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 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.
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.

• 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.

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

General Guide
• The illustration below shows which buttons you need to press to navigate
between modes.
• In any mode, press L to illuminate the display.
• You can use buttons A, B, and C to enter a sensor mode directly from
the Timekeeping Mode or from another sensor mode. To enter a sensor
mode from the Data Recall, World Time, Stopwatch, Countdown Timer,
Alarm, or Receive Mode, first enter the Timekeeping Mode and then press
the applicable button.

• 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.
