Digital-analogue Mixed System
36
This is an example of Digital and analogue mixed
mode operation when introducing digital system
components into an existing analogue system. This
system primarily operates in analogue mode while
utilizing the digital features that communicate
between the digital radios.

Cloning Software Setup
•Set the Talk Back ON in the scan list setting for the
transceivers in Group C to transmit an analogue
signal when received from Groups A and B
• Set the same Scan List for analogue and Digital
CH
• Set the CH Type analogue for analogue CH and
CH Type Digital for Digital CH
