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.
STOPWATCH MODE
The Stopwatch Mode automatically saves the best five lap times in memory, along
with lap numbers. You can later recall the saved data using the “RESULT MODE”.
The Stopwatch Mode provides you with the following types of stopwatch capabilities.

Dual Stopwatch
Use the Dual Stopwatch to measure the times of two cars or runners at the same
time. You can also produce lap times for both and determine the difference between

The difference between the two times appears on the display for about four sec-
onds. After that, each lap time appears for about four seconds.
If the time of the second starter is faster than that of the first, the time difference is
displayed as a negative value.
If the time difference is 10 minutes or more, -- -- -- is displayed in place of the time.
If the times being compared are from different laps, the time difference is shown
without a plus or minus indication.
