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 of the watch is turned on at the factory.
•Note that the watch may also enter the sleep state if its face is blocked from light by your sleeve.
❚ How the sleep state works
There are actually two sleep state levels, a “display sleep state”
and a “function sleep state”.
•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. The display sleep state causes the display to go blank.
•Alarms 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 display sleep state, analog time
timekeeping and auto signal receive are both performed.
•The watch does not enter the display sleep state if it is in the
Timer Mode or Stopwatch Mode.
•Function sleep state
The function sleep state is triggered whenever the watch is left in
the dark for six or seven days.
•Alarms and the Hourly Time Signal are also disabled while the
watch is in the function sleep state.
Analog time timekeeping and auto signal receive are not
performed while the watch is in the function sleep state.
•Timekeeping functions continue to operate normally in the
function sleep state.
❚ To recover from the sleep mode
Place the watch in an area that is well-lit, press any button, or
angle the watch towards your face to illuminate the display using
the auto light.
•It can take up to two seconds before the display re-appears after
you place the watch in a well-lit area.
❚ To turn power saving on and off
See the procedure under “Manually Setting the Time and Date”.
Leaving the watch in a drawer or anywhere else it is dark can
cause the power saving mode to trigger in order to conserve
battery power.

•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.
•Even if the battery level drops all the way to Level 4, you will still
be able to recharge the battery and use the watch again.
•When recharging from Level 4, set the current time and date after
the battery level recharges to Level 3. At this time you should
continue to expose the watch to light so it can charge up to Level
2 or Level 1.
❚ Start charging at Level 3!
Battery Level 3 indicates that remaining battery power is very low.
Be sure to expose the watch to light for recharging as soon as
possible after the battery level indicator shows Level 3.
Illuminating the Display with the
Auto Light Switch
The auto light switch automatically illuminates the display
whenever you angle the watch towards your face for reading,
but only when it is dark.
You can use the procedure under “Specifying the Illumination

the transmitter.
•Best reception is possible late at night.
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.
Signal is received using
built-in antenna.

Time is adjusted
according to time
data.
After the watch receives the time calibration 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.
Calibration Signal
•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.
Though the calibration signal is normally transmitted 24 hours
a day, transmission may be interrupted occasionally due to
maintenance, lightening, etc.

Troubleshooting
Cannot perform manual reception.
Cause: •Manual receive can be performed in the
Timekeeping Mode only.
•Manual receive cannot be performed
while a timer operation is in progress.
•The Home City is set to a city other than
TYO (Tokyo), NYC (New York), CHI
(Chicago), DEN (Denver), or LAX (Los
Angeles).
Corrective Measures: •Perform manual receive in the
Timekeeping Mode.
•Change the Home City to TYO (Tokyo),
NYC (New York), CHI (Chicago), DEN
(Denver), or LAX (Los Angeles).
Correctly set the Home City as detailed
under “Manually Setting the Time and
Date”.
The receive ( ) icon is not on the display even though auto
signal reception is turned on.
Cause: •The receive ( ) icon appears after the
watch successfully receives the
calibration signal and adjusts the current
time setting.
•A single receive operation was not
successful.
•The watch is not in the Timekeeping
Mode or World Time Mode when an auto
reception time is reached.
• You performed manual reception, which
clears the receive ( ) icon from the display.
Corrective Measures: •Check to make sure the watch is in a
location where it can receive the signal.
•Place the watch in a location where
reception conditions are good.
•Make sure that the watch is in the
Timekeeping Mode or World Time Mode
during the auto reception times.
Calibration Signal Reception
Precautions
•Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
•Signal reception cannot be performed while a timer operation is in
progress.
•Receipt of a calibration signal causes the digital time to be
adjusted first, followed by adjustment of the analog time. In order
to ensure correct adjustment of the analog time, be sure to match
the analog time with the digital time before performing a signal
receive operation.
•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 make reception impossible even when you are within
range of the transmitter.
•Proper reception may be impossible if there is something blocking
the signal. If reception is unsuccessful, try again.
•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.
•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.
DST Indicator
•If you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup
of the watch.
•The following are the watch’s factory default settings, which are
configured automatically whenever you have the battery of the
watch replaced.

Time setting is incorrect following signal reception.
Cause: •If the current time is advanced by one
hour, it probably means that summer time
is turned on (indicated by the DST
indicator).
•If there is a large error in the setting, it
probably means that the wrong Home
City is selected.
Corrective Measures: •Correctly configure the summer time and
Home City settings as detailed under
“Turning Summer Time On and Off” and
“Manually Setting the Time and Date”.
Cannot configure signal reception settings.
Cause: •The Home City is set to a city other than
TYO (Tokyo), NYC (New York), CHI
