EFFECTIVE USE AND RANGE
The heart rate chest belt and watch have a maximum transmission range
of about 76 centimeters (30 inches). If the signal is weak, take the
following steps.
• Shorten the distance between the heart rate chest belt and watch.
• Re-adjust the position of the heart rate chest belt.
• Check the batteries. If they are low or exhausted, the range may
be less.
You can wear the receiver watch on your wrist or strap it to a bike or exercise
machine, as shown belo w.
AQUATIC AND OUTDOOR ACTIVITIES
The watch is water-resistant up to 50 meters. The chest belt is water-
resistant up to 10 meters, but should not be worn for underwater activities,
as the heart rate transmission cannot occur under water. Refer to the table
for proper use guidelines.
