Batteries
Transmitter
The estimated average battery life span of the transmitter is 1 year
(2h/ day, 7 days/ week). If your transmitter stops working, it might be
due to the battery running out. We recommend that you have the
battery replaced by an authorized Polar Service Center only.
You can, however, change the battery yourself by following the
instructions below. To change the battery, you need a coin, a sealing
ring and a battery (CR2025).
1. Open the connector's battery cover by turning it counterclockwise with
the coin from the CLOSE position to the OPEN position. The cover pops
out from its niche.
