Ritron recommends the use of a dedicated channel frequency for LPA
operation.
When operating on unique frequencies dedicated to LPA operation:
•
Your 2-way radios must be programmed for a channel dedicated to LPA operation.
•
LPA-Series receiver operation is limited to radios programmed with the dedicated LPA channel.
•
The use of 2-tone or Selcall paging to address the LPA receiver is not required, but can still be used if
additional access security is desired.
•
Without 2-tone or Selcall paging the LPA receiver can be addressed by simply selecting the LPA
channel on your 2-way radio and pressing the PTT button to talk.
•
You may need to license additional frequencies (not necessary with LPA-V150 programmed for MURS
frequencies, see
Table 1
in the Programming section).
When operating on your normal 2-way communication frequencies:
•
Messages received by the LPA-Series receiver and broadcast on the wired PA system are also heard
on your 2-way radios.
•
LPA operation is 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 LPA receiver, otherwise all 2-way
communication is heard on the wired PA system.
•
Any user on your 2-way channel can broadcast over the wired PA system once the LPA receiver 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.

Compatibility with other RITRON model radios
The LPA-Series receiver is available in both VHF (LPA-V150, 150-165 MHz) and UHF (LPA-U450, 450-470 MHz)
business band frequencies. LPA receivers can be accessed with radios programmed for Quiet Call (CTCSS),
Digital Quiet Call (DCS), 2-Tone Paging, or Selcall paging formats. The following chart can be used to determine
compatibility with existing Ritron radios.
