Congratulations upon your selection of this CASIO watch.  
Things to check before using the watch  
Applications  
1. Check the Home City and the daylight saving time (DST) setting.  
The built-in sensors of this watch measure barometric pressure, temperature and  
altitude. Measured values are then shown on the display. Such features make this  
watch useful when hiking, mountain climbing, or when engaging in other such outdoor  
activities.  
Use the procedure under “To configure Home City settings” to configure your Home  
City and daylight saving time settings.  
Important!  
Proper World Time Mode data depend on correct Home City, time, and date settings  
in the Timekeeping Mode. Make sure you configure these settings correctly.  
Warning !  
2. Set the current time.  
The measurement functions built into this watch are not intended for taking  
measurements that require professional or industrial precision. Values produced  
by this watch should be considered as reasonable representations only.

Altimeter Precautions  
When mountain climbing, you can specify a reference altitude value in accordance  
with a marker along the way or altitude information from a map. After that, the  
altitude readings produced by the watch will be more accurate than they would  
without a reference altitude value.  
This watch estimates altitude based on air pressure. This means that altitude  
readings for the same location may vary if air pressure changes.  
The semiconductor pressure sensor used by the watch for altitude measurements  
is also affected by temperature. When taking altitude measurements, do not subject  
the watch to temperature changes.  
Do not rely upon this watch for altitude measurements or perform button operations  
while sky diving, hang gliding, or paragliding, while riding a gyrocopter, glider, or  
any other aircraft, or while engaging in any other activity where there is the chance  
of sudden altitude changes.  
Do not use this watch for measuring altitude in applications that demand  
professional or industrial level precision.  
Remember that the air inside of a commercial aircraft is pressurized. Because of  
this, the readings produced by this watch will not match the altitude readings  
announced or indicated the flight crew.  
To take an altimeter reading  
1. Make sure the watch is in the Timekeeping Mode.  
Current time  
2. Press  
D
to start Altimeter measurement.  
ALTI will appear on the display, indicating that  
Altimeter measurement is in progress. The first  
reading will appear on the display after about four  
or five seconds.  
The current altitude value is displayed in units of 5  
meters (20 feet).  
After the first reading is obtained, the watch  
continues to take altimeter readings automatically  
every five seconds for the first three minutes, and  
then every two minutes after that.

Specifying Temperature, Barometric Pressure, and Altitude Units  
Use the procedure below to specify the temperature, barometric pressure, and altitude  
units to be used in the Barometer/Thermometer Mode and the Altimeter Mode.  
If you leave the watch in the Altimeter Mode, it will update the displayed altitude  
value regularly.  
Temperature is measured in the Barometer/Thermometer Mode and in the  
Altimeter Mode. For details about temperature readings, see "Temperature".  
Important!  
When TYO (Tokyo) is selected as the Home City, the  
altitude unit is set automatically to meters (m), the  
barometric pressure unit to hectopascals (hPa), and the  
temperature unit to Celsius (°C). These settings cannot  
be changed.  
3. After you are finished using the Altimeter, press  
Mode and stop auto measurement.

Normally, displayed altitude values are based on the watch’s preset conversion  
values. You also can specify a reference altitude value, if you want. See “Specifying  
a Reference Altitude Value” below.  
2. Keep pressing C until TEMP (temperature), ALTI (altitude), or BARO (barometric  
pressure) appears in the upper left corner of the screen.  
See step 3 under “To change the current time and date settings” for information  
about how to scroll through setting screens.  
You can change the unit for displayed altitude values to either meters (m) or feet (ft).  
See “To specify temperature, barometric pressure, and altitude units”.  
3. Perform the operations below to specify the units you want.  
Specifying a Reference Altitude Value  
To specify this unit: Press this key: To toggle between these settings:  
The altitude readings produced by this watch are subject to error caused by changes  
in air pressure. Because of this, we recommend that you update the reference altitude  
value whenever accurate altitude information is available during your climb. After you  
specify a reference altitude value, the watch adjusts its air-pressure-to-altitude  
conversion calculation accordingly.

Though you can perform altitude and temperature measurements at the same time,  
you should remember that each of these measurements requires different conditions  
for best results. With temperature measurement, it is best to remove the watch from  
your wrist in order to eliminate the effects of body heat. In the case of altitude  
measurement, on the other hand, it is better to leave the watch on your wrist, because  
doing so keeps the watch at a constant temperature, which contributes to more  
accurate altitude measurements.  
To give altitude measurement priority, leave the watch on your wrist or in any other  
location where the temperature of the watch is kept constant.  
To give temperature measurement priority, remove the watch from your wrist and  
allow it to hang freely from your bag or in another location where it is not exposed  
to direct sunlight. Note that removing the watch from your wrist can affect pressure  
sensor readings momentarily.

2. Press D (+) or B (–) to change the current reference  
altitude value by 5 meters (or 20 feet).  
Specify a reference altitude value based on  
accurate altitude information about your current  
location from a map, etc.  
You can set the reference altitude value within the range of –10,000 to 10,000  
meters (–32,800 to 32,800 feet).  
Pressing B and D at the same time returns to OFF (no reference altitude value),  
so the watch performs air pressure to altitude conversions based on preset data  
only.  
3. Press A to exit the setting screen.  
Checking the Current Time in a Different Time Zone

You can use the World Time Mode to view the current  
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). These values define  
relationships between altitude, air pressure, and temperature.

Barometer/Thermometer Mode and Altimeter Mode sensor operations are disabled  
whenever there is not enough battery power available to perform a sensor operation.  
This is true regardless of the current battery level. 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.
