Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
To change the Daylight Saving Time (summer time) setting
1.In the Timekeeping Mode, hold down A for about three
seconds until the city code flashes on the upper display.
This is the setting mode.
2.Press C. This will display the DST setting screen.
3.Use D to toggle the DST setting on and off.

12-hour and 24-hour timekeeping
• With the 12-hour format, the PM indicator appears on the lower display for times in
the range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
the PM indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.

Stopwatch
You can use the stopwatch to measure elapsed time, lap
times and split times. If you specify a distance value, the
stopwatch also will calculate and display speeds.
• The digital display range of the stopwatch is 99 hours,
59 minutes, 59.999 seconds. The stopwatch continues
to run until you stop it. If it reaches the above limit, it will
restart the time measurement from zero.
• The stopwatch operation continues even if you exit the
Stopwatch Mode. If you exit the Stopwatch Mode while a
stopwatch operation is in progress, the segments of the
speed indicator will appear and disappear sequentially
as stopwatch seconds are counted.
• All of the operations in this section are performed in the
Stopwatch Mode, which you enter by pressing C (page
E-7).

Important!
• Check to make sure that the speed hand is not moving before you perform any
Stopwatch Mode button operation.
Specifying a Distance Value
You can use the procedure below to specify a distance value, if you want. If you
specify a distance value, the watch will calculate and indicate speed for certain
stopwatch operations.
• The distance value represents kilometers, miles, or any other distance unit you want.
Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or 10.0
miles.
• No speed calculation is performed when 0.0 is specified as the current distance
value.
• For lap time readings, you can specify either the lap distance (when all the laps are
the same distance) or the total race distance.
• For split time readings, you can specify the total race distance only. Though the
watch will indicate a speed each time you take a split reading, they will be based on
the total race distance, and so they will not indicate actual intermediate split speeds.
E-16
To specify a distance value
1.In the Stopwatch Mode, make sure the stopwatch is
stopped and reset to all zeros.
• If you need to reset the stopwatch to all zeros, press A.
2.Hold down A for about three seconds until the watch
beeps, DIST (
) appears in the upper display, and
the left digit of the current distance value setting flashes
in the lower display.
• This is the distance value setting mode.
3.Press C to move the flashing between the values on
the left side and right side of the distance value digit
decimal point.
4. While either the left or right distance value is flashing,
use D (+) and B (–) to change it.
• You can specify a distance value in the range of 0.1 to
99.9.
5. After specifying the distance value you want, press A
to exit the setting mode.

How speed is indicated
• While an elapsed time measurement operation is being
performed in the Stopwatch Mode, the watch will display
a speed value, which is calculated based on the
distance you specified and the elapsed time. The speed
is indicated by the speed indicator (100 to 1000) on the
left and the speed hand on the right.
• The speed indicator indicates the 100s digit value.
• 1000 is indicated when the speed exceeds 1,000.
• The speed hand indicates 10s digit value.
Example:
At a speed of 1,740, a pointer appears next to 1000 in the
speed indicator.
The speed indicator on the left indicates 700.
The speed hand on the right indicates 40.
• Speed can be indicated from 0 to 1998. OVER is
indicated by the speed hand when the speed exceeds
1998.

Time Measurement
You need to specify either lap time (page E-20) or split time (page E-22) measurement
before you start a stopwatch operation.
• If you want to measure total elapsed time, select split time measurement.
To specify lap time or split time readings
1. In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.
• Make sure that
(lap times) or (split times) is shown in the lower display.
• If you need to reset the stopwatch to all zeros, press A.
2. Press A to toggle between (lap times) and (split times) in the lower
display.

Elapsed Time Measurement
Use the following procedure to measure elapsed time, without taking lap time or split
time readings.
To perform elapsed time measurement
Select split time ( ) measurement and then perform the following button operations.
D Start ➝D Stop ➝ A Reset
• If you have a distance value (page E-15) specified for the current elapsed time
measurement, the speed indicator on the left and the speed hand on the right will
indicate the overall speed when you press D to stop the elapsed time operation.
• After pressing D to stop an elapsed time operation, you could press D again to
restart from the point where you left off.
