4. Reception of Radio Waves
There are three ways to receive radio waves consisting of Automatic Regular
Reception, Free Reception and Recovery Automatic Reception. Always make sure to
remove the watch from your wrist to receive radio waves. When reception is completed,
each hand automatically moves forward or backward to the received time.
Regular Automatic Reception (Automatic reception of radio waves)
iPlace the watch in a stable location where radio waves can be received easily such as
by a window with the 9:00 position of the watch facing in the direction of the radio
wave transmitter station. Radio waves are automatically received at 2:00 AM every
day, or if they are unable to be received at that time, are automatically received at
4:00 every day.
Free Reception (Manual reception of radio waves)
iThis function allows you receive radio waves at any time.
Step 1): Continuously depress button (A) for about 2 seconds, and release when
the second hand has rapidly advanced to "RX" (12:00 position) and stopped.
Step 2): Place the watch in a stable location where radio waves can be received
easily such as by a window with the 9:00 position of the watch facing in
the direction of the radio wave transmitter station.
LThe second hand then moves from RX to H, M or L indicating that radio
waves are being received.
LWhen reception is completed, the second hand moves from H, M or L and
returns to 1-second interval movement.
The reception result can be confirmed by referring to "4. B. Confirmation of
Reception Result".
Recovery Automatic Reception
iAfter the watch has stopped as a result of being
insufficiently charged, radio waves are received once
automatically when the watch is sufficiently recharged by
exposing to light. Try to keep the watch charged at all
times so that it does not become insufficiently charged.
* When the watch is receiving the radio wave signal, all of
the hands will stop. To check the time, hold button (A) for 2
seconds to cancel radio wave reception. The hands will then return to the current time.

79
B. Confirmation of Reception Result
iThis function allows you to check whether radio wave reception has been successful or
failed.
Step 1): Press button (A) once. The second hand rapidly moves to H, M, L or NO
to indicate the reception result.
Step 2): The second hand automatically returns to normal hand movement after
the reception result has been displayed for 10 seconds. The second
hand can also be returned to 1-second interval movement by pressing
button (A) while the reception result is displayed.
LIf the second hand indicates NO for the reception result, try receiving radio waves by free
reception after finding a location and direction where radio waves are received easily.

8. Hand Correction Function
(Hand Reference Position Automatic Correction Function)
What is the Hand Correction Function ? (Hand Reference Position
Automatic Correction Function)
This function checks the hand positions at predetermined intervals to determine if
the hand reference positions are correct, and if they are detected to have shifted out
of position, rapidly corrects the second, minute and hour hands to automatically
keep the correct time.
Shock Detection Function
This function prevents the second, minute and hour hands from shifting when the
watch is subjected to shocks.
LIf the watch should happen to be subjected to a strong impact or placed in an
environment subjected to magnetism or static electricity, the correct time may not be
displayed even if radio waves are received. If this happens, check the reference
position. Refer to "9. Checking the Reference Position" on the following page.
9. Checking the Reference Position
Radio wave watches display the standard time and date received on the basis of a hand
reference position of "12:00:00", a date of the "1st", and "SUN" for the day.
iCheck that the reference position is
displayed correctly.
(1) Continuously depress button (B) for about
5 seconds or more with the crown at the
normal position, and release once the
second hand has begun to move either
forward or backward. All of the hands and
calendar move rapidly and stop at the
reference position stored in the memory of
the watch.
LThis may take up to about 7 minutes.

10. Manually Correcting the Reference Position
Correct the reference position if the watch does not indicate 12:00:00 for
the time, the 1st for the date and SUN for the day.
<Correcting the Reference Positions of the Hour Hand,
Minute Hand, Second Hand, Date and Day>
Step 1): Press button (B) for about 5 seconds or more, release it once the
second hand has started to move rapidly, and then wait after pulling the
crown out to Position 2 while the hand is moving.
Step 2): Turn the crown to align the date at
"1".
AContinuously turning the crown (by 2 clicks
or more) to the right causes the date to
change continuously, while continuously
turning to the left causes it to return.
LTurn the crown to the left or right to stop
the date from changing.
BWhen a "1" appears in the center of the date window on the watch dial, turn the
crown to the left or right to stop the date from changing.
LEach time button (A) is pressed once, the date, day or second hand to be
corrected moves indicating that the watch is in the correction mode.
Step 3): Press button (A) once and turn the crown to set the day to "SUN".
ATurning the crown continuously to the right (by 2 clicks or more) causes the day to
change, while turning continuously to the left causes it to return.
Step 4): Press button (A) once and turn the crown to set the hands to "00:00:00".
ATurning the crown to the right (by 1 click) causes the second hand to advance
rapidly by 1 minute, while turning it to the left causes the second hand to move
back by 1 minute.
BContinuously turning the crown (by 2 clicks or more) causes the second hand to
rotate rapidly, and the minute hand and hour hand moves continuously in
coordination with the second hand.
Step 5): After setting the reference position, return the crown to the normal
position and press button (B) once to rapidly return each hand, date and
day to the current time and date.
LAlthough this completes the procedure for setting the reference position, perform
free reception before using to set the watch to the correct time.

11. Photoelectric Power Generation Function
This watch uses a secondary battery to store electrical energy. Once fully charged, this
watch will continue to keep the correct time for about 6 months during normal use.
<For Optimum Use of this Watch>
In order to use this watch comfortably, try to store the watch
in a bright location at all times.
jWhen not wearing your watch, try to place it next to a
window or other bright location that allows the dial to
be exposed to sunlight. This will keep the watch
charged and enable it to continue to run properly at all
times.
jIf you usually wear long sleeves, the watch may
be covered thereby preventing it from being
exposed to light resulting in the watch becoming
insufficiently charged. It is recommended to
charge the watch once a month by exposing to
direct sunlight.
[NOTE] Avoid charging the watch at a location
such as an automobile dashboard or
other location that reaches a high
temperature.
Photoelectric Power Generation jCharge the watch by exposing the watch dial to direct sunlight
or light from a fluorescent lamp.

12. Unique Functions of Solar-Powered Watches
iWhen the watch becomes insufficiently charged, the display changes as shown
below.
*1 If the watch has stopped as a result of being insufficiently charged:
· A minimum of about 30 minutes are required until recovery automatic reception even if the watch
is exposed to light.
*2: If recovery automatic reception has failed:
· Since the time is incorrect even if the second hand is moving at one second intervals, first set the
time and date manually or by free reception before using the watch.

A. Power Save Function
When the watch dial is continuously not exposed to light for 90 days or more, each hand
stops at the 12:00 position and the watch enters the Power Save mode (to reduce power
consumption).
[The following functions continue to
operate in the power save mode.]
LRegular automatic reception is still performed.
When radio waves are unable to be received
by regular automatic reception at 2:00 AM
every day, radio waves are attempted to be
received automatically again at 4:00 AM.
LTime is continuously kept internally by the
watch.
LThe calendar (date, day) is changed
automatically.
<Canceling Power Save>
The power save function is canceled automatically when the watch dial is exposed to
light.
LWhen the power save function is canceled, each hand rapidly returns to the current
time and the second hand begins one-second interval movement.
LTwo-second interval movement begins if the watch is insufficiently charged. When
this happens, sufficiently charge the watch so that it returns to one-second interval
movement.
[Note]
· Although regular automatic reception is performed while the watch is in the Power
Save mode, radio waves may not be able to be received depending on the storage
environment. Check the reception result by pressing button (A) after the Power Save
function has been canceled. If the reception result is "NO", perform free reception
before using.
· Power save cannot be canceled by operating the crown or buttons. It can only be
canceled by exposing the watch to light.
