Getting Acquainted

Congratulations upon your selection of this CASIO watch. To get the most out
of your purchase, be sure to read this manual carefully and keep it on hand
for later reference when necessary.

Expose the watch to bright light to charge its battery before using it.
You can use this watch even as its battery is being charged by exposure to
bright light.

Be sure to read “Power Supply” of this manual for important
information you need to know when exposing the watch to bright
light.

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.

If the digital display of the watch is blank...

If the PS indicator is on the display (either
flashing or steady), it means that the watch’s
Power Saving function has turned it off to
conserve power. Power Saving automatically
turns off the display and enters a sleep state
whenever the watch is left for a certain period
where it is dark.

The initial factory default setting is Power Saving on.

The watch will recover from the sleep state if you move it to a well-lit area,

*

if you press any button, or if you angle the watch towards your face for
reading.

*

It can take up to two seconds for the display to turn on.

See “Power Saving” for more information.

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 be
sure to use a second compass to confirm direction readings.

CASIO COMPUTER CO., LTD. assumes no responsibility for any loss,
or any claims by third parties that may arise through the use of this
watch.
