the timer to return to the timer set time and starts
counting down again.
USING CHRONOGRAPH (STOPWATCH)
A. Chronograph Mode Display
This drawing shows the reset state in the
chronograph mode.
B. Using the Chronograph
For the chronograph, either split time measurement
or lap time measurement can be used optionally. A
maximum of 10 split or 10 lap times can be
memorised. The time when each split or lap time
measurement was finished can be recalled after all
of the required measurements have been taken.
The same procedure is used for both split and lap
measurements.
1. Select either the split time measurement or the
lap time measurement by pressing the 嘷
M button.
2. Press the 嘷
A button to start and stop the
chronograph. (Stop and start can be repeated
any required number of times simply by pressing
the 嘷
A button during the chronograph mode.)
3. When the 嘷
B button is pressed during the
chronograph measurement, the split or lap time is
displayed for 10 seconds, after which the running
display continues.
(4. When the 嘷
B button is pressed in the stop state,
the chronograph mode is switched to the reset
state.
Measurement time range: 0 hours 00 minutes
00 seconds 00 to 23 hours 59 minutes 59 seconds
(24-hour system)
• A measurement over 24 hours is automatically
stopped in the reset state
Split Time and Lap Time
Split time: time elapsed from the starting point to an
intermediate point
Lap time: time elapsed in a particular section
C. Chrono-Memo Function
Each time a series of start, stop and split time
measurement is performed in the chronograph mode,
the memo number is increased by one. The time
measurement and the time when the measurement
was finished are recorded as a chrono-memo. This
memo can be recalled after the final measurement.
Notes
• 00 to 99 memo numbers are available, but the
number of memos that can be recalled after the
measurements, is a maximum of 10 (No. 0-8 and
the final stop data).
• The memos are erased at the start of the next
chronograph use, or by the all reset operation,
refer to the ALL RESET OPERATION section. If
necessary, data should be recorded separately.
D. Recalling the Chrono memos
The same procedure is used to recall split time
memos and lap time memos.
1. Press the 嘷B button in the reset state during the
chronograph mode (split time measurement
chronograph or lap time measurement), then start
memo display (memo No. 00) is activated. The
chronograph start time (00’00”00) and the
operation time (current time when lap or split time
is measured) are displayed alternately for 1.5
seconds each.
2. By pressing the 嘷
B button repeatedly, memos No.
01 to No. 08 and the last stop memo can be
recalled. (For any memo, the elapsed time and
the time when the measurement has finished are
displayed alternately for 1.5 seconds each)
3. When the 嘷
B button is pressed after the last stop
memo is called, the display returns to the reset
state. (By pressing the 嘷
B button for 2 seconds or
more with a memo recalled, the display also
returns to the reset state.)
(Notes)
• If the number of memos including the start memo
is over 10 only memos No. 00 (start memo) to
No. 08 and the last stop memo can be recalled.
Memos No. 09 and subsequent memos cannot be
recalled.
E. Split Time/Lap Time Conversion Function
After the split time measurement is completed,
when the memo is recalled in the lap time
measurement chronograph mode, the split time will
be converted to the appropriate lap time.
The conversion from lap time to split time can be
performed in the same manner.
ALL RESET OPERATION
After replacement of the battery or in case of
incorrect display and operation (for example, the
display is turned off or the alarm continues to
sound) as a result of the watch being subject to a
strong impact, perform the ALL RESET
OPERATION as follows:
1. Pull the crown out to position (1).
2. Press the 嘷
A , 嘷B and 嘷M buttons simultaneously.
(When these buttons are depressed, the display
is turned off.)
3. Release the buttons. (Display of all parts is
turned on.)
4. Press the crown back into place. (At the same
time, the confirmation sounds for 2 seconds.) The
ALL RESET OPERATION is finished.
5. Then set the time correctly.
USING THE CALCULATOR RING*
The following points should be considered while
using the watch.
• Use the calculator as an approximate
measurement device.
• The scale is not defined any particular unit of
measure.
Calculator
1) Elapsed-time calculations
Example: How long will it
take a car travelling 80kph
to go 400 kilometres?
Calculation: Align 80 on
the outer scale with the
speed index (䊱) mark on
the inner scale. The
position on the outer scale at 40 will now be lined
up with 5:00 (5 hours) on the inner scale.
*Note that the calculator ring is not equipped on
some models.
2) Speed calculations
Examples: If a car goes
180 km in 2 hours 30
minutes, how fast was the
car travelling?
Calculation: Align 18 on
the outer scale with 2:30
on the inner scale. The
Speed index (䊱) mark will now be lined up with
72 (km/hr) on the outer scale.
3) Distance calculations
Example: How far will a
car go if it travels at 60kph
for 1 hour 20 minutes?
Calculation: Align 60 on
the outer scale with the
speed index (䊱) mark on
the inner scale. The
position on the inner scale at 1:20 will now be lined
up with 80 (km) on the outer scale.
4) Fuel consumption (litres/hr) calculations
Example: If a car travels
5 hours and uses 30 litres
of fuel, how many litres of
fuel per hour does the car
use?
Calculation: Align 30 on
the outer scale with 5:00
on the inner scale. The speed index (䊱) mark will
now be lined up with 60 (6 litres/hr) on the outer
scale.
5) Fuel consumption (litres) calculations
Example: How many litres
of fuel does the car need
to travel 5 hours if it uses
7 litres per hour?
Calculations: Align 70 on
the outer scale with the
speed index (䊱) mark on
the inner scale. The position on the inner scale at 5:00
will now be lined up with 35 (litres) on the outer scale.
6) Travel (time) calculations
Example: If a car has 40
litres of fuel and burns it at
a rate of 8 litres per hour,
how many hours will the
car be able to travel?
Calculations: Align 80 on
the outer scale with the
speed index (䊱) mark on the inner scale. The
position on the outer scale at 40 will now be lined
up with 5:00 (5 hours) on the inner scale.
7) Kilometre/mile conversions
• Use this feature to
convert between
kilometres and miles.
Example: One mile equals
how many kilometres?
Calculations: Align STAT
(䊱) (mile) on the inner
scale with the 10 on the outer scale. At this position
the km mark (䊱) will point to 1.6 on the outer scale.
PRECAUTIONS
1. Resistance to water
Check the following chart to determine the water
resistant properties of this watch.
2. Avoid temperature extremes
Avoid leaving your watch in direct sunlight or in
extremely warm locations for long periods of time.
• This will cause malfunctioning and shorten the life
of the battery. Do not leave your watch for long
periods of time in extremely cold places.
• This may cause your watch to gain or lose time.
• Place your watch on your wrist to restore its original
accuracy should it begin to gain or lose time.
Water resistance
3. Avoid strong shock
This watch will withstand the bumps and jars
normally incurred while playing and during sports
activities. Avoid dropping your watch on the ground
or otherwise imparting severe shock to it.
4. Avoid strong magnetic fields
Keep your watch out of the immediate vicinity of
strong magnets. Generally, your watch is not
affected by magnetic fields from such household
appliances as television sets and stereo equipment.
5. Avoid harmful chemicals, solvents and gases
Avoid wearing your watch in the presence of strong
chemicals, solvents and gases. If your watch comes
in contact with materials such as gasoline, benzine,
paint, discolouration, deterioration or damage to the
case, band and other components may occur.
6. Keep your watch clean
It may become difficult to pull out the crown due to
dirt and dust getting caught between the crown and
the watch case when the watch is worn for long
periods of time. To help prevent this happening, turn
the crown freely back and forth occasionally while it
is in the normal set position. Wipe off any water and
moisture that adheres to the case, glass and band
with a soft, clean cloth. Any dirt left on the case or
band may cause skin rash.
A watchband will easily become soiled with dust and
perspiration because it is in direct contact with the
skin. Even a stainless or gold plated band may
begin to corrode if it has not been cleaned for a
long period of time. Mesh bands, because the
meshes are very fine, will lose their particular
“flexibility” if they are left soiled for a long time.
Metal watchbands are usually washed with a brush
in mild, soapy water and well wiped with a soft,
absorbent cloth to make sure all water is removed.
Pay attention to prevent any water from getting
inside your watch when the band is washed.
7. Periodic inspection
Getting your watch checked once every year or two
is recommended to ensure long use and troublefree operation.
8. Be sure to keep the batteries out of reach of
infants and small children. Should accidental
ingestion occur, consult a doctor at once.
