Sportline DUO 1025 manual Replacing the Chest Transmitter Battery

REPLACING THE CHEST TRANSMITTER BATTERY

The Sportline Duo 1025 features a wireless heart rate transmitter, powered by a CR2032 3v Lithium battery. Under normal conditions you can expect to get approximately 300-400 hours of heart rate transmitter use with a fresh battery. To replace the battery:

1.Using a coin, turn the battery door counter clockwise until the door comes free of the watch.

2.Take care not to damage the O-ring seal for the battery compartment and carefully remove the old battery.

3.Place a new battery in the battery compartment with the positive (+) side toward the battery door.

4.Place the battery door over the opening and tighten it down by using a coin and turning in a clockwise direction.

5.If the O-ring has been damaged, replace it before reinstalling the battery door. Most jewelers and watch shops should have replacement O-ring seals.

NOTE: Extreme care should be taken when replacing the battery to ensure the unit remains fully water resistant. Failure to properly replace the battery and correctly seal the unit may cause the unit to become damaged and may void the warranty.
