Wash the strap regularly in a washing machine at 40ºC/104ºF or
at lest after every fifth use. This ensures reliable measurement and
maximizes the life span of the transmitter. Use a washing pouch.
Do not soak, spin-dry, iron, dry clean or bleach the strap. Do not use
detergent with bleach or fabric softener. Never put the transmitter
connector in the washing machine or drier!
Dry and store the strap and connector separately. Wash the strap
in a washing machine before long-term storage, and always after
use in pool water with high chlorine content. Keep the transmitter
in a cool and dry place. Do not store wet in non-breathing material,
such as a sports bag. Sweat and moisture keep the electrodes wet
and activated. Do not expose to direct sunlight for extended periods.
WearLink Transmitter Battery
The estimated average battery lifespan of the transmitter is 2 years
(usage: 1h/day, 7 days/week). If your transmitter stops working,
it might be due to the battery running out.
To change the battery, you need a coin, sealing ring and battery
(CR 2025).
4. Place the negative (-) side of the battery against the bottom and
the positive (+) side against the cover.
5. Put the cover on so that the arrow points to the OPEN position.
Make sure that the cover’s sealing ring is placed correctly in its
groove.
6. Gently press the cover deep enough so that its exterior surface is
on the same level as the connector’s surface.
7. Turn the cover with the coin clockwise so that the arrow on the
cover turns from OPEN to CLOSE. Make sure that the cover is
closed properly!
Note:
• In order to ensure the maximum life span of the connector’s
battery cover, open it only when you need to change the battery.
We recommend that you change the sealing ring of the battery
cover every time you change the battery. You can get the sealing
ring/battery kits from well-equipped Polar retailers and
authorized Polar Services. In the USA and Canada: Additional
sealing rings are available from an authorized Polar Service
Center only.
• Keep the batteries away from children. If swallowed, contact a
doctor immediately.
• Batteries should be disposed of properly according to local
regulations.
