After Exercising
1. Carefully wash the transmitter with a mild soap and water solution.
2. Rinse it with pure water.
3. Dry the transmitter carefully with a soft towel.
4. Store the transmitter in a clean and dry place. Dirt impairs the
conductivity and functioning of the transmitter. Sweat and moisture can
keep the electrodes wet and the transmitter activated, which shortens
battery life.
