Ritron recommends the use of a dedicated channel frequency for Loudmouth
®
operation.
When operating on unique frequencies dedicated to loudspeaker operation:
Your 2-way radios must be programmed for a channel dedicated to loudspeaker operation.
Loudspeaker operation is limited to radios programmed with the dedicated Loudmouth
®
channel.
The use of 2-tone, DTMF, or Selcall paging to address the Loudmouth
®
is not required, but can still be used if
additional access security is desired.
Without 2-tone, DTMF, or Selcall paging the loudspeaker can be addressed by simply selecting the Loudmouth
®
channel on your 2-way radio and pressing the PTT button to talk.
You may need to license additional frequencies for your 2-way radios (not necessary when programmed for MURS
frequencies, see
Table F
in the Programming section).
When operating on your normal 2-way communication frequencies:
Messages broadcast on the Loudmouth
®
are also heard on your 2-way radios.
Loudspeaker messages are not possible when the channel is being used for 2-way communications.
The use of 2-tone, DTMF, or Selcall paging is required to address the Loudmouth
®
, otherwise all 2-way
communication is heard on the loudspeaker.
Any user on your 2-way channel can broadcast over the loudspeaker once it is activated, even if their 2-way radio is
not programmed with the correct 2-tone, DTMF or Selcall paging code.
There is no need to license additional frequencies.

Compatibility with other RITRON model radios
The Loudmouth
®

frequencies. Loudmouth
®
can be accessed with radios programmed for Quiet Call (CTCSS), Digital Quiet Call (DCS), 2-Tone
Paging, DTMF, or Selcall paging formats. The following chart can be used to determine compatibility with existing Ritron
