DIGITALLY CODED

The new ONYX models stand out for their digital, coded transmission. This avoids disturbances during group training and prevents from the -cross talk effect-, as it is known in specialist jargon.

At the start of training, synchronisation takes place between the coded chest belt and the heart rate monitor. Consequently the watch only receives data from its own chest belt. The heart rate readings are converted into digital data packages and transmitted to the receiver in the watch. A -time coding & ID procedure- within ONYX models guarantees that data transmission is significantly more secure compared to analogue heart rate monitors.
