It is only possible to communicate using the walkie−talkies when they are each set to the same channel and CTCSS/DCS code. The CTCSS/DCS codes are transmitted as inaudible signals together with the standard voice communication. When received, the voice communication signal is only transferred to the loudspeaker when the channel and CTCSS/DCS code set on the receiver are identical to that of those received (settings on the transmitter). If, by coincidence, another subscriber is using the same channel and CTCSS/DCS code, change to a free channel together with the party being called. 2xM Y/XP 3xM Y/XP Activate CTCSS code programming mode Select the CTCSS code and confirm it or Activate DCS code programming mode Select the DCS code and confirm it 1DCS: Digital Coded Squelch = Selective call 2CTCSS: Continous Tone Coded Squelch System = Selective call 55 Operating the Walkie−Talkies An exception here is CTCSS/DCS code 0 (zero).
