Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, leave it in a location where it
is exposed to light.
• Best charging performance is
achieved by exposing the watch to
the strongest light available.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
• The watch may enter a sleep state
(page E-14) if its face is blocked
by your sleeve even only partially.
Warning!
Leaving the watch in bright light for charging 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
E-10
Important!
• 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.
• Turn on the watch’s Power Saving function (page E-14) and keep it in an area normally exposed to
bright light when storing it for long periods. This helps to ensure that power does not run down.
• 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 power to run down. Expose the watch to bright light
whenever possible.

Power Levels
You can check the current battery power level by viewing the battery power indicator that appears on the
digital display when you enter the Timekeeping Mode.
• To enter the Timekeeping Mode from any other mode, hold down
D
for about two seconds.

• The fl ashing
L
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 (
M
) after falling to Level 5, reconfi gure the current time, date, and other settings.
• Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (
M
).
• 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.
• 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.
Charging Required Indication (by second hand)
When battery power reaches Level 3, the second hand of the watch will
jump at 2-second intervals in the Timekeeping Mode to let you know that
charging is required.
Power Recovery Mode
• Repeated sensor measurement, illumination, or use of tones over a short period of time may cause the
watch to enter a power recovery mode, which is indicated by a recovery indicator (
R
) to fl ash on the
digital display. The watch will remain in the power recovery mode until battery power recovers.
• Illumination, tones, and sensor operations are disabled and the hands of the watch stop until battery
power recovers.
E-13
• Battery power takes about 15 minutes to recover. The recovery indicator (
R
) will stop fl ashing and
normal watch operation will be restored when battery recovery is complete.
• Frequent fl ashing of the recovery indicator (
R
) indicates that battery power is low. Expose the watch to
light to charge its battery.

Power Saving
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”.
• With this watch, the Power Saving function cannot be disabled.
Elapsed Time in Dark Hands and Display Operation
60 to 70 minutes (display sleep)
Blank display, second hand
stopped at 12 o’clock.
Except for display and second hand, all
functions enabled.
6 or 7 days (function sleep)
Blank display, all hands
stopped at 12 o’clock.
Except for timekeeping, all functions
disabled.
• The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
• You will not be able to enter the Compass, Barometer/Thermometer, Altimeter, Stopwatch, or
Countdown Timer Mode while the watch is in a sleep state.
To recover from the sleep state
Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page
E-78).
