2 seconds.
• Pressing D in the Stopwatch Mode illuminates the display for about 2 seconds.
• The backlight of this watch employs an electro-luminescent (EL) light, which loses
its illuminating power after very long term use.
• Frequent use of the backlight shortens the battery life.
• The watch emits an audible sound whenever the display is illuminated. This does
not indicate malfunction of the watch.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The backlight automatically turns off whenever an alarm sounds.

About Laps and Splits
Lap Times
A lap time is the amount of time it takes for you to get from one point to
another during a race. When running on a track, for example, you can time
how long it takes you to complete each lap.
Split Times
A split time is the time from the start of a race until the point that the split is
measured. For example, you could measure split times to determine how
long it takes for you to get from the starting line to the 5-kilometer mark, the
10-kilometer mark, etc.
The Stopwatch Mode lets you measure elapsed time, lap
times, and split times. The range of stopwatch is 99 hours,
59 minutes, 59 seconds. You can use the EL backlight by
pressing D at any time while the stopwatch is operating.
The Stopwatch Mode also lets you store the lap times for
multiple laps in memory for later recall when you need
them.
This watch manages data according to RUN, which are
made up of multiple data records. All data stored from the
start of the stopwatch operation to the end of the stop-
watch operation makes up one RUN. Within a RUN, each
lap/split operation stores one record. The watch can hold
up to 500 data records in memory.
The final time recorded when you stop the stopwatch op-
eration is recorded as the final lap time.
The first hour of a stopwatch operation is measured in units of 1/100 second. After
that, elapsed time is measured in units of one second.
