With the following accessories you get the most out of your S725
Polar Cadence Sensor:
A wireless sensor that measures the speed at which
you turn the pedals of your bicycle.
IR Interface:
The Polar IR interface is designed for communication
between Polar heart rate monitors and Polar software
products. For infrared connection to your PC you need
a Polar IR interface if you do not have an IrDA port in
your PC.
Power Output Sensor:
The Polar Power Output system measures pedaling
power when cycling. It also measures left/right balance
(LRB describes the share of power output of left and
right as a percentage), pedaling Index (describes how
evenly power output was produced during a cycle
round), speed, cadence and distance. If you use the
Power Sensor, you do not need to mount any other
accessories on your bicycle.
Polar S725 offers you the possibility for
infrared communication with Polar training
analysis software. See the instructions from
the CD-ROM set.
