Check the battery manufacturer’s recommended operating
conditions for disposable batteries used in your processor.
Wireless communication link
The remote control/remote assistant wireless communication
link operates in the 2.4 GHz ISM band using GFSK (Gaussian
frequency shift keying) on 5 channels. The link uses a
proprietary bi-directional communication protocol and
operates over a distance of up to 2 metres from the processor.
When interference is present, the wireless communication link
switches between the 5 channels to find a channel where the
interference least affects the operation of the link. The
remotes indicate via their displays when the processor is not
within operating distance, and when the link has been
interrupted due to interference (see the relevant remote user
guide for more information).
