TACHYMETER
(for models with tachymeter scale on the dial)
To measure the hourly average speed of a vehicle

1 Use the stopwatch to determine how many seconds it takes to go 1 km or 1 mile.
2 Tachymeter scale indicated by the STOPWATCH 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

Tachymeter scale can be used only when the time required is less than 60 seconds.
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
30

To measure the hourly rate of operation
1 Use the stopwatch to measure Ex. 1 the time required to complete 1 job.
2 Tachymeter scale indicated by the STOPWATCH 1/ 5 -second hand gives the average number of jobs accomplished per hour.

STOPWATCH 1/5second hand: 20 seconds

Tachymeter scale: “180”
“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) The telemeter can provide a rough indication of the distance to the source of
light and sound. The telemeter indicates the distance from your location to an object that emits
both light and sound. For example, it can indicate the distance to the place where lightning struck by measuring the time elapsed after you see a flash of lightning until you hear the sound. A flash of lightning reaches you almost 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. The telemeter scale is graduated so that the sound travels at a speed of 1 km in 3 seconds.
Under the condition of temperature of 20° C(68° F)
CAUTION
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. 32

HOW TO USE THE TELEMETER Before beginning, check that the stopwatch has been reset.

START
(Flash of light)

2 When you hear the sound,

press Button C to stop the

stopwatch.

3 Read the telemeter scale that the STOPWATCH 1/5second hand points to.
Approx. 3 km
Please note that the STOPWATCH 1/5-second hand moves in 1/5-second increments 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.

HOW TO CHARGE AND START THE WATCH
u When you start the watch or when the energy in the rechargeable battery is reduced to an extremely low level, charge it sufficiently by exposing the watch to light. 1 Expose the watch to sunlight or strong artificial light. When the watch has stopped operating, the second hand will start moving at 2-second intervals. 2 Keep the watch exposed to the light until the second hand moves at 1-second intervals. 3 When the watch is charged after it has completely stopped, set the date and time before wearing the watch.
34

CAUTION
Caution for charging When charging the watch, do not place it too close to a photoflash
light, spotlight, incandescent light or other light sources as the watch temperature will become extremely high, causing damage to the parts inside the watch. When exposing the watch to sunlight to charge it, do not leave it on the dashboard of a car, etc., for a long time, as the watch temperature will become extremely high. While charging the watch, make sure the watch temperature does not exceed 60 °C.
OVERCHARGING PREVENTION FUNCTION
No matter how long the secondary battery is charged, the performance of the watch will not be degraded. When the secondary battery becomes fully charged, the overcharging prevention function will be automatically activated to prevent it from being charged further.

v The above table provides only a general guideline.

· The time required for charging the watch varies depending on the calibres. Check the calibre of your watch engraved on the back cover.
· It is recommended that the watch be charged for as long as the charging time “B” to assure the stable movement of the watch.

ENERGY DEPLETION FOREWARNING FUNCTION
When the energy stored in the rechargeable battery is reduced to an extremely low level, the second hand starts moving at 2-second intervals instead of the normal 1-second intervals. The watch remains accurate even while the second hand is moving at 2-second intervals.
When this occurs, recharge the watch as soon as possible by exposing it to light. Otherwise, the watch switches to five-second interval movement, followed by a completely stopped state.
· 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 the watch is not in use, leave it in a bright place as long as possible. 37

POWER SAVE FUNCTION
This watch is equipped with a power save function (Power Saving) which can suppress energy consumption when it is left without receiving an adequate light source for a certain length of time. * There are two types of power save mode.

Condition

Power Save 1
When the watch is exposed to a state without receiving an adequate light source
for 72 hours or longer.

Power Save 2
When the watch is in an insufficient charging state for a long time.

Situation

The second hand stops pointing at the 15-second position, and the hour and minute hands also stop.
The watch conducts automatic radio signal receiving.

The second hand stops pointing at the 45-second position, and the hour and minute hands also stop.
The watch does not conduct automatic radio signal receiving.

How to handle the situation

When the watch is exposed to an adequate light source for five seconds or longer, it displays
the current time again after the second hand is rapidly advanced.

After sufficiently charging the battery, set the watch for the current time, if necessary.

• If the “Power Save 2” mode is prolonged, the stored power amount drops and the internal current time information stored will be lost. When the watch returns to its normal movement of one-second interval after sufficiently charging the battery, set the current time by
  38 receiving a radio signal.

NOTE ON POWER SUPPLY
The battery used in this watch is a rechargeable battery, which is different from ordinary silver oxide batteries. Unlike other disposable batteries such as dry-cell batteries or button cells, this rechargeable battery can be used over and over again by repeating the cycles of discharging and recharging.
The capacity or recharging efficiency of the rechargeable battery may gradually deteriorate for various reasons such as long-term use or usage conditions. Worn or contaminated mechanical parts or degraded oils may also shorten recharging cycles. If the efficiency of the rechargeable battery decreases, it will be necessary to have the watch repaired.
When the secondary battery is fully charged, the overcharge prevention function is automatically activated to avoid further charging.
CAUTION
Do not remove the rechargeable battery yourself. Replacement of the rechargeable battery requires professional knowledge and skill. Please ask a watch retailer for replacement of the rechargeable battery.
Installation of an ordinary silver oxide battery can generate heat that can cause bursting and ignition.

PRELIMINARY POSITION
When the watch is unable to display the precise time or date even if it successfully receives a radio signal, or when the stopwatch hands do not stop at the 0-position even after resetting 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 adjust the preliminary position of the hand)
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.
Setting the Preliminary Position of the Date/Stopwatch Hands
Since the preliminary position of the date and stopwatch hands is not automatically adjusted, it must be adjusted manually.

Reception of a radio signal
Charging the solar battery
58

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 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 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.
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.
Check the time zone that the watch is currently set for, and select the time zone. When the watch is not displaying the precise time, receive a radio signal again if necessary.
