Power Saving
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.
❚ How the sleep state works
❚ To recover from the 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 watch enters the display sleep state, which 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.
• The watch does not enter the sleep state if it is in the
Stopwatch Mode.
Place the watch in an area that is well-lit, press any button, or
angle the watch toward your face to illuminate the display of the
watch using the Auto Light.
• It can take up to two seconds before display figures re-appear
after you place the watch in a well-lit area.

• The module number is engraved on the back cover of the
watch case.
• Function sleep state
The function sleep state is triggered whenever the watch is left
in the dark for six or seven days.
• The Power Saving 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.
• Digital timekeeping functions continue to operate normally
in the function sleep state.
❚ To turn Power Saving on and off
Use the procedure under “Configuring Time and Date Settings
Manually” to turn Power Saving on or off.
• Power Saving is designed to conserve power when you do
not use the watch for a long time.
• To conserve power, the World Time that you can display on
the Timekeeping Mode stops while the watch is in a sleep
state. When the watch recovers from a sleep state, the
Timekeeping Mode World Time restarts from the time that it
stopped when the sleep state was entered. To correct the
World Time, change to the World Time mode and then
return to the Timekeeping Mode. Note that the Timekeeping
Mode World Time will not stop if Power Saving is turned off.
• The actual appearance of your watch display depends on its module number.
• All display examples shown here use Module 2832. The module number is engraved on the back cover of the watch.

Operation Guide 2696/2832(B)
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 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.
❚ Flashing Recover Indicator
If you use the light or alarms a number of times during a short
period, a RECOVER indicator flashes on the display and the
following operations become disabled as battery power recovers.
• Display illumination,
• Alarm and hourly time signal
• Time calibration signal reception

• “2696” and “2832” indicate module numbers.
• 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 the Level
2 or Level 1.
When any screen besides a
setting screen (one with a
flashing setting), press the
B button to illuminate the
display of the watch.
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.
Depending on the light source you are using, the
case of the watch may become quite hot during
charging. Take care to guard against burn injury
after charging.
Illuminating the Display with the
Auto Light Switch
The full auto light switch automatically illuminates the display
whenever you angle the watch towards your face for reading,
but only when it is dark.
• The full auto light switch does not illuminate the display
when surrounding light is bright.
The auto light switch is very handy for reading the display in
the dark. The auto light switch illuminates the display for 1.5
seconds in all modes when you angle the watch towards your
face.
❚ To turn on the auto light switch
In any mode (except when a settings screen is on the display),
hold down the D button for about two seconds to toggle the auto
light switch on (auto light switch on indicator displayed) and off
(no indicator displayed).

❚ Charging Guide
Avoid charging the watch in the following locations, and anywhere
else where the watch may become very hot.
• On the dashboard of an automobile parked in the sun
• Very close to an incandescent light source or other sources of
heat
• In a location exposed to direct sunlight for long periods
Note that the display panel may become black under very high
temperatures. This is temporary, and the display will appear
normal again at lower temperatures.
❚ 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 Level 3 indicator starts to flash.
An EL (electro luminescent) panel is used to illuminate the display
of the watch for easy reading in the dark. An auto light switch
automatically illuminates the display when you angle the watch
towards your face for reading.
❚ Charging Precautions
With the watch on your
wrist, position it parallel
with the ground.
Auto Light Precautions

Rotate your arm so the watch
is angled at about 40 degrees,
so you can read its display.
At
least
40 o
• 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.
• Frequent use of the auto light can run down the battery.
• The auto light switch may turn on illumination when the display of
the watch is shaded by your sleeve.
• Illumination may not turn on immediately when you angle the
watch towards your face. This does not indicate malfunction.
• Illumination remains turned on for about 1.5 seconds only, even if
you leave the watch angled towards your face.
• The display 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 display 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 display illumination, try lowering your
arm down to your side and then raise it to your face for reading.
Display Illumination Precautions
• 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
display is illuminated, illumination will turn off.
• You may notice a slight sound from the watch while the display is
illuminated. This is the sound of EL panel vibration, and does not
indicate malfunction.

How a Radio-controlled Watch Works
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.

Internally
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 “Selecting Your Home City”. For information about city codes, see the “World Time City
Code List”.

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.
• 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.
• 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.
Location
Receiving the Calibration Signal
❚ Time Required for Reception
❚ Receive Icon
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.
There are two methods you can use to receive the time calibration signal.
• Auto receive (Reception is performed automatically at
midnight, 2:00, 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.
A calibration signal receive operation takes anywhere from about
two to six minutes.
• Note that when “FREQ.A” (Auto Select) is specified as the
transmitter selection mode, signal reception can take up to 12
minutes.
• See “Configuring Transmitter Selection Mode Settings” for more
information.
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.
Among or near buildings
Near high-voltage lines
❚ 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.
Inside a vehicle (automobile,
train, plane, etc.)
Next to a household appliance
or office equipment (TV,
speaker, fax, computer, cell
phone, etc.)
❚ To perform manual receive

seconds for reception to stabilize.
• Use the receive icon to check reception status and to
determine the best location for signal reception.
• Note that weather, the time of day, surroundings, and other
factors can all affect 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.
• The “ ” icon on the display also indicates successful signal reception.
The “ ” icon is cleared from the display each day at 3:00 a.m.

Calibration Signal Reception
Precautions
Troubleshooting
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• 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.
• 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.
• 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.
• 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?
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.
• 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
Home City code using the procedure under “Selecting Your Home
City”.
• Is auto receive turned off?
Use the procedure under “Configuring Auto Receive Settings” to
turn on auto receive.
• Is the watch in any mode other than the Timekeeping Mode or
World Time Mode during the auto receive times (midnight, 2:00
a.m., 4:00 a.m., and 5:00 a.m.)?
Auto receive is performed only when the watch is in the
Timekeeping Mode or World Time Mode. It is not performed if the
watch is in any other mode.
The watch cannot receive the time calibration signal.
Time calibration signal reception is successful, but the hourly
