ALARM FUNCTIONS
When the Daily Alarm is on, the alarm sounds
for 10 seconds at the preset time each day.
Press any button to stop the alarm after it starts
to sound.
When the Hourly Time Signal is on, the watch
beeps every hour on the hour.
Setting the alarm time
1. Use C to enter the Alarm Mode.
2. Hold down A until the hour digits flash on the display. The hour digits
flash because they are
selected
.
• At this time, the alarm is automatically switched on.
3. Press C to change the selection in the following sequence.
4. Press D to increase the selection or B to decrease it. Holding down
either button changes the selection at high speed.
• The format (12-hour and 24-hour) of the alarm time matches the format you
select for normal timekeeping.
• When setting the alarm time using the 12-hour format, take care to set the
time correctly as morning (A) or afternoon (P).
5. After you set the alarm, press A to return to the Alarm Mode.
Turning the Daily Alarm and Hourly Time Signal on
and off
Press D while in the Alarm Mode to change the status of the Daily Alarm and
Hourly Time Signal in the following sequence.

Whenever there is a sensor malfunction, be sure to take the watch to an
authorized CASIO distributor or Service Center as soon as possible. If the
appearance of the
BAT message is caused by extremely low
temperature, the message should clear from the display when normal
temperature returns. It is recommended, however, that you still have the
watch checked by an authorized CASIO distributor or Service Center.
Battery Replacement
ALWAYS LEAVE BATTERY REPLACEMENT UP TO THE DEALER
WHERE YOU BOUGHT THE WATCH OR TO AN AUTHORIZED CASIO
DISTRIBUTOR. BE SURE TO SHOW THE FOLLOWING INFORMATION
TO THE PERSON REPLACING THE BATTERY.
Attention dealer or CASIO distributor
Be sure to use the following procedure when replacing the battery.
1. Open and remove the back cover.
• If
CLOSE appears on the display when you open the back cover, replace
the back cover. Wait for a few minutes and try again.
• The message
WAIT on the display after you replace the cover indicates
that the watch is storing data to or recalling data from EEPROM. Wait for a
while before replacing the battery to give the
WAIT message a chance to
clear. If
WAIT remains on the display for a long time, go ahead and
replace the battery.
2. Remove the battery holder.
3. Remove the old battery and load a new one.
4. Replace the battery holder.
5. Touch the AC contact and the battery (+) side with metallic tweezers.
6. Close the back cover.
ERROR WARNING FUNCTIONS
This watch is designed to automatically stop taking measurements when there
is a sensor malfunction, when battery power drops below a certain level, or
when battery voltage is decreased below a certain level due to very cold
temperatures.
Important!
• If the sensor is malfunctioning when it comes time for an barometric
pressure measurement to be taken, the barometric pressure value appears
as
xxxx on the display and the corresponding point on the barometric
pressure graph is left blank.
•
marks flash next to ALM, SIG and A-LIGHT whenever there is a
momentary voltage drop due to continuous use of the backlight, etc. The
marks stop flashing when voltage returns to its normal level.
• The alarm, hourly time signal, and backlight are all disabled whenever the
marks are flashing on the display.
• All functions, except for mode change operations, are disabled while the
BAT message is on the display.
• There may be cases 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.

ABOUT ALTITUDE AND AIR
PRESSURE MEASUREMENTS
Altimeter
Generally, air pressure and temperature decrease as altitude increases. This
watch bases its altitude measurements on International Standard Atmosphere
(ISA) values stipulated by the International Civil Aviation Organization (ICAO),
which define relationships between altitude, air pressure, and temperature.

Sea
There are two standard methods of expressing altitude: Absolute altitude and
relative altitude. Absolute altitude expresses an absolute height above sea
level. Relative altitude expresses the difference between the height of two
different places.
