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.

Applications

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.

Keep the watch exposed to bright light

The electricity generated by the solar cell of the
watch is stored by a built-in battery. Leaving or
using the watch where it is not exposed to light
causes the battery to run down. Make sure the
watch is exposed to light as much as possible.

When you are not wearing the watch on your
wrist, position the face so it is pointed at a
source of bright light.

You should try to keep the watch outside of
your sleeve as much as possible. Charging is
reduced significantly if the face is covered only
partially.

Solar cell

The watch continues to operate, even when it is not exposed to light.
Leaving the watch in the dark can cause the battery to run down, which will
cause some watch functions to be disabled. If the battery goes dead, you
will have to re-configure watch settings after recharging. To ensure normal
watch operation, be sure to keep it exposed to light as much as possible.

Battery charges in the light.

Battery discharges in the dark.

The actual level at which some functions are disabled depends on the
watch model.

Frequent display illumination can run down the battery quickly and require
charging. The following guidelines give an idea of the charging time
required to recover from a single illumination operation.

Approximately five minutes exposure to bright sunlight coming in through
a window
Approximately 50 minutes exposure to indoor fluorescent lighting

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

If the display of the watch is blank...

If the display of the watch is blank, it means that the watch’s Power Saving
function has turned off the display to conserve power.

See “Power Saving” for more information.

The measurement functions built into this watch are not intended for
taking measurements that require professional or industrial precision.
