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-66).
• 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.)

Using the Crown
This watch has a lock-type crown.
Important!
• You should keep the crown locked during normal daily use. Leaving the crown unlocked creates the
risk of unintended operations or even damage due to impact.
To lock the crown
1. Push the crown back in (see "To pull out, rotate, or push the crown in"
below).
Mark 2 Mark 2
• Note that attempting to lock the crown when it is not pushed in can

cause unexpected watch operation.
2. Rotate the crown so Mark 1 is aligned with Mark 2.
3. While pushing in on the crown (a), rotate it to the right (b) until it stops,
and align Mark 1 with Mark 3.

High-speed Movement
You can use either of the crown operations described below to move watch hands or indicators at high
speed.
HS1: Can be used to move both hands and display indicators.
HS2: Can be used when setting the hour and minute manually to move the hands at high speed.
To start HS1 high-speed movement
While the crown is pulled out, rotate it rapidly three turns away from you (for
forward movement) or towards you (for reverse movement). High-speed
movement will continue even if you release the crown.
To start HS2 high-speed movement
While HS1 high-speed movement is in progress, again rotate the crown rapidly
three turns in the same direction as the current HS1 movement (away from you
for forward movement or towards you for reverse movement).
To stop high-speed movement
Rotate the crown in the direction that is opposite that of the current high-speed
movement or press any button.

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.

Important!
• Before performing any of these operations, fi rst unlock the crown.
The illustrations below show the different crown operations.
Pull out
Note
• If you do not perform any operation for more than two minutes after pulling out the crown, the indicator
shown below will appear and crown operations will become disabled. If this happens, push the crown
back in and then pull it out again to re-enable crown operations.
• Even if the indicator shown below appears immediately after you pull out the crown, crown operations
are disabled. If this happens, push the crown back in and lock it.
• You can use high-speed movement in the following cases: when changing the time and/or date setting
in the Timekeeping Mode, Countdown Timer Mode, or Alarm Mode, or when performing magnetic
declination angle calibration, altitude calibration, barometric pressure calibration, or temperature
calibration operations.
