Charging Guide
After a full charge, timekeeping remains enabled for up to about seven months.
• The following table shows the amount of time the watch needs to be
exposed to light each day in order to generate enough power for normal
daily operations.
• Since these are the specs, we can include all the technical details.
• Watch not exposed to light
• Internal timekeeping
• Display on 18 hours per day, sleep state 6 hours per day
• 1 illumination operation (1.5 seconds) per day
• 10 seconds of alarm operation per day
• 10 hours of altimeter measurements, once per month
• Stable operation is promoted by frequent exposure to light.
Exposure Level (Brightness)
Outdoor Sunlight (50,000 lux)
Sunlight Through a Window (10,000 lux)
Daylight Through a Window on a Cloudy Day (5,000 lux)
Indoor Fluorescent Lighting (500 lux)

Reference
This section contains more detailed and technical information about watch
operation. It also contains important precautions and notes about the various
features and functions of this watch.
Auto Return Features
• The watch returns to the Timekeeping Mode automatically if you do not
perform any button operation for two or three minutes in the Data Recall,
Alarm, or Barometer/Thermometer Mode.
• If you do not perform any button operation while in the Altimeter Mode, the
watch returns to the Timekeeping Mode automatically after nine or 10 hours
(altitude measurement type : LONG) or after one hour (altitude
measurement type : SHORT).
• If you leave a screen with flashing digits on the display for two or three
minutes without performing any operation, the watch exits the setting
screen automatically.
Scrolling
The B and D buttons are used on the setting screen to scroll through data
on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Sensor Malfunction Indicator
Subjecting the watch to strong impact can cause sensor malfunction or
improper contact of internal circuitry. When this happens,
will appear
on the display and sensor operations will be disabled.
Barometric
Pressure
Measurement
Altitude
Measurement
• If appears while a measurement operation is being performed in a
sensor mode, restart the measurement. If
appears on the display
again, it can mean there is something wrong with the sensor.
• Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer
Mode or Altimeter Mode sensor may be disabled if there is not enough
voltage available to power it sufficiently. In this case,
will appear on
the display. This does not indicate malfunction, and sensor operation should
resume once battery voltage returns to its normal level.
• If
keeps appearing during measurement, it could mean there is a
problem with the applicable sensor.
Whenever you have a sensor malfunction, be sure to take the watch to
your original dealer or nearest authorized CASIO distributor as soon as
possible.
Button Operation Tone
The button operation tone sounds any time you
press one of the watch’s buttons. You can turn the
button operation tone on or off as desired.
• The following tones are not affected when you
turn off the button operation tone.
Alarm
Hourly Time Signal
Countdown Timer Mode alarm
Altitude alarm
Altitude storage confirmation tone
To turn the button operation tone on and off
In any mode (except when a setting screen is on the display), hold down C
to toggle the button operation tone on (
not displayed) and off (
displayed).
• Since the C button also is the mode change button, holding it down to turn
the button operation on or off also causes the watch’s current mode to
change.
• The
indicator is displayed in all modes when the button operation tone is
turned off.
Power Saving
When turned on, Power Saving enters a sleep
state automatically whenever the watch is left for
a certain period in an area where it is dark. The
table below shows how watch functions are
affected by Power Saving.
• There actually are two sleep state levels:
“display sleep” and “function sleep”.
• Wearing the watch inside the sleeve of clothing can cause it to enter the
sleep state.
• The watch will not enter the sleep state while the digital time is between
6:00 AM and 9:59 PM. If the watch is in the sleep state already when the
digital time reaches 6:00 AM, however, it will remain in the sleep state.
• The watch will not enter the sleep state while it is in the Altimeter,
Countdown Timer, or Stopwatch Mode.
