AQUATIC AND OUTDOOR ACTIVITIES
The watch is water-resistant up to 50 meters. The chest belt is splash
proof, and should not be worn for underwater activities, as the heart
rate transmission cannot occur under water. Refer to the table for
proper guidelines.
When using the watch for aquatic or outdoor sports activities, observe
the following guidelines:
• Do not press the keys under water or with wet fingers.
• Rinse with water and mild soap after use.
• Do not use in hot water.
BATTERIES
Both the watch and the heart rate chest belt use 1 x CR2032 3V battery.
Both are already installed. See the table below for battery warnings.
