Operation Guide 2689
Power Saving
The Power Saving feature of the watch is turned on at the factory.
•
•
Power Saving causes the watch to automatically enter a sleep state to save power whenever the watch is left in the dark.
Note that the watch may also enter the sleep state if the watch is blocked from light by your sleeve.
•
Digital timekeeping functions continue to operate normally in
the function sleep state.
❚
How the sleep state works
•
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.
❚
To recover from the sleep state
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.
•
The display goes blank, except for a sleep indicator flashing on
it.
•
It can take up to two seconds before the display re-appears after
you place the watch in a well-lit area.
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 or off
Sleep indicator
Use the procedure under “Setting the Time and Date Manually” 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.
•
Function sleep state
The function sleep state is triggered whenever the watch is left in the
dark for six or seven days.
•
The sleep mark stops flashing and remains on the display.
Alarms, the hourly time signal, and auto signal reception are
also disabled while the watch is 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.
Entering the Alarm Mode displays an alarm number, “SNZ” (snooze alarm), or “SIG” (hourly time signal).

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 selecting a Home City, see “Setting the Time and Date Manually”.
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.
Transmitter
Home City
TYO
•
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.
Either the Mt. Otakadoya signal (40kHz) or the Mt.Hagane signal (60kHz)

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.
•
•
•
•
Under optimum conditions, the calibration signal should be
receivable up to 3,000 kilometers from the transmitter.
Note that the wave is relatively weak at distances greater
than 1,000km, so reception may be poor at long distances.
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.
•
•
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
Signal reception takes anywhere from about two to six minutes.
The receive indicator 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” is specified as the frequency selection
mode, signal reception can take up to 12 minutes.
•
Auto reception (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.
•
See “Specifying the Transmitter Mode” for more information about
the transmitter mode.
•
Manual receive (You initiate reception using a button operation.)
•
The watch is set up for auto reception at the factory, so all you
need to do is to place it in a location that allows good reception
each night.
❚
To trigger reception manually
In the Timekeeping Mode, hold
down the Dbutton for about
two seconds until the watch
beeps.
Receive icon
❚
To make reception easier
Among or near buildings
Near high-voltage lines
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 it
away from metal objects.
•
This indicates that manual receive
has started. The “ ” icon flashes
on the display while signal
reception is in progress.

❚
To stop signal reception

Press the D button.
(TV, speaker, fax, PC,
mobile phone, etc.)
Resin band
•
All other buttons besides D are disabled during signal reception.
•
•
Use the receive icon to check reception status and to
determine the best location for signal reception.
When reception is successful
The watch terminates reception and adjusts the current time. Next
it beeps and then displays the date and time the adjustment was
performed.
Note that weather, the time of day, surroundings, and other
factors can all affect reception.
•
The “ ” icon on the display also indicates successful signal reception.
The “ ” icon is cleared from the display each day at 3:00 a.m.
In a location where there is radio
interference
(construction site, airport, etc.)
Near mountains
When reception fails
The watch does not adjust its current time setting, and displays
Metal band
“ERR” instead.
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.

The following are the watch’s factory default settings, which are
configured automatically whenever you have the battery of the

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

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.
The “ ” icon is not on the display even though auto signal
reception is turned on.
Cause:
•
The “ ” icon appears after the watch
successfully receives the calibration
signal and adjusts the current time setting.
A single receive operation was not
successful.
The “ ” icon is displayed only when both
the hour-minute-second group and year-
month-day group were received. It will
not remain on the display if only the hour-
minute-second group is received.
The watch is not in the Timekeeping Mode
or World Time Mode when an auto
reception time is reached.
•
When the watch is unable to adjust its time signal using the
calibration signal for some reason, timekeeping accuracy is within
±15 seconds per month.
•
•
•
•
Strong electrostatic charge can cause timekeeping error.
Signal reception is cancelled if an alarm starts to sound while it is
being performed.
•
The watch’s calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.
