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 or Selcall paging to address the Loudmouth
™
is not required, but can still be used if
additional access security is desired.
•
Without 2-tone 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 (not necessary with LM-V150 programmed for MURS
frequencies, see
Table 1
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 or Selcall paging is required to address the Loudmouth
™
, otherwise all 2-way
communication is heard on the loud speaker.
•
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 paging code.
•
There is no need to license additional frequencies.
