User manual

Keep the batteries away from children. If swallowed, contact a doctor immediately. Batteries should be

disposed of properly according to local regulations.

CHANGING HEART RATE SENSOR BATTERY

To change the battery of the heart rate sensor yourself, carefully follow the instructions below:

When changing the battery, make sure the sealing ring is not damaged, in which case you should replace it

with a new one. You can purchase the sealing ring/battery kits at well-equipped Polar retailers and authorized

Polar Services. In the USA and Canada, the additional sealing rings are available at authorized Polar Service

Centers. In the USA the sealing ring/battery kits are also available at www.shoppolar.com.

When handling a new, fully charged battery, avoid clasp-like contact, i.e. simultaneously from both sides, with

metal or electrically conducting tools, like tweezers. This may short circuit the battery, causing it to discharge

more rapidly. Typically, short circuiting does not damage the battery, but it may decrease the capacity and the

lifetime of the battery.

1. Using a coin, open the battery

cover by turning it coun-

terclockwise to OPEN.

2. Insert the battery (CR 2025)

inside the cover with the positive

(+) side against the cover. Make

sure the sealing ring is in the

groove to ensure water res-

istance.

3. Press the cover back into the con-

nector.

4. Use the coin to turn the cover

clockwise to CLOSE.

Danger of explosion if the battery is replaced with wrong type.
