Acoustic signalling
It is possible to select between three modes of PTT acoustic signalling and network
indication for convenient radio operation. Various modes of acoustic signalling are
activated by settings in the speaker microphone memory. Last set signalling mode
remains when radio terminal is switched off and on again. Selected mode of
acoustic signalling is indicated by appropriate number of tones by each switching
on the radio with connected speaker microphone.
