Reference
This section contains more detailed and technical information about watch
operation. It also contains important precautions and notes about the various
features and functions of this watch.
Auto Return Features
•
The watch returns to the Timekeeping Mode automatically if you do not
perform any button operation for two or three minutes in the Data Recall,
Alarm, Receive, Digital Compass, or Barometer/Thermometer Mode.
•
If you do not perform any button operation while in the Altimeter Mode, the
watch returns to the Timekeeping Mode automatically after nine or 10
hours.
•
If you leave a screen with flashing digits on the display for two or three
minutes without performing any operation, the watch exits the setting
screen automatically.
Scrolling
The
A
and
C
buttons are used on the setting screen to scroll through data
on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Sensor Malfunction Indicator
Subjecting the watch to strong impact can cause sensor malfunction or
improper contact of internal circuitry. When this happens,
ERR
(error) will
appear on the display and sensor operations will be disabled.

Measurement
•
If
ERR
appears while a measurement operation is being performed in a
sensor mode, restart the measurement. If
ERR
appears on the display
again, it can mean there is something wrong with the sensor.
•
Even if battery power is at Level 1 or Level 2, the Digital Compass Mode,
Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled
if there is not enough voltage available to power it sufficiently. In this case,
ERR
will appear on the display. This does not indicate malfunction, and
sensor operation should resume once battery voltage returns to its normal
level.
•
If
ERR
keeps appearing during measurement, it could mean there is a
problem with the applicable sensor.
Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.
Power Saving
When turned on, Power Saving enters a sleep
state automatically whenever the watch 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.
•
There are actually two sleep state levels:
“display sleep” and “function sleep”.

Operation
Display is off, but all functions are
enabled.
All functions are disabled, but
timekeeping is maintained.
•
Wearing the watch inside the sleeve of clothing can cause it to enter the
sleep state.
•
The watch will not enter the sleep state while the digital time is between
6:00 AM and 9:59 PM. If the watch is already in the sleep state when the
digital time reaches 6:00 AM, however, it will remain in the sleep state.
•
The watch will not enter the sleep state while it is in the Digital Compass,
Barometer/Thermometer, Altimeter, Receive, Countdown Timer, or
Stopwatch Mode. When the watch is left in any mode besides the
Countdown Timer and Stopwatch Mode, the watch will return to the
Timekeeping Mode automatically after a specific amount of time. Then if left
in the dark for the elapsed time indicated in the table above, the watch will
enter the sleep state.
To recover from the sleep state
Perform any one of the following operations.
•
Move the watch to a well-lit area. It can take up to two seconds for the
display to turn on.
•
Press any button.
•
Angle the watch towards your face for reading.
To turn Power Saving on and off
1. In the Timekeeping Mode, hold down
E
until
the city code starts to flash, which indicates
the setting screen.
2. Press
D
nine times until the Power Saving
on/off screen appears.
3. Press
C
to toggle Power Saving on (
ON
) and
off (
OFF
).
4. Press
E
to exit the setting screen.
•
The Power Saving on indicator (
PS
) is on the
display in all modes while Power Saving is
turned on.

Radio-controlled Atomic Timekeeping Precautions
•
Strong electrostatic charge can result in the wrong time being set.
•
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, 2001 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 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 Home City setting reverts to the initial default of
BER
(Berlin)
whenever the battery power level drops to Level 5 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 the 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
(Rugby). The following tables show the reception priority for the European
signals.
When PAR, BER, or ATH is selected as the Home City code:
When LON is selected as the Home City code:
In this case:
The first signal search
operation after the Home City
code has been changed
The second and
subsequent signal searches
The watch does this:
1. Checks the Mainflingen signal first.
2. If the Mainflingen signal cannot be
received, checks the Rugby signal.
1. Checks the signal of the transmitter of the first
receive operation (Rugby or Mainflingen).
2. If the checked signal cannot be received,
checks the other signal.
The watch does this:
1. Checks the Rugby signal first.
2. If the Rugby signal cannot be received,
checks the Mainflingen signal.
1. Checks the signal of the transmitter of the first
receive operation (Rugby or Mainflingen).
2. If the checked signal cannot be received,
checks the other signal.
In this case:
The first signal search
operation after the Home City
code has been changed
The second and
subsequent signal searches
4. When the setting you want is selected, press
E
to exit the setting screen.
•
The
DST
indicator appears to indicate that Daylight Saving Time is turned
on.
