To Improve Radio Signal Reception
• Place the watch in a place where it can easily receive a radio signal such as near a window.
The antenna is embedded at the 9 o’clock position of the watch. Turning the antenna toward
the outside of a window or the direction facing transmitting stations helps improve radio
signal reception.
• Do not move the watch while it is receiving radio signals.
To enhance the reception of radio signals, do not move
the watch or do not change the orientation of the watch
while it is receiving radio signals.
* If the button or crown is operated while the watch is
receiving a radio signal, the reception will be cancelled.

Q&A for the world time function
Q : Will the watch be automatically set to the local time when it is moved to a place in a
different time zone?
A : The watch will not be automatically set to the local time if it is just moved to a place
in a different time zone. Select the time zone where you are when you are abroad.
If you select the time zone, the watch is automatically set to the local time.
(The time difference can be adjusted in increments of 1 hour.)
After selecting the time zone, if it is within the reception range of radio signals, you
can leave the watch to receive the radio signal to set it to the precise time.
(The radio signal transmitting station can be changed by selecting a time zone.)
Q : The hands stop during operation of time zone setting, therefore, does time lag
occur?
A : The internal circuit stores the time, therefore, no time lag occurs.
Q : When a time zone for regions out of the radio signal reception range is set, the
watch will not receive a radio signal. How is the accuracy of the watch at that time?
A : The watch has an accuracy of a normal quartz watch in that case. ( Monthly rate:
±15 seconds)
Q :
How is adjustment made to a local time with a time difference of 15 minutes or 30
minutes?
A : The time can be adjusted on a 1 hour basis by use of the time difference adjustment
function.
When adjusting to a local time with a time difference of 15 minutes or 30 minutes.

TACHYMETER
(for models with tachymeter scale on the dial)
l
Tachymeter scal e can be us ed only when the time required is les s than 60 seconds.
To measure the hourly average speed of a vehicle
Use the stopwatch to
determine how many seconds
it takes to go 1 km or 1 mile.
Tachymeter scale indicated by
the STOP WATCH 1/5 -second
hand gives the average speed
per hour.
Ex. 1
STOPWATCH 1/5-
second hand:
40 seconds
Tachymeter scale:
"90"
“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or
miles and the STOPWATCH 1/5-second hand indicates “90” on tachymeter scale:
"90" (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph
"90" (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph

To measure the hourly rate of operation
Use the stopwatch to measure
the time required to complete 1
job.
1
Tachymeter scale indicated by
the STOP WATCH 1/5 -second
hand gives the average number
of jobs accomplished per hour.
2
Ex. 1
STOPWATCH 1/5second hand:
20 seconds
Tachymeter scale: " 18 0"
“180” (tachymeter scale figure) x 1 job
= 180 jobs/hour
Ex. 2: If 15 jobs are completed in 20 seconds:
"180" (tachymeter scale figure) x 15 jobs = 2700 jobs/hour

TELEMETER
(for models with telemeter scale on the dial)
l
The telemeter can provide a rough indication of the dis tance to the source of
light and sound.
l
The telemeter indicates the dis tance from your location to an object that emits
both light and sound. For example, it can indicate the distance to the place
where lightning s truck by measuring the time elapsed after you see a flash of
lightning until you hear the sound.
l
A flash of lightning reaches you almos t immediately while the sound travels to
you at a speed of 0.33 km/second. The distance to the source of the light and
sound can be calculated on the basis of this difference.
l
The telemeter scale is graduated so that the sound travels at a speed of 1 k m in
3 seconds.*
*Under the condition of temperature of 20° C(68° F)
The telemeter provides only a rough indication of the distance to the
place where lightning struck, and therefore, the indication cannot be used
as the guideline to avoid the danger of lightning. It should also be noted
that the speed of the sound differs depending on the temperature of the
atmosphere where it travels.
CAUTION
HOW TO USE THE TELEMETER
Before beginning, check that the stopwatch has been reset.
START
(Flash of light)
STOP
(Crash of thunder)
Press Button C to star t the
stopwatch as soon as you
see light.
When you hear the sound,
press Button C to stop the
stopwatch.
Read the telemeter scale
that the STOPWATCH 1/ 5second hand points to.
Approx. 3 k m
Please note that the STOPWATCH 1/5-sec ond hand moves in 1/5- second inc rements and does not
always point exactly to the graduations of the telemeter scale. The telemeter scale can be used only
when the measured time is less than 60 seconds.

ENERGY DEPLETION FOREWARNING FUNCTION
l
When the energy stored in the rechargeable battery is reduced to an extremely
low level, the second hand start s moving at 2-second intervals instead of the
normal 1- second inter vals. The watch remains accurate even while the second
hand is moving at 2-second intervals.
l When thi s occurs, re charge the wa tch as soon as p ossible by exp osing it to ligh t.
Other wise, the watch switches to fi ve-second inter val movement, f ollowed by a
completely stopped s tate.
•
Neither the buttons nor the crown can be operated while the second hand moves at twosecond or five-second intervals (this is not a malfunction).
•
While the second hand moves at five-second intervals, the hour and minute hands, and date
stop operating.
•
While the second hand moves at five-second intervals, the watch is unable to receive radio
signals automatically. After the watch is charged sufficiently and the second hand returns to
normal one-second interval movement, conduct the manual reception of radio signals to set
the watch to the correct time.
v TO PREVENT THE ENERGY DEPLETION
•
When wearing the watch, make sure that the watch is not covered by
clothing.
•
When t he w atch is not in us e, leav e it i n a brigh t pl ac e as long as
possible.

the stopwatch, the preliminary position may be misaligned.
The preliminary hand position may be misaligned due to the following reasons :
• In the case of a strong impact : Misalignment may occur when dropping or hitting the watch.
• In the case of a magnetic influence : Misalignment may occur when bringing the watch close to
an object which generates magnetism.
■
Automatic Hand Position Adjustment Function (Function to automatically

■
Setting the Preliminary Position of the Date/Stopwatch Hands
The hour, minute, and second hands have an "Automatic Hand Position Adjustment Function,"
which automatically corrects an incorrect preliminary position. It activates once a minute for the
second hand and at 12:00 both for the AM and PM for the hour and minute hands.
* This function works when the preliminary hand position is misaligned due to external factors
such as strong impact or magnetic influence. It does not work to adjust accuracy of the watch
or slight deviations which may occur during the manufacturing process.
* The preliminary position of the hour and minute hands can also be manually adjusted.
Since the preliminary position of the date and stopwatch hands is not automatically adjusted, it
must be adjusted manually.

Tro ub les Possible causes
Reception
of a radio
signal
When the watch is unable
to receive a radio signal
The reception results have
failed and the second hand
points to N (the watch does
not receive a radio signal).
The watch was moved while it was receiving a
radio signal.
The watch was left where the radio signal was weak
or where it was unable to receive a radio signal.
Transmitting stations may have stopped
transmitting radio signals for some reason
(Transmission stop).
The stopwatch 1/5 -second and minute hands
are not reset.
The watch is set to a time zone other than
receiving range.
Charging
the solar
battery
The stopped watch was
exposed to an adequate
light for longer than
“the time required to
fully charge the watch,”
however, it does not
resume its normal
one-second interval
movements.
The amount of exposed light is too weak.
The time for charging the watch is not
sufficient.
The built- in IC of the watch has fallen into an
unstable condition.
Solutions
Do not move the watch while it is receiving a radio signal.
Because it takes time to receive a radio signal successfully, leave the watch untouched
for 12 minutes at the longest.
Place the watch where it is able to easily receive a radio signal.
Check the website of each transmitting station for further information concerning a
transmission stop. Attempt to receive a radio signal again after a while.
Reset the stopwatch 1/5-second and minute hands.
①
Check the time zone that the watch is currently set for, and select the time zone.
②
When the watch is not displaying the precise time, receive a radio signal again if necessary.
The time required for charging the watch depends entirely on the amount of exposed
light the watch receives.
Refer to “GUIDELINE OF CHARGING TIME” to charge the watch.
Refer to “IMPROPER FUNCTION” to reset the built-in IC.
