Using the Polar S810 in a water environment
Your Polar S810 is water resistant to 50 metres/ 160 feet.
Heart rate measurement in a water environment is technically demanding
for the following reasons:
•
Pool water with a high chlorine content and seawater may be very
conductive and the electrodes of Polar transmitter may get short
circuited and ECG signals cannot be detected by the transmitter unit.
• Jumping into the water or strenuous muscle movement during
competitive swimming may cause water resistance that shifts the
transmitter on the body to a location where it is not possible to pick up
ECG signal.
• The ECG signal strength varies depending on the individual’s tissue
composition and the percentage of people who have problems in heart
rate measuring is considerably higher in a water environment than in
other use.
Batteries
Polar T61 transmitter
The estimated average battery life of the Polar T61 transmitter is 2500
hours of use. Contact your distributor/ dealer for a transmitter
replacement. Polar recycles used transmitters. See your Customer Care
Charter for detailed instructions.
Polar S810 wrist receiver
The estimated average battery life of the Polar S810 wrist receiver is
2 years in normal use (2h/ day, 7 days a week). Note also that excessive
use of the backlight and the alarm signals will use the battery more
rapidly. Do not open the Polar wrist receiver yourself. To ensure the
water resistance properties and the use of qualified components, the
wrist receiver battery should be replaced only by an authorised
Polar Service Centre. At the same time a full periodic check of the
Polar heart rate monitor will be done.
Service
Should your Polar heart rate monitor need service, see Customer Care
Charter to contact an authorised Polar Service Centre.
Water resistance cannot be guaranteed after unauthorised service.
