1.3 Paging the Loudmouth®receiver and PA speaker
The Loudmouth®receiver and PA speaker can be paged with 2-way radios programmed for Quiet Call (CTCSS), Digital Quiet
Call (DCS), 2-Tone Paging, DTMF, or Selcall paging formats. Each format offers a unique method of paging the Loudmouth®
receiver and PA speaker.
Refer to the Programming section of this manual for specific instructions on programming your Loudmouth®receiver and PA
speaker to one of these selective signaling formats.
Ritron strongly recommends operation of the Loudmouth®receiver and PA speaker
with one of the following selective signaling formats enabled.
Paging the Loudmouth®with Quiet Call (CTCSS) only:
To page the loudspeaker a user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth®
channel.
Your 2-way radio must be programmed for a channel dedicated to Loudmouth® operation. Only those radios
programmed with the Loudmouth® channel will be able to access the loudspeaker.
The 2-way radio’s Loudmouth® channel and the Loudmouth® receiver must be programmed for the same QC code.
All Ritron radios offer 50 different field-programmable QC codes from which to choose.
Paging the Loudmouth®with Digital Quiet Call (DCS) only:
To page the loudspeaker a user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth®
channel.
Your 2-way radio must be programmed for a channel dedicated to Loudmouth® operation. Only those radios
programmed with the Loudmouth® channel will be able to access the loudspeaker.
The 2-way radio’s Loudmouth® channel and the Loudmouth® receiver must be programmed for the same DQC code.
All Ritron radios offer 104 different field-programmable DQC codes from which to choose.
Paging the Loudmouth®with 2-Tone Paging:
To page the Loudmouth® the 2-way radio must first send the correct 2-Tone Paging code. Once access to the
loudspeaker is accomplished, the user simply presses the 2-way radio’s PTT and speaks while on the Loudmouth®
channel. After a period of inactivity the Loudmouth® is automatically reset, and will then require the correct 2-Tone
Paging code to re-gain access.
Only 2-way radios programmed to send the correct 2-Tone code on the Loudmouth®channel can access the
Loudmouth®wireless PA speaker. However, once access is gained, any 2-way radio that operates on the
Loudmouth®channel can access the loudspeaker up until the time that the Loudmouth®has automatically reset.
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth® receiver must
be programmed for the same QC or DQC code.
Paging the Loudmouth®with DTMF or Selcall:
To page the Loudmouth® the 2-way radio must first send the correct 3-7 digit DTMF or Selcall code. Once access to
the loudspeaker is accomplished, the user simply presses the 2-way radio’s PTT and speaks while on the
Loudmouth® channel. After a period of inactivity the Loudmouth® is automatically reset, and will require the DTMF or
Selcall code to re-gain access.
Only 2-way radios programmed to send the correct 3-7 digit DTMF or Selcall code on the Loudmouth®channel can
access the Loudmouth®wireless PA speaker.
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth® receiver must
be programmed for the same QC or DQC code.

Section 1 Getting Started 4
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.
1.4 Compatibility with other RITRON model radios
The Loudmouth®model LM-600Analog receiver and PA speaker can operate on both VHF and UHF business band
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
radios.

1.5 Determine the volume setting
Selecting the correct volume level is critical to the performance of the Loudmouth®receiver and PA speaker. Carefully consider
the following before deciding on the appropriate volume setting. Refer to the Programming section of this manual for specific
instructions on programming the Volume Level.
Ambient noise level should be considered first when selecting the volume level.
Increasing the volume level in an effort to cover a wider area will result in:
Undesirably high volume when near the speaker.
Low volume at the outer edges of the coverage area.
A calling radio must be a greater distance from the Loudmouth®speaker to prevent feedback. (Feedback is the
result of Loudmouth®speaker audio getting into the calling radio’s microphone.)
When coverage of a large area is required, additional Loudmouth®speakers may be necessary for satisfactory
performance. See the Installation section of this manual for details on how to install 2 speakers using a single Loudmouth®
receiver, or multiple receivers and speakers.
1. Refer to the horizontal shaded bars on the chart below to
determine the sound level that best represents your location. This
should be the ambient, or average sound level. We will consider
the maximum sound level when we locate the speaker.
2. Estimate the maximum distance (in feet) that the loudspeaker
must be heard. Locate that distance on the chart below and
follow it up to find the line that is in the middle of your shaded bar.
This line indicates the optimum Loudmouth®volume level setting.

Ritron will begin manufacturing narrowband compatible Loudmouth®starting in December 2012. At that time, customer
orders will begin to be filled with radios manufactured for FCC narrowband compatibility. Specifically, table frequencies will
be converted to narrowband. Since Part 15 receivers are not subject to the narrowband mandate, you will still be able to
set the Loudmouth®for wideband operation via field programming (See Section 3.6 –Field Program Advanced Feature
Codes), or by using the PC Programmer. These radios will be clearly marked as “FCC Narrowband Compatible”.

Section 2 Installation 7
2 Installation
Proper installation of the Loudmouth®wireless PA speaker is critical to the performance and
overall satisfaction with your system. With careful consideration and planning Loudmouth®
can cover up to 7500 square feet with a single speaker, and can cover an even wider range
with multiple speakers and receivers. The actual coverage area is subject to factors such as
ambient noise level, obstructions and radio range. This section will help you plan an
installation that is best suited for your environment.
2.1 Selecting the PA speaker location
Speaker location is critical to the performance of the Loudmouth® receiver and PA speaker. Consider the following factors
before selecting a speaker location.
The speaker can be installed either indoors or outdoors.
Be sure there is a convenient source of 110VAC power for the RPS-1B power cube and that the radio receiver box can be
located inside, out of the elements. The speaker has a 25 ft. cable, if you need more a standard RCA phono cable
extension can be used (ie. Radio Shack Catalog #: 4202362).
The speaker should not be in an area where the 2-way radio user addressing the speaker will typically be located. If the
radio user is too close to the Loudmouth®speaker, feedback can occur due to loudspeaker audio getting into the radio
microphone. This is a problem related to the 2-way radio, not the Loudmouth®speaker. The use of the Record & Play
feature will eliminate this problem.
The speaker must be located at least 10 feet above head level.
At near range the Loudmouth®speaker is capable of sound levels that can cause permanent
hearing loss and should never be installed in a location where a person could be directly in
front of the speaker.
Install the Loudmouth® speaker close to the noisiest area you plan to cover.
If there is an area with a significantly higher ambient noise level, the Loudmouth® speaker should
be located as close as possible to this area. The speaker volume must be 6 db higher than the
ambient noise level in order to be heard. If the speaker is not close to the highest source of noise,
the volume level will be too loud for the quieter areas.

Section 2 Installation 8
The Loudmouth®speaker should be mounted as high as practical and pointed toward
the farthest location you need to cover.
Large obstructions will significantly reduce the coverage area.
Do not place the speaker behind large, tall objects.
