• Note that the following conditions will prevent you from obtaining accurate
altitude readings:
When air pressure changes because of changes in the weather
Extreme temperature changes
When the watch itself is subjected to strong impact
There are two standard methods of expressing altitude: Absolute altitude and
relative altitude. Absolute altitude expresses an absolute height above sea
level. Relative altitude expresses the difference between the height of two
different places.
Height of building 130 m
(relative altitude)
Precautions Concerning Simultaneous Measurement of Altitude and
Temperature
Though you can perform altitude and temperature measurements at the same
time, you should remember that each of these measurements requires
different conditions for best results. With temperature measurement, it is best
to remove the watch from your wrist in order to eliminate the effects of body
heat. In the case of altitude measurement, on the other hand, it is better to
leave the watch on your wrist, because doing so keeps the watch at a
constant temperature, which contributes to more accurate altitude
measurements.
• To give altitude measurement priority, leave the watch on your wrist or in
any other location where the temperature of the watch is kept constant.
• To give temperature measurement priority, remove the watch from your
wrist and allow it to hang freely from your bag or in another location where
it is not exposed to direct sunlight. Note that removing the watch from your
wrist can affect pressure sensor readings momentarily.

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery
(secondary battery) that is charged by the electrical power produced by the
solar cell. The illustration shown below shows how you should position the
watch for charging.
Example: Orient the watch so its face is
pointing at a light source.
• The illustration shows how to position a
watch with a resin band.
• Note that charging efficiency drops when
any part of the solar cell is blocked by
clothing, etc.
• 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.
Important!
• Storing the watch for long periods in an area where there is no light or
wearing it in such a way that it is blocked from exposure to light can cause
rechargeable battery power to run down. Be sure that the watch is exposed
to bright light whenever possible.
• This watch uses a special rechargeable battery to store power produced by
the solar cell, so regular battery replacement is not required. However, after
very long use, the rechargeable battery may lose its ability to achieve a full
charge. If you experience problems getting the special rechargeable battery
to charge fully, contact your dealer or CASIO distributor about having it
replaced.
• Never try to remove or replace the watch's special battery yourself. Use of
the wrong type of battery can damage the watch.
• All data stored in memory is deleted, and the current time and all other
settings return to their initial factory defaults whenever battery power drops
to Level 5 and when you have the battery replaced.
• Turn on the watch's Power Saving function and keep it in an area normally
exposed to bright light when storing it for long periods. This helps to keep
the rechargeable battery from going dead.

rechargeable battery's power.

• The flashing
LOW
indicator at Level 3 tells you that battery power is very
low, and that exposure to bright light for charging is required as soon as
possible.
• At Level 5, all functions are disabled and settings return to their initial
factory defaults. Once the battery reaches Level 2 (indicated by M indicator)
after falling to Level 5, reconfigure the current time, date, and other
settings.
• Display indicators reappear as soon as the battery is charged from Level 5
to Level 2.
• Leaving the watch exposed to direct sunlight or some other very strong light
source can cause the battery power indicator to show a reading temporarily
that is higher than the actual battery level. The correct battery level should
be indicated after a few minutes.
• Performing multiple sensor, illumination, or
beeper operations during a short period may
cause all of the battery indicators (L, M, H) to
flash on the display. Illumination, alarm,
countdown timer alarm, hourly time signal, and
sensor operations will be disabled until battery
l
power recovers.
After some time, battery power will recover and
battery indicators (L, M, H) will disappear,
indicating that the above functions are enabled
again.
• Even if battery power is at Level 1 or Level 2, the Digital Compass Mode,
Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled
if there is not enough voltage available to power it sufficiently. This is
indicated by battery indicators (L, M, H) on the display.
• If battery indicators (L, M, H) appears frequently, it probably means that
remaining battery power is low. Leave the watch in bright light to allow it to
charge.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid
leaving the watch in the areas described below whenever charging its
rechargeable battery. Also note that allowing the watch to become very hot
can cause its liquid crystal display to black out. The appearance of the LCD
should become normal again when the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can
cause it to become quite hot. Take care when handling the watch to
avoid burn injury. The watch can become particularly hot when exposed
to the following conditions for long periods.
• On the dashboard of a car parked in direct sunlight
• Too close to an incandescent lamp
• Under direct sunlight
Charging Guide
After a full charge, timekeeping remains enabled for up to about five 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.
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)
• For details about the battery operating time and daily operating conditions,
see the "Power Supply" section of the Specifications.
• Stable operation is promoted by frequent exposure to light.
