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.
Warning Indicators
Warning indicators appear whenever any of the conditions described below
occur. Appearance of a warning indicator causes any measurement
operation that is currently underway to stop. Warning indicators appear in
the upper display, and this causes
--- to replace any direction or
temperature values on the display.
• There may be cause where the ERR or BAT message is cleared
once you change modes. In this case, you can continue using the watch
normally unless the error warning message reappears.
• Whenever there is a sensor malfunction, be sure to take the watch to an
authorized CASIO distributor or service center as soon as possible.
Abnormal Magnetic Field Indicator
This indicator appears whenever the watch has a problem
obtaining a correct direction reading. This condition could
indicate that the watch is within a very high magnetic field,
and so you should try moving to another location. Also,
see “Digital Compass Precautions” for further information
on conditions that cause errors.
Low Battery Indicator
This message indicates that batteries power is too low to
perform the measurement. It appears whenever batteries
power drops below a certain level, or when you try to use
this watch under very cold conditions (below about –10
° C).
If the BAT message appears because of use under cold conditions, it
should clear (and normal operation should return) after the watch is brought
back to normal temperature.
If batteries power is low (indicated
B A T appears under normal
temperatures), you should have the batteries replaced as soon as possible.
Note that replacement of the batteries causes all memory contents to be
cleared.
Sensor Malfunction Indicator
This message indicates malfunction of sensor circuitry.
Whenever a sensor malfunction initially occurs, the
ERR
messages flashes on the display. Note that calibrating the
Digital Compass may cause the
ERR message to appear.
In this case, the message does not indicate sensor
malfunction, and should be corrected if you re-calibrate
the Digital Compass.
Auto Return Operations
• After you perform an operation in any mode, pressing D returns to the
Timekeeping Mode.
• If you leave a screen with flashing digits on the display for two or three
minutes without performing any operation, the watch automatically saves
anything you have input up to that point and exits the setting screen.
Data and Setting Scrolling
The B and C buttons are used in various modes and screens 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.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping
Mode is also applied in the Navigation, World Time, and Alarm Modes.
Backlight Precautions
• The electro-luminescent panel loses illuminating power after very long
use.
• The illumination provided by the backlight may be hard to see when
viewed under direct sunlight.
• The watch will emit an audible sound whenever the display is illuminated.
This is caused by a transformer that vibrates when the EL panel lights
up. It does not indicate malfunction of the watch.
• The backlight automatically turns off whenever an alarm sounds.
Auto light switch precautions
• 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.
• The backlight turns off in about two seconds, even if you keep the watch
pointed towards your face.
•
The backlight may not light if the face of the watch is more than 15 degrees
off the parallel as shown below. Make sure that the back of your hand is
parallel to the ground.
• Static electricity or magnetic force can interfere with proper operation of
the auto light switch. If the backlight does not light, 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 the backlight may not light until about one second
or less after turn the face of the watch towards you. This does not
necessarily indicate malfunction of the backlight.
