§5. RADIO SIGNAL RECEPTION
5-1 For Best Reception
There are three kinds of reception: automatic reception,
on demand reception, and recovery automatic reception.
When the radio signal has been properly received, your
watch will automatically adjust the time.
When reception is complete, each of the hands will move
either clockwise or counterclockwise to the received
time.
Remove the watch from your wrist and place on a stable
surface near a window where the radio signal can be
easily received, pointing the 9:00 position in the direction
of the radio signal transmitter.
Do not move the watch during reception.
• Reception may be difficult due to the surroundings or metal shielding.
• When inside a building, place the watch as close to a window as possible for good reception.
• Radio signal reception may be difficult during the hours around sunrise and sunset.
• Avoid attempting to receive radio signals during these times.
5-2 Poor Reception Areas
It may be difficult to properly receive the radio signals under certain environmental conditions
or in areas susceptible to radio noise.
• Inside reinforced concrete
buildings
Between tall buildings or
mountains, or underground
• Near cellular
phones that are
in use
• Inside vehicles, including
cars, trains and aero
planes
• Near TVs, refrigerators,
computers, fax machines and
other electrical equipment or
office appliances
• Extremely hot or cold locations • Near high-tension electrical
lines, railway overhead
wires or communication
facilities

§7. SOLAR POWER
7-1 Solar Power Function
This watch uses a secondary battery to store electrical energy.
When the watch is fully charged, it will maintain its accuracy for about 6 months.
<Ensuring best operation of the watch>
Always store the watch in a bright location for best results.
* Placing the watch near a window where its face can receive
sunlight or near another source of light when you are not wearing it
will ensure that the watch is regularly charged, allowing it to
maintain its accuracy.
* Wearing clothes with long sleeves makes it difficult for the watch to
get the necessary light, resulting in insufficient charging.
It is recommended that the watch be left in direct sunlight once a
month to charge it.
Note: Do not charge on surfaces that can easily become hot, such
as a car dashboard.

7-2 Characteristics of the Solar Powered Watch
When the watch is insufficiently charged, the indication will be changed as follows:
When a radio signal has
been successfully
received*2
[Normal indication]
The watch has been insufficiently
charged because the watch face,
which contains the solar cell, has not
received sufficient light.
[Insufficient charge warning]
2-second interval
movement
The second hand will begin a
2-second interval movement.
The insufficient charge
warning (a 2-second
interval movement)
continues for more
than 2 days.
The watch will stop
due to an insufficient
charging.
Sufficiently charge by exposing the watch
face, which contains the solar cell to
light.*1
[Recovery automatic reception]
When the watch is recharged
sufficiently, it will receive the radio
signal automatically once.
* 1. When the watch stopped due to insufficient charging
• It takes at least 30 minutes to recharge sufficiently to perform recovery
automatic reception, even if the watch is being exposed to light.
After recovery, refer to “Guide to Charging Time” (p. 14) and sufficiently
charge the watch.
* 2. If the watch failed to perform recovery automatic reception
• The time is incorrect even if the second hand moves at 1-second intervals, so
after fully charging the watch, set the time manually or perform on demand
reception.
A. Power Saving Function
If the watch face is not exposed to light for 7 days in succession, when the time reaches
12:00 midnight, the hands will stop and the watch will go into power saving mode.
* Even in power saving mode the watch will continue to keep time internally.
All hands stop at the 12:00:00 position.
12

16
<Canceling the power saving function>
The power saving function will be automatically canceled when the watch face is exposed
to light.
• When power saving function is canceled, the hands will return to their normal movement.
• If the watch is insufficiently charged, the second hand will begin the 2-second interval
movement. Charge the watch adequately to restore normal movement of the hands.
Notes:
• The power saving function cannot be canceled with crown or button operations.
Cancel the power saving mode by placing the watch in light.
• After the power saving mode has been canceled, press the lower right button Aonce to
check the reception status.
If it is not showing the correct time, carry out “On demand reception” (p.7) or “Setting the
Time Manually” (p. 10) before using.
B. Insufficient Charge Warning Function
The second hand’s movement changes from 1-second
intervals to 2-second intervals to show that the watch is
insufficiently charged.
The watch will stop due to an insufficient charging about
2 days after starting the 2-second interval movement.
Note: During 2-second interval movement, automatic
reception, on demand reception, time difference
setting and manual time setting are unavailable.
* If the charging insufficiency occurs during “Radio signal
reception”, “Confirming reception status”, “Time
difference correction” or “Checking/correcting the
reference position”, the operation will stop automatically, the watch will return to the time
before the operation, and 2-second interval movement will begin.
Regularly charge your watch so it does not become insufficiently charged.
C. Overcharging Prevention Function
Whenever the secondary battery becomes fully charged by exposing the solar cell to light,
the overcharging prevention function is automatically activated to prevent the battery from
being charged further.
No matter how much the watch is charged, it will not affect the secondary battery,
timekeeping, functions or performance of the watch.

Time for full charging:
The time for full charging after the watch has stopped due to an insufficient charging.
Note: A fully charged battery will run the watch for about 6 months without further
charging. The watch will maintain its accuracy for about 2 and a half years when
running in the power saving mode.
Charge the watch every day, as it will take a long time to recharge it, as is indicated
in the table, when it stops due to an insufficient charging.
Furthermore, it is recommended to charge your watch by exposing to direct
sunlight for a long time once a month.
E. Handling the Solar Powered Watch
CAUTION Charging precautions
• Overheating while charging can cause the watch exterior to become discolored, the watch
to deform or the movement to be damaged.
• Do not charge the watch in a high-temperature environment (about 60°C/140°F or more).
Examples:
• Charging close to incandescent lighting, halogen lamps, or other lighting sources that
easily become hot.
• Charging on surfaces that can easily become hot, such as a car dashboard.
• When charging with incandescent lighting, halogen lamps, or other lighting sources that
easily become hot, place the watch at least 50 cm (20 in.) away from the source to avoid
overheating.
WARNING Handling the secondary battery
• Do not remove the secondary battery from the watch yourself, unless unavoidable.
If you must remove the battery, store it out of reach of children to avoid accidental
ingestion.
• If the secondary battery is ingested, consult a doctor immediately.
WARNING Changing the secondary battery
• Although the secondary battery should never need to be changed, in rare instances, the
watch may be unable to be charged due to a problem with the battery.
If a problem occurs, have the watch repaired as soon as possible.

• Does the second hand align with the
RX (receiving) position?
• Press and hold the lower right button
Auntil the second hand has
reached the RX position.
The watch can receive the
radio signal, but it does
not show the correct time.
The second hand does not
align accurately with the
OK/RX/NO positions.
• Is the reference position set correctly? • Confirm the reference position. (p. 2)
If the reference position is not
correctly set, refer to “Correcting the
Reference Position” and correct the
reference position. (p. 11)
Reception is successful,
but the time is out by a
factor of hours.
• Check the time difference setting. • Set the correct time difference
setting. (p. 10)
Radio signal cannot be
received (where reception
is possible).
• Are there objects nearby that could
block radio signals or generate noise?
• Are you attempting to receive the radio
signal in a location far from a window?
• Avoiding objects that shield the radio
waves and sources of radio noise, try
to receive the signal with the 9:00
position of the watch pointing
towards a window.
Find a location such as window that
is conducive to radio signal
reception and change the watch
location, direction and angle. (p. 6)
• Was the watch moved during
reception while the second hand was
aligned with the RX position?
• Do not move the watch until the
signal has been properly received
(until normal hand movement
returns).
<Eco-Drive>
Problem Check Remedy
• The second hand is
moving at 2-second
intervals.
• The watch has stopped.
• The watch does not
work even after
charging.
• Did you charge the watch sufficiently
in sunlight?
• Charge the watch sufficiently, as
indicated in “Guide to Charging
Time”. (p. 14)
• If the watch does not work even after
charging, contact the Citizen Service
Center.
• The hands moved
forward quickly at the
moment that the watch
was removed from a
desk or drawer.
• This is because the power saving
mode was canceled when the watch
was exposed to light, and the hands
moved forward quickly to the current
time. It is ready to use. (p. 12)
