargeable batteries to fully charge, contact your
dealer or CASIO distributor about having them replaced.
• Never try to remove or replace the watch’s special batteries yourself. Use of the
wrong type of batteries can damage the watch.
• All data stored in memory is deleted, and the current time and all other settings
return to their initial factory defaults whenever battery power drops to Level 4 and if
you should ever need to have the rechargeable batteries 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
batteries from going dead.

Auto Return Features
• If you leave the watch in the Alarm or Hand Setting Mode for two or three minutes
without performing any operation, it automatically returns to the Timekeeping Mode.
• If you leave the watch with a flashing setting in a dial for two or three minutes without
performing any operation, the watch automatically exits the setting screen.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data. In most cases, holding down these buttons during a scroll operation
scrolls through the data at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
Radio-controlled 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 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.
• 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 automatically update the date and day of the week 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.
• 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, DST (summer
time), and auto receive settings. The following are the initial factory defaults for these
settings.

Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. You can select either one of the
transmitters, or you can configure the watch to automatically select the transmitter that
has the strongest signal.
• The following explains how the watch determines which transmitter it should check
first while the watch is configured for auto transmitter search (AvtA).

Power Saving Function
When turned on, the Power Saving function automatically
puts the watch into a sleep state whenever it is left for a
certain period in an area where it is dark. The table below
shows how watch functions are affected by Power Saving.
In this case:
The watch does this:
The first signal auto search operation

• Move the watch to a well-lit area.
• Press any button.
• Angle the watch towards your face for reading.
ll
Daylight Saving Time (summer time) advances the digital 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 Rugby and Mainflingen 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 received time signal.
• The default DST setting is Auto DST (AvtA) whenever you select BER, PAR,
LON, or ATH as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.

back cover. The Module number (3360 or 3361) is
engraved inside the box on the back cover.
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 day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
• 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 after you have the watch’s batteries replaced or when battery power drops
to Level 4.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
* UTC is the world-wide scientific standard of timekeeping. It is based upon carefully
maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.
The reference point for UTC is Greenwich, England.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also

• Based on data as of December 2003.
Illumination Precautions
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination runs down the batteries.
Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is at Level 3.
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of
your arm can cause frequent activation of the auto light switch and illumination of the
digital dials. To avoid running down the batteries, turn off the auto light switch
whenever engaging in activities that might cause frequent illumination.
• Note that wearing the watch under your sleeve while the auto light switch is turned
on can cause frequent illumination of the digital dials and can run down the
batteries.
More than 15 degrees
too high
• 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 current digital time and date
manually”), 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.
• 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.
