To start an elapsed time operation while in the Timekeeping Mode
1. In the Timekeeping Mode, press B to start elapsed time measurement.
• Elapsed time measurement will start internally when you press B, but timing will
not appear for about one second.
• The elapsed time measurement will not start if you press B in the Timekeeping
Mode while either of the following conditions exists.
While an alarm is sounding
While the watch is changing from one date to the next (at midnight)
2. Press B to stop elapsed time measurement.
• You can restart and stop elapsed time measurement as many times as you like by
pressing B.
• The center dial hand rotates during the first 60 seconds only, and then stops. When
elapsed time measurement is stopped (by pressing B), the center dial hand jumps
to the 1/20 second indication (which is kept internally).
• Stopping a timing operation will cause the stopwatch second hand to stop at the
elapsed time seconds position. It will remain there if there is no distance value input.
If a distance value is input, the stopwatch second hand will then move to average
speed indication after about two seconds. After that it will move back to the elapsed
time second position.
• After you are finished measuring elapsed time, press D to reset the stopwatch to all
zeros.
•
To return to the Timekeeping Mode, press
D
while the stopwatch is reset to all zeros.
To measure lap times
1. In the Timekeeping Mode or the Stopwatch Mode,
press B to start an elapsed time measurement
operation.
2. Press D to display the current lap time.
• Each press of D displays the current lap time up to
that point.
• The lap time will remain displayed for about two
seconds.
• Pressing D to display the current lap time also will
start timing of the next lap. This means that the
stopwatch does not maintain the total elapsed time or
total cumulative time in this case.
• The stopwatch will continue to time the next lap
internally, even while the current lap time is displayed.

• If a distance value is input, performing a lap time operation will cause the
stopwatch second hand to stop at the current lap time for about two seconds. The
stopwatch second hand will then move to the speed indication of the lap for about
two seconds. After that it will move to the ongoing elapsed time operation position.
3. Press B to stop the stopwatch.
• This will cause the final lap time to appear on the display.
• Press D to reset the stopwatch.
Average Speed
You also can input the distance of the course or a particular segment of the course of
the race you are watching. That distance is used along with the elapsed time,
cumulative elapsed time, or lap time measured by the watch to calculate and display
the average speed for the course or segment.
The average speed that appears for an elapsed time, cumulative elapsed time, or lap
time is calculated based on the times described below.
Elapsed time: Time from the point the stopwatch operation is started up until it was
stopped.
Cumulative elapsed time: Total time from the point the cumulative elapsed time
operation is started up until it was stopped. Does not include any time when the
stopwatch operation was paused.
Lap time: Time of each particular lap.
• Never operate the stopwatch while operating a motor vehicle. Doing so is very
dangerous and can cause an accident.
• The initial factory default setting for the distance value is 1.0.
• For information about inputting a distance, see “To specify a course or section
distance”.
Average Speed Indication
The stopwatch second hand will indicate the average
speed value after you stop an elapsed time measurement
or display a lap time. The center dial hand points to
SPEED (SPD) while the average speed is being indicated.
Stopping an Elapsed Time or Cumulative Elapsed
Time Measurement
Two seconds after you stop an elapsed time
measurement operation by pressing B, the stopwatch
second hand will indicate the speed for two seconds. After
that, the stopwatch second hand will move back to the
elapsed time seconds position.
Lap Time Measurement
Two seconds after you stop a lap time measurement
operation by pressing D, the stopwatch second hand will
indicate the speed for two seconds. After that, the
stopwatch second hand will move to the ongoing elasped
time operation.

• If the value you input for the distance was in kilometers,
the indicated speed values will show kilometers per
hour. If the value you input was in miles, it will show
miles per hour. Note that the watch does not have a
setting for specifying kilometers or miles.
• The average speed is indicated as a value from 0 to
350, in increments of 10. The ones digit is rounded off.
• Either of the following will cause the stopwatch second
hand to indicate OVER, which indicates that speed
cannot be calculated.
When the speed calculation produces a value
greater than 350
When a displayed elapsed time or cumulative
elapsed time is 60 minutes or greater
When a displayed lap time is 60 minutes or greater
(Average speed calculation will resume when timing
of the next lap is performed.)

To specify a course or section distance
1.In the Stopwatch Mode, hold down A for about three
seconds until the center dial hand moves to DIST.
• This is the distance setting mode.
2.Use D and B to specify the course or section
distance.
• Use B to move the stopwatch second hand and
specify the value to the left of the decimal place. You
can specify a value from 0 to 14.

specify a value from 0.0 to 0.9.
• It makes no difference whether the value you specify
represents kilometers or miles.
3.Press A to exit the setting screen.
• To disable speed display, specify a distance value of 0.0.

Alarm
When the alarm is turned on, the alarm sounds when the
alarm time is reached.
• Whenever you enter the Alarm Mode, the stopwatch
second hand will move to the ALM position. The center
dial hand will move to the alarm’s current ON/OFF
status while the hour, minute and 24-hour hands
indicate the current alarm time setting.
• All of the operations in this section are performed in the
Alarm Mode.
To set an alarm time
1.In the Alarm Mode, hold down A for about three
seconds until the watch beeps and the center dial hand
moves to ON (alarm on).
• This is the setting mode.
• Setting the alarm time causes the alarm to turn on
automatically.

2. Use D (+) and B (–) to change the alarm time setting.
• Each press of either button changes the setting by one minute.
3. After setting the alarm time, press A to exit the setting mode.
• As you set the alarm time, take care to ensure that the 24-hour hand also is at the
correct position.
Alarm Operation
The alarm tone sounds at the alarm time for 10 seconds, regardless of the mode the
watch is in.
• Alarm operations are performed in accordance with the Timekeeping Mode time.
• Pressing any button stops the alarm tone operation.
To toggle an alarm on and off
In the Alarm Mode, press A to toggle the alarm setting indicated by the center dial
hand ON or OFF.
Adjusting the Home Positions
If you notice that the watch hands are not indicating 12 o’clock, ON/OFF settings, or
other indicator settings correctly, you can adjust the “home positions” of the hands
manually to correct them.
To adjust the home positions
1.In the Timekeeping Mode, as you hold down A, hold
down C for about three seconds until the watch beeps.
• This indicates that the watch is in the time and day
home position adjustment mode.
• The center dial hand is in the proper home position if
it moves to “0”. If it doesn’t, use
D
to move the center
dial hand to “0”.
• The stopwatch second hand also is in the proper
home position if it moves to 12 o’clock. If it doesn’t,
press B to move it to 12 o’clock.

2.After confirming that the center dial hand and stopwatch
second hand are both at the proper home positions,
press C.
This will switch to hour hand and minute hand home
position adjustment.
• The hour hand and minute hand are at their proper
home positions if they both move to 12 o’clock, and if
the 24-hour hand is pointing at hour 24. If the hands
are not positioned correctly, use D (+) and B (–) to
move all three hands to their proper home positions.
• The 24-hour hand moves in accordance with the hour,
minute, and second settings. As you set the time, take
care to ensure that the 24-hour hand also is at the
correct position.
