Important!
Incorrectly calibrating the temperature measurement of this watch can result
in incorrect readings. Carefully read the following before doing anything.
•
Compare the readings produced by the watch with those of another
reliable, accurate thermometer.
•
If adjustment is required, remove the watch from your wrist and wait for
20 or 30 minutes to give the temperature of the watch time to stabilize.
To calibrate the temperature
1. Display the Barometric Pressure/
Temperature Display.
2. Hold down
A
until the display clears.
“OFF” or the temperature value should
be flashing on the display.
•
The “OFF” indicator appears when the
factory setting is being used for the
calibration.
3. Each press of
D
increases the displayed
temperature by 0.1
°
C while pressing
B
decreases it. Holding down either button
changes the value at high speed.
•
Any time you calibrate the temperature, the message “TEMP ADJ”
appears on the display. This message remains on the display in any
mode in which the temperature is displayed.
•
Pressing
B
and
D
at the same time returns to the “OFF” display.
4. After calibrating the temperature, press
A
to return to the Barometric
Pressure/Temperature Display.
•
If you do not operate any button for a few minutes while the temperature
digits are flashing, the flashing stops and the watch goes back to the
Barometric Pressure/Temperature Display.
Calibrating the barometric pressure measurement
The sensor of this watch is calibrated at the factory before shipment and
further adjustment is normally not required. If noticeable error is found in
the barometric pressure readings produced by the watch, you can adjust it
to correct the error.
Important!
Incorrectly calibrating the barometric pressure measurement of this watch
can result in incorrect readings. Compare the readings produced by the
watch with those of another reliable, accurate barometer.
To calibrate the barometric pressure
1. Display the barometric pressure and
temperature in the Timekeeping Mode.
2. Hold down
A
until the display clears.
“OFF” or the temperature value should
be flashing on the display.
3. Press
C
to show the barometric
pressure calibration display. At this time,
“OFF” or the barometric pressure value
should be flashing on the display.
•
The “OFF” indicator appears when the
factory setting is being used for the
calibration.
4. Each press of
D
increases the displayed barometric pressure by 1 hPa/
mb, while pressing
B
decreases it. Holding down either button changes
the value at high speed.
•
Pressing
B
and
D
at the same time returns to the “OFF” display.
5. After calibrating the barometric pressure, press
A
to return to the
Barometric Pressure/Temperature Display.
•
If you do not operate any button for a few minutes while the barometric
pressure digits are flashing, the flashing stops and the watch goes back
to the Barometric Pressure/Temperature Display.

THERMOMETER FUNCTIONS
A built-in temperature sensor measures temperature and shows the
measured value on the display. The thermometer can be calibrated.
Important!
Temperature measurements are affected by your body temperature (while
you are wearing the watch), direct sunlight, and moisture. To achieve a
more accurate temperature measurement, remove the watch from your
wrist, place it in a well ventilated location out of direct sunlight, and wipe off
all moisture from the case. It takes approximately 20 to 30 minutes for the
case of the watch to reach the actual surrounding temperature.
About temperature measurements
Temperature measurements are taken automatically every five minutes,
regardless of what mode the watch is in. Measured temperature values can
be viewed in the Timekeeping or Altimeter Modes. Temperature
measurements are taken every five seconds for the first three minutes after
you display the Timekeeping Mode’s barometric pressure/temperature
display, or after you enter the Altimeter Mode. After that, temperature
measurements are taken every five minutes.
•
Temperature measurement data can be recalled along with altitude
measurement data.
Understanding the temperature display
1. Use
C
to enter the Timekeeping Mode.
2. Press
D
to display the Barometric Pressure/Temperature Display.
•
The display shows “– –. –
°
C” if a measured value falls outside the range
of –10.0
°
C to 60.0
°
C. The normal display will return as soon as the
temperature returns within the allowable range.
•
For details on viewing the temperature in the Altimeter Mode, see
“Understanding the altimeter display”.

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 directional,
altitude, barometer, or temperature values on the display.
Abnormal Magnetic Field Indicator
This indicator appears whenever the Digital
Compass has a problem obtaining a correct
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 battery power
is too low to preform the measurement. It
appears whenever battery power drops
below a certain level, or when you try to
use this watch under very cold conditions
(below about –10.0
°
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 battery power is low (indicated “BAT” 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
pressure sensor circuitry. Whenever a
sensor malfunction initially occurs, the
“ERR” messages flashes on the display and
a buzzer sounds for three seconds.
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.
Important!
•
If the sensor is malfunctioning when it comes time for an barometric
pressure measurement to be taken, the barometric pressure value
appears as “– – – –” on the display and the corresponding point on the
barometric pressure graph is left blank.
•
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.
Whenever there is a sensor malfunction, be sure to take the watch to an
authorized CASIO distributor or Service Center as soon as possible.
