Power Supply
The power supply of this watch uses a solar cell to generate
electrical power, which is stored by a rechargeable battery. Using
or storing the watch where it is not regularly exposed to light, or
allowing it to be blocked from light by your sleeve for long periods
as you are wearing it can cause the power of the rechargeable
battery to run down. To ensure stable operation, be sure to allow
the watch to be exposed to light as much as possible when you
are wearing or storing it.
Important!
Note that all data in memory and all settings are cleared whenever
you allow the level of the rechargeable battery to drop to Level 4.

Digital display, face illumination, tones (alarm,
hourly time signal), time calibration signal
reception, and analog timekeeping disabled.
All functions, including timekeeping,
disabled.
• Exposing the watch to direct sunlight or other strong light may
cause the battery level indicator to momentarily indicate a level
that is higher than the actual battery level. Because of this, you
should wait for a short while after charging to check the battery
level indicator.
• When the battery level approaches Level 3, the indicator below
L-CHG of the battery level indicator will start to flash, and the
analog hands will move to the 12 o’clock position.
• Even after the battery drops to Level 4, you will be able to resume
normal operation by charging the battery.
• When charging from Level 4, the display will start operating when
the battery reaches Level 3. At this time, you will be able to
configure digital time and date settings only. The analog hands will
start to operate when the battery reaches Level 2. At that time,
adjust the analog hand setting so it matches the digital time.
• When charging the battery, keep the watch exposed to light until
the battery reaches Level 2 or Level 1.

Face Illumination
An LED light is used to illuminate the face of the watch for easy
reading in the dark. An auto light switch automatically illuminates
the face when you angle the watch towards your eyes for reading.
❚
To illuminate the face manually
LL
Press the
L button in any
LL
mode (except while a setting
screen is on the display).
• This turns on LEDs located at 3
o’clock and 9 o’clock, which
illuminate the face of the watch.
• You can use the procedure under
“To specify the illumination
duration” to configure the
illumination duration as
approximately 1.5 seconds or 2.5
seconds.
• Pressing the L button illuminates the face regardless of whether
the auto light switch is on or off.
You may hear a faint rattling sound when you move the watch
around. This sound is caused by the movement of a metal
bulb that controls operation of the auto light switch, and does
not indicate malfunction.
❚
To illuminate the face with the auto light
switch
The auto light switch automatically illuminates the face
whenever you angle the watch towards your eyes for reading,
but only when it is dark.
• The auto light switch does not illuminate the face when
surrounding light is bright.
You can use the procedure under “To specify the illumination
duration” to configure the illumination duration as
approximately 1.5 seconds or 2.5 seconds.
❚
To turn the auto light switch on and off
While a setting screen (one on which a setting is flashing) is on the
display, hold down the L button for about two seconds to toggle
the auto light switch on (auto light switch on indicator displayed)
and off (no indicator displayed).

Power Saving
Power Saving automatically causes the watch to enter a sleep state and save power whenever the watch is left in the dark. The Power
Saving feature of the watch is turned on at the factory.
• Note that the watch may also enter the sleep state if the watch is blocked from light by your sleeve.
❚
How the sleep state works
Display sleep state
The display sleep state is triggered whenever the watch is left in
the dark for three or four days.
• The display sleep state causes the display to go blank, except for
a flashing Power Saving indicator. The alarm and the hourly time
signal continue to operate normally while the watch is in the
display sleep state. Even when the watch is in the sleep state,
digital-analog time coordination and time calibration signal auto
receive are both performed.
• The watch will not enter the display sleep state if it is in the
Stopwatch Mode.
Function sleep state
The function sleep state is triggered whenever the watch is left in
the dark for four days.
• The alarm and the hourly time signal are disabled while the watch
is in the function sleep state. In the function sleep state, the
analog hands stop and time calibration signal auto receive is not
performed.
• Digital timekeeping functions continue to operate normally in the
function sleep state.
❚
Positioning Your Arm Correctly

With the watch on
your wrist, position it
level with the ground.
• You should be wearing the watch on the outside of your wrist
when using the auto light switch.
• Make sure that the left (9 o’clock) and
right (3 o’clock) sides of the watch are
within ±15 degrees of being parallel
with the ground. The auto light switch
may not operate properly if the angle is
greater.
Important!
• The light may be difficult to see if you turn it on under bright
sunlight.
• If you press the B button or if an alarm operation starts while the
face is illuminated, illumination will turn off.
• Face illumination does not work while you are performing a time
calibration signal manual receive operation.

❚
To recover from the sleep state
Move the watch to a brightly lit location or press any button. The
watch will also recover from the sleep state if you angle it towards
your eyes for reading (see “To illuminate the face with the auto
light switch”).
• It can take up to two seconds before display figures re-appear
after you place the watch in a well-lit area.
❚
To turn Power Saving on and off
Use the procedure under “Configuring Home Time Settings” to turn
Power Saving on or off.
Leaving the watch in a drawer or anywhere else it is dark can
cause Power Saving to trigger in order to conserve battery
power.
Auto Light Precautions
• Frequent use of the auto light can run down the battery.
• The auto light switch may cause the face to illuminate when your
sleeve covers the face of the watch.
• The face may not illuminate immediately when you angle the
watch towards your face. This does not indicate malfunction.
• The face remains illuminated for the currently set duration (1.5 or
2.5 seconds) only, even if you leave the watch angled towards
your face.
• The auto light switch is automatically disabled whenever battery
power is at Level 3 or lower.
• The face may illuminate unintentionally when you wear the watch
on the inside of your wrist, when you shake your arm, or when
you raise your arm. Be sure to turn off the auto light switch
whenever you do not need face illumination.
• Keep the auto light switch turned off whenever you are wearing
the watch on the inside of your wrist.
• Electro-static charge and magnetism can interfere with auto light
operation and even make operation impossible. If this happens
lower your arm to the starting position and then raise it again. If
you still have trouble with illumination, try lowering your arm down
to your side and then raise it to your face for reading.

Reception Range
This watch is designed to receive the standard time calibration signal of Japan (JJY) or of the United States (WWVB). The signal that is
received depends on the current Home City setting.
• For information about selecting a Home City, see “Configuring Home Time Settings”. For information about city codes, see the “World Time
City Code List”.

• Under optimum conditions, the calibration signal should be
receivable up to 1,000 kilometers from the transmitter. Note
that the wave is relatively weak at distances greater than
500km, so reception may be poor at long distances.
• Geographic contours, nearby buildings, seasonal conditions, the time of day, can even make reception impossible even when you are within
range of the transmitter.
• Best reception is possible late at night.

How a Radio-controlled Watch Works
What is a radio-controlled watch?
Your radio-controlled watch is designed to receive a time
calibration signal that contains standard time data, and adjust its
current time setting accordingly.

After the watch receives the Standard Time signal, it performs
internal calculations to determine the current time. Because of
this, there may be an error of up to one second in the
displayed time.

Location
Reception is difficult and may even be impossible in the locations
described below. Avoid such locations when performing signal
reception.
• You should think of your watch operating like a radio or TV when it
is receiving the calibration signal.
Near high-voltage linesAmong or near buildings
Inside a vehicle
(automobile, train, plane, etc.)
In a location where there is
radio interference
(construction site, airport, etc.)
If you are experiencing problems with reception, move away
from the types of locations described above to a location with
better reception, and try again.
Next to a household appliance
or office equipment (TV, speaker,
fax, computer, cell phone, etc.)
Near mountains
Calibration Signal
• The Japanese calibration signal (Call Sign: JJY) is maintained by
the National Institute of Information and Communications
Technology (NICT). It is a long wave signal transmitted 24 hours a
day from the Mt. Otakadoya transmitter (40kHz) located in
Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane
transmitter (60kHz) located on the border between Saga
Prefecture and Fukuoka Prefecture.
• The U.S. calibration signal (Call Sign: WWVB) is transmitted by
the National Institute of Standards and technology from Fort
Collins, Colorado.
Note that transmission of the time calibration signal may be
interrupted occasionally due to maintenance, lightning, etc.
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration signal.
• Auto receive (Reception is performed automatically at
midnight, 1:00, 2:00, 3:00 and 4:00 each morning.)
•
Manual receive (You initiate reception using a button operation.)
• If reception is not successful for any of the normal auto receive
operations shown above, auto receive is performed one more
time at 5:00 a.m.
•
The watch is set up for auto receive at the factory, so all you need to
do is to place it in a location that allows good reception each night.
❚
To position the watch for optimum reception
Remove the watch from your wrist and place it somewhere so its
top (12 o’clock side, where the antenna is located) is facing
approximately in the direction of the signal transmitter. Keep the
watch away from metal objects.

Metal band
• Orienting the watch so it is sideways to the transmitter makes it
more difficult to receive the signal.
• Do not move the watch while it is receiving the calibration signal.
