Charging the Watch
The face of the watch is a solar panel 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, be sure
to leave it in a location
where it is exposed to light.
Best charging
x
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
makes sure that its face is
not blocked from light by the
sleeve of your clothing.
The watch may enter a
x
sleep state (page E-21) 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 x
Too close to an incandescent lamp x
Under direct sunlight x
Important!
x
Keep the watch 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 x
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.

When power drops to Level 4, all functions will be disabled but the watch will x
continue to keep time internally for about one week. If you recharge the battery
suffi ciently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
Charging Guide
The charging guide causes the x Second Hand to perform movement that gives you
a rough idea of whether the watch needs to be exposed to light in order to charge the
battery.
The current charging requirement is indicated whenever you push the crown x
back in from the fi rst click.
Failure to expose the watch to light when charging is required will cause the x
charge to be reduced even further.
The charging guide is based on a calculated value (not the actual battery
x
charge). Because of this, the battery charge may go low even if the charging
guide indicates that immediate charging is not required. If this happens, expose
the watch to light as soon as possible to charge the battery.

Power Saving
A Power Saving feature causes the watch to enter a sleep state automatically
whenever it is left for a certain period in an area where it is dark.
How Power Saving works
The watch will enter the sleep state if it is left in a dark location for about one week.
In the sleep state:
x
All hands stop at 12 o’clock. −
Auto Receive is disabled. −
Internal timekeeping continues to operate normally. −
The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch x
is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep
state.
E-21
Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See “Confi guring Time and
Date Settings Manually” (page E-35) for more information.
This section explains how the watch updates its time settings when the city name
selected as the current location is in Japan or China, and is one that supports time
calibration signal reception.
If your location setting is this:
CN (HKG, HONG KONG) Shangqiu City (China)
JP (TYO, TOKYO) Fukushima (Japan), Fukuoka/Saga (Japan)
OFF No signal received
Even when the watch is within range of a transmitter, signal reception may be x
impossible due to the effects of geographic contours, structures, weather, the time
of year, the time of day, radio interference, etc. The signal becomes weaker at
distances of approximately 500 kilometers, which means that the infl uence of the
above conditions becomes even greater.
Signal reception may not be possible at the distances noted below during certain
x
times of the year or day. Radio interference may also cause problems with
reception.
Fukushima or Fukuoka/Saga (Japan) transmitter: 500 kilometers (310 miles)
−
Shangqiu (China) transmitter: 500 kilometers (310 miles) −
As of December 2010, China does not use Daylight Saving Time (DST). If China x
does go to the Daylight Saving Time system in the future, some functions of this
watch may no longer operate correctly.
Using this watch in a country covered by a time calibration that is different from the
x
countries it supports may result in incorrect time indication due to local application
of summer time, etc.
The watch can receive the signal from the transmitter

x
With Auto Receive, the watch performs the receive operation each day
automatically. Reception times depend on the location settings: 2:00, 3:00, and
4:00 a.m. for JP (TYO, TOKYO), and 1:00, 2:00, and 3:00 a.m. for CN (HKG,
HONG KONG). When any receive operation is successful, none of the other receive
operations for that day are performed.
When a calibration time is reached, the watch will perform the receive operation.
x
The receive operation is not performed if a calibration time is reached while you are
confi guring settings.
