Detach the transmitter connector from the strap and rinse both under running water after every use. Dry the connector with a soft towel. Never use alcohol or any abrasive material (steel, wool or cleaning chemicals).
Wash the strap regularly in a washing machine at 40ºC/104ºF or at lest after every fifth use. This ensures reliable measurement and maximizes the life span of the transmitter. Use a washing pouch. Do not soak, spin-dry, iron, dry clean or bleach the strap. Do not use detergent with bleach or fabric softener. Never put the transmitter connector in the washing machine or dryer!
Dry and store the strap and the transmitter connector separately. Wash the strap in a washing machine before long-term storage, and always after use in pool water with high chlorine content.
Dirt impairs the elasticity and functioning of the transmitter.
Sweat and moisture may keep the electrodes wet and the transmitter activated. This will shorten the battery life.
If the snaps are often left moist, the resulting oxidation could hinder the functioning of the transmitter.
