Receiving range of the heart rate monitor
Your heart rate monitor picks up the heart rate signals sent by the
chest strap transmitter within a range of 70 centimeters.
Your HR monitor receives the signals from the Speedbox within a
range of three meters.
Sensors on the chest strap
The entire chest strap consists of two components: the actual chest
strap and an elastic tension belt. On the inside of the chest strap
contacting the body, there are two rectangular, corrugated sensors.
Both sensors determine your heart rate ECG exactly and transmit
this to the heart rate monitor.
The digital transmission works almost without interference. Your HR
monitor only receives the signal from the corresponding transmitter.
There can be no interfering signals from other transmitters.
The chest strap is not compatible with analogue devices, such as
e.g. ergometers.
