REPLACING THE BATTERY
The transmitter belt operates on a 3-Volt lithium cell, type: CR 2032. The average expected
battery life of the transmitter belt is 300 hours of use in ideal operating temperatures. To
replace the battery:
1. Insert a coin into the slot located on the battery compartment cover on the backside of the
transmitter belt.
2. Turn the coin counterclockwise until it is aligned with the open position marker, or even
slightly further for easy opening.
3. Remove the battery compartment cover. Ensure that the O ring and all surfaces are clean
and dry. Do not stretch the O ring.
4. Carefully remove the old battery.
5. Place the new battery into the battery compartment with the positive side facing up.
6. Replace the battery cover and turn clockwise until it is locked.
A short beep and a short green flash indicate that the new battery has been installed suc-
cessfully.
