2. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To confi gure Home City settings” (page E-42) to
confi gure your Home City and daylight saving time settings.

Important!

Proper time calibration signal reception and World Time Mode data depend on
correct Home City, time, and date settings in the Timekeeping Mode. Make sure
you configure these settings correctly.

3. Set the current time.

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

E-12

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.
Expose the watch to bright light whenever possible.

Power Levels

You can get an idea of the watch’s power level by observing the battery power
indicator in the lower digital dial.

Battery power indicator

Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.

Best charging

x

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

x

sleep state (page E-19) if
its face is blocked by your
sleeve even only partially.

E-92 Specifi cations

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.

x

On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp x
Under direct sunlight x

Important!

x

Allowing the watch to become very hot can cause the digital displays to black out.
The appearance of the LCD should become normal again when the watch returns
to a lower temperature.

x

Turn on the watch’s Power Saving function (page E-19) 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.

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 x
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.

Power Recovery Mode

Performing multiple illumination, beeper, and/or high-speed hand movement x
operation during a short period may cause all of the battery power indicators (H,
M, and L) to start fl ashing in the lower digital dial. This indicates that the watch is in
the power recovery mode. Illumination, alarm, countdown timer alarm, and hourly
time signal operations will be disabled until battery power recovers.
Battery power will recover in about 15 minutes. At this time, the battery power

x

indicators (H, M, L) will stop fl ashing. This indicates that the functions listed above
are enabled again.
If all of the battery power indicators (

x H, M, L) are fl ashing and the CHG (charge)

message also is fl ashing, it means the battery level is very low. Expose the watch
to bright light as soon as possible.
Frequent fl ashing of all of the battery power indicators (

x H, M, L) probably means

that remaining battery power is low. Leave the watch in bright light to allow it to
charge.

For details about the operating time and daily operating conditions, see the “Power x
Supply” (page E-94) section of the Specifi cations.

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.

For information about enabling and disabling power saving, see “To turn Power

x

Saving on and off” (page E-83).

There actually are two sleep state levels: “display sleep” and “function sleep”.

Digital dials are off, but all functions

but timekeeping is maintained.

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.

x

The watch will not enter a sleep state while it is in the Stopwatch Mode or
Countdown Timer Mode.

To recover from the sleep state

Move the watch to a well-lit area or press any button.

Important!

x MOW, HNL and ANC are quite far from the calibration signal

The areas covered by
transmitters, so certain conditions may cause reception problems.
When

x HKG or BJS is selected as the Home City, only the time and date are

adjusted according to the time calibration signal. You need to switch manually
between standard time and daylight saving time (DST) if required. See “To
confi gure Home City settings” (page E-42) for information about how to do this.

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 Current Time and Date Settings Manually” (page E-48) for more
information.
This section explains how the watch updates its time settings when the city code
selected as the Home City is in Japan, North America, Europe, or China, and is one
that supports time calibration signal reception.

1,500 kilometers

The Anthorn signal is receivable
within this area.

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
conditions listed above 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.

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.

To get ready for a receive operation

Confi rm that the watch is in the Timekeeping Mode. If it isn’t, use 1. C to enter the
Timekeeping Mode (page E-38).

The antenna of this watch is located on its 12 o’clock side. Position the watch 2.
with 12 o’clock facing towards a window as shown in the nearby illustration.
Make sure there are no metal objects nearby.

What you should do next depends on whether you are using Auto Receive or 3.
Manual Receive.

Auto Receive: Leave the watch over night in the location you selected in step 2.

x

See “Auto Receive” below for details.
Manual Receive: Perform the operation under “To perform manual receive” on

x

page E-29.

Auto Receive

x

With Auto Receive, the watch performs the receive operation each day
automatically up to six times (up to fi ve times for the Chinese calibration signal)
between the hours of midnight and 5 a.m. (according to the Timekeeping Mode
time). 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

only if it is in the Timekeeping Mode or World Time Mode. The receive operation
is not performed if a calibration time is reached while you are confi guring settings,
while a countdown timer operation is in progress, or while the hands have been
moved for easier viewing of the digital dials (page E-79).

E-28

Signal reception normally is better x
at night.
The receive operation takes from three

x

to eight minutes, but in some cases
it can take as long as 16 minutes.
Take care that you do not perform any
button operation or move the watch
during this time.

Signal reception may be diffi cult or even impossible under the conditions x
described below.

Inside or
among
buildings

You can use the procedure under “To turn auto receive on and off” (page E-34) to x
enable or disable auto receive.
