the battery and replace it with a new one. Be careful not to damage the threads of the back cover.
3. Place the positive (+) side of the battery against the cover and negative (-) side toward the training
computer.
4. The sealing ring of the battery cover is also attached to the cover. Replace the sealing ring if it is
damaged. Before closing the battery cover, make sure that the sealing ring is undamaged and is placed
correctly in its groove.
5. Put the battery cover in its place and turn the cover clockwise with a coin to CLOSE position. Make sure
that the cover is closed properly!
Excessive use of the backlight drains the training computer’s battery more rapidly. In cold conditions, the
low battery indicator may appear, and disappear again when you return to a warmer environment. To
ensure the maximum lifespan of the battery cover, open it only when changing battery. When changing the
battery, make sure the sealing ring is not damaged, in which case you should replace it with a new one.
Battery kits with sealing rings are available at well-equipped Polar retailers and authorized Polar Service
Centers. In the USA and Canada, sealing rings are available at authorized Polar Service Centers only.
Keep batteries away from children. If swallowed, contact a doctor immediately. Batteries should be properly
disposed of according to local regulations.
