Question 161

How is a specific group of stations selected on a DMR digital voice transceiver?

  1. By retrieving the frequencies from transceiver memory
  2. By enabling the group’s CTCSS tone
  3. By entering the group’s identification codeBonne réponse
  4. By inserting a five-pin, pre-programmed code plug

Explication

DMR routes audio by talkgroup, and a talkgroup is selected by its numeric identification code programmed into or entered on the radio. CTCSS tones belong to analogue FM, and the code plug is configuration data rather than a physical five-pin part.
