Manual

MO1503-EA

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.

Warning !

• 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.

ENGLISH

Important!

• Your watch’s Altimeter Mode calculates relative altitude based on changes in barometric pressure

measurement by its pressure sensor. For more information, see pages E-51 and E-65.

• Immediately before embarking or otherwise taking altitude readings, be sure to specify a reference

altitude. If you don’t the readings produced by the watch probably will not be very accurate. For more

information, see “To specify a reference altitude value” (page E-56).

• To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before

using it. The watch may produce incorrect direction readings if you do not perform bidirectional

calibration. For more information, see “To perform bidirectional calibration” (page E-30).

2. 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-20) 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.

3. Set the current time.

See “Conﬁ guring Current Time and Date Settings” (page E-22).

The watch is now ready for use.

What is a quartz movement? Verified

Watches and clocks with a quartz movement are driven by a battery. This sends an electric current through quartz crystals that will vibrate. These vibrations are passed on to the movement. Because the vibrations have a fixed frequency, watches and clocks with a quartz movement are extremely precise.

There is moisture on the inside of the glass of my Casio watch, what should I do? Verified

Casio states that if the moisture appeared after an extreme change in temperature and disappears relatively quickly afterwards, there is probably nothing wrong. If the moisture does not disappear, you should have your watch repaired as soon as possible.
