Power Saving
Power Saving causes the watch to automatically 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 about one hour between the times of 10:00 p.m. and 6:00 a.m.
• The display sleep state causes the display to go blank, except for a
flashing Power Saving indicator. 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, digitalanalog time coordination and auto signal receive are both performed.
• The watch will not enter the 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 disabled while the watch is
in the function sleep state. Analog timekeeping and calibration
signal auto time calibration signal receive is not performed in the
function sleep state.
• Digital timekeeping functions continue to operate normally in the
function sleep state.

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.
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.

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 standard wave may be
interrupted occasionally due to maintenance, lightening, etc.
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.

Operation Guide 3346
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.
Resin band
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.
❚
Time Required for Reception
A calibration signal receive operation takes anywhere from about
two to six minutes.
• Note that when “AUTO” (Auto Select) is specified as the transmitter
selection mode, signal reception can take up to 12 minutes.
• See “Configuring Auto Receive Settings” for more information.

Operation Guide 3346
Calibration Signal Reception
Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• Signal reception is not performed while a timer operation is being
performed.
• When a time calibration signal is received, the watch corrects its
digital time setting first, and then adjusts the analog time setting
accordingly. In order to ensure that the analog time matches the
digital time, make sure you adjust the analog time to match the
digital time before signal reception is performed.
• Pressing 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, seasonal conditions,
the time of day, can even 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. It operates like a standard (non-radio
controlled) watch outside of the range 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.
World Time Mode
World time lets you display the current time in any one of 30 cities
(29 time zones) around the world.
• When you enter the World Time Mode, the screen for the city that
was displayed when you last exited the mode appears first.
• The seconds count in the World Time Mode is linked with the
Timekeeping Mode seconds count.
• The same 12-hour/24-hour format you select for the Timekeeping
Mode time is also applied in the World Time Mode.
Important!
If the World Time Mode time is incorrect, correct the setting of the
current time in the Timekeeping Mode.
• For information about selecting a Home City, see “Configuring
Home Time Settings”.
