Important!
The watch's Altimeter Mode calculates and displays relative altitude based on barometric pressure
readings produced by its pressure sensor. This means that readings taken at different times at the
same location may produce different altitude values due to changes in barometric pressure. Also note
that the value displayed by the watch may be different from the actual elevation and/or sea level
elevation indicated for the area where you are located.
When using the altimeter of this watch for mountain climbing or other activities, it is highly
recommended that you check a map, local altitude indications, or some other source for your current
correct altitude and regularly calibrate the altimeter with the latest information. For more information,
see "To specify a reference altitude value" (page E-47).
Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other
activities, be sure always to take along another compass to confi rm readings. If the readings produced
by the digital compass of this watch are different from those of the other compass, perform bidirectional
calibration of the digital compass to ensure more accurate readings.
Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a
permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or
electrical household appliances (TV, computer, cellphone, etc.)

Things to check before using the watch
1. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under "To confi gure Home City and summer time settings" (page E-14) to confi gure
your Home City and daylight saving time settings.
Important!
World Time Mode and Sunrise/Sunset Mode data depend on correct Home City, time, and date settings
in the Timekeeping Mode. Make sure you confi gure these settings correctly.
2. Set the current time.
See "Confi guring Current Time and Date Settings" (page E-16).
The watch is now ready for use.

Operation Guide 3439
Congratulations upon your selection of this CASIO watch.
Applications
The built-in sensors of this watch measure direction, 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.
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.
When engaging in mountain climbing or other activities in which losing your way can create a
dangerous or life-threatening situation, always use a second compass to confi rm direction readings.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss
suffered by you or any third party arising through the use of this product or its malfunction.
