Operation Guide 2839
Power Saving
Power Saving causes the watch to automatically enter a sleep state to save power whenever the watch is left in the dark. The Power
Saving feature 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.
❚
To recover from the sleep state
❚
How the sleep state works
Place the watch in an area that is well-lit, press any button, or
angle the watch toward your face to illuminate the display using
the Auto Light (see “To illuminate the display”).
•
Display sleep state
The display sleep state is triggered whenever the watch is left in
the dark for about one hour between the hours of 10 p.m. and 6
a.m.
•
It can take up to two seconds before display figures re-appear
after you place the watch in a well-lit area.
•
The display goes blank and a SLEEP indicator flashes on the
display. Alarms and the hourly time signal continue to operate
normally while the watch is in the display sleep state.
The watch does not enter the sleep state if it is in the
Stopwatch Mode.
❚
To turn Power Saving on and off
•
Use the procedure under “Configuring Time and Date Settings
Manually” to turn Power Saving on or off.
SLEEP Indicator
•
The watch automatically enters the sleep state if left in a
desk drawer or some other dark place for a long time while
Power Saving is turned on.
•
Function sleep state
The function sleep state is triggered whenever the watch is left
in the dark for six or seven days.
•
The SLEEP indicator stops flashing and remains on the display.
Alarms and the hourly time signal are also disabled while the
watch is in the function sleep state. Time calibration signal
reception is not performed while the watch is in the function
sleep state.
•
Timekeeping continues internally in the function sleep state.
Modes and Display Screens
•
•
The watch will automatically revert to the Timekeeping Mode if you leave it in the Alarm Mode or Recall Mode without performing any
operation for about two or three minutes.
In the Alarm Mode, an alarm number, the snooze alarm indicator (SNZ), or the hourly time signal indicator (SIG) identifies the currently
displayed screen.

Reception Range
How a Radio-controlled Watch Works
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 city codes, see the “Selecting Your Home City”.
What is a radio-controlled watch?
Calibration Signal
Your radio-controlled watch is designed to receive a time
calibration signal that contains standard time data, and adjust its
current time setting accordingly.
•
The Japanese calibration signal (Call Sign: JJY) is maintained by
the independent Japan Ministry of Posts and Telecommunications
Communication Research Laboratory (CRL). 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.

Geographic contours, nearby buildings, the season, 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.

Time Required for Reception
❚
Receive Icon
Location
Receiving the Calibration Signal
A calibration signal receive operation takes anywhere from about
two to six minutes.
The receive icon cycles from
“Unstable” through “Stable” as
shown below while reception is in
progress. How far it cycles depends
on the signal strength. Keep the
watch in a location where reception
is stable while reception is in
progress.
Reception is difficult and may even be impossible in the locations
described below. Avoid such locations when performing signal
reception.
There are two methods you can use to receive the time calibration
signal.
•
Note that when “AUTO” (Auto Select) is specified as the transmitter
selection mode, signal reception can take up to 12 minutes.
See “Signal Reception Settings” for more information.
•
Auto receive (Reception is performed automatically at 2:00,
3:00, 4:00, and 5:00 each morning.)
•
You should think of your watch operating like a radio or TV when it
is receiving the calibration signal.
•
•
Manual receive (You initiate reception using a button
operation.)
•
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.

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.
•
•
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.
•
The display will return to the normal timekeeping screen automatically
if you do not perform any operation for about one or two minutes.

button twice.
The watch cannot receive the time calibration signal.
Time calibration signal reception is successful, but the hourly
time signal and current time are slightly off.
•
•
•
Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
•
Is the signal being transmitted?
Though the Japanese calibration signal (Call Sign: JJY) is
continually transmitted by the independent Japan Ministry of
Posts and Telecommunications Communication Research
Laboratory (CRL) in theory, it may sometimes be interrupted for
periodic maintenance work, or because of lightening or other
problems.
•
After the watch receives the time calibration signal, it performs an
internal decoding process before updating its time setting.
Because of this, the time setting may be slightly off (within one
second).
•
•
This will exit the setting
screen and return to the
Timekeeping Mode screen.
Operating any button while auto reception is in progress will
cause the watch to beep and then exit the receive operation.
Make sure you are within the range of the calibration signal
transmitter before performing the reception operation. Remember
that geographic contours, nearby buildings, the season, the time
of day, can even make reception impossible even when you are
within range of the transmitter.
The display also will exit the setting screen automatically if
you do not perform any operation for about two or three
minutes.
Time calibration signal reception is successful, but the current
time is one hour fast.

•
Are you within the reception range of a transmitter?
See “Reception Range” for information about areas where the
watch can receive the signal.
Is there something in the immediate area that may be interfering
with reception?
•
Do you have summer time (DST) turned on?
•
•
Proper reception may be impossible if there is something blocking
the signal. If reception is unsuccessful, try again.
Use the procedure under “Configuring Summer Time (Daylight
Saving Time) Settings” to turn off summer time.
This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and
the United States only. Note that you will need to make your own
adjustments when using this watch outside of Japan or the United
States, or in any area that is outside the range of one of the
receivable time calibration signal transmitters.
Even if you are within the reception range of a transmitter, objects
between you and the transmitter or electrical noise can interfere
with reception. Avoid such areas during signal reception. See
“Location” for more information.
Time calibration signal reception is successful, but the current
time setting is wrong.

Do you have the correct Home City code selected?
Remember that auto receive is not performed unless TYO
(Japan), NYC (New York), CHI (Chicago), DEN (Denver), or LAX
(Los Angeles) is selected as the Home City. Select the correct

Stopwatch Mode
Configuring Time and Date Settings Manually
The stopwatch measures elapsed time in units of 1/100 second up to 23 hours 59 minutes, 59.99 seconds (24 hours). When the maximum
limit is reached, the elapsed time automatically returns to zero and timing continues from there.
Normally, you should never need to configure time and date settings manually if you have auto receive turned on and you are within the
range of a time calibration signal. If the watch is unable to update its settings automatically for some reason, however, you can configure
them manually as described below.
