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-24) to conﬁ gure your
Home City and daylight saving time settings.
Proper World Time Mode data depends 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-26).
The watch is now ready for use.

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.
Pulling out the crown while the watch is in a mode that does not allow conﬁ guration of any settings will
cause the indicator shown below to appear. If this happens, push the crown back in and lock it.
The indicator shown below also appears when performing hand home position adjustment. See “Hand
Home Position Adjustment” (page E-29) for more information.
You can use high-speed movement in the following cases: when changing the time and/or date setting
in the Timekeeping Mode, World Time Mode, Countdown Timer Mode, or Alarm Mode, or when
performing magnetic declination angle calibration, altitude calibration, barometric pressure calibration,
or temperature calibration operations.
You can use either of the crown operations described below to move watch hands or indicators at high
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 away from you (forward) or
towards you (reverse) until the desired HS1 high-speed movement starts.
To start HS2 high-speed movement
While HS1 high-speed movement is in progress, again rotate the crown rapidly,
away from you (forward) or towards you (reverse) in the same direction as the
HS1 movement until HS2 high-speed movement starts.
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.
Using the Crown
The crown of this watch is a screw in lock crown. Before using the crown,
you must ﬁ
rst rotate it towards you to loosen it. After performing crown
operations, be sure to press the crown in lightly as you screw it back in.
To maintain water resistance and avoid impact damage to the crown,
be sure to screw it back in when you are not using it.
The illustrations below show the different crown operations.

About This Manual
Depending on the model of your watch, digital display text appears
either as dark ﬁ
gures on a light background, or light ﬁ gures on a dark
background. All examples in this manual are shown using dark ﬁ
on a light background.
Button operations are indicated using the letters shown in the
Note that the product illustrations in this manual are intended for
reference only, and so the actual product may appear somewhat
different than depicted by an illustration.
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 watch’s altimeter while mountain climbing, be sure to perform regular calibration in
accordance with the local altitude (elevation) indications. For more information, see “To specify a
reference altitude value” (page E-46).
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.)
Congratulations upon your selection of this CASIO watch.
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 your watch or its malfunction.
