Thermometer Precautions
Temperature measurements are affected by your body temperature (while you are wearing the watch),
direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch
from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the
case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding
temperature.

Using the Stopwatch
You can use the Stopwatch Mode to measure, record, and recall lap times and split times. Up to 100 lap
times can be stored in memory and a record of the fastest lap time is also maintained. Though no more
lap times are stored after 100 times are in memory, the fastest lap time continues to be updated as
required. Starting a new elapsed time operation clears all of the memories (including fastest lap time).
What is a lap time?
A lap time is the time elapsed over a specifi c segment of a race.
Example: Car race on an oval track
Lap 1
Lap 2
Lap 3

What is a split time?
A split time is the time elapsed from the beginning of a race to any point within the race.
Example: During a marathon, the time at 10km, 20km, etc.
