Paging the LPA-Series receiver

 

The LPA-Series receiver can be paged with 2-way radios programmed for Quiet Call (CTCSS), Digital Quiet Call 
(DCS), 2-Tone Paging, or Selcall paging formats.  Each format offers a unique method of paging the LPA receiver.   

 

Refer to the Programming section of this manual for specific instructions on programming your LPA receiver to one 
of these selective signaling formats.

Ritron strongly recommends operation of the LPA-Series receiver with one 
of the following selective signaling formats enabled. 

 

Paging the LPA-Series receiver with Quiet Call (CTCSS) only: 

 

To page the LPA receiver a user simply presses the 2-way radio’s PTT and speaks while on the LPA 
channel. 

 

Your 2-way radio must be programmed for a channel dedicated to LPA receiver

 

operation.  Only those 

radios programmed with the LPA channel will be able to access the loudspeaker. 

 

The 2-way radio’s LPA channel and the LPA 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 LPA-Series receiver with Digital Quiet Call (DCS) only: 

 

To page the LPA receiver a user simply presses the 2-way radio’s PTT and speaks while on the LPA 
channel. 

 

Your 2-way radio must be programmed for a channel dedicated to LPA receiver operation.  Only those 
radios programmed with the LPA channel will be able to access the loudspeaker. 

 

The 2-way radio’s LPA channel and the LPA 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 LPA-Series receiver with 2-Tone Paging: 

 

To page the LPA receiver the 2-way radio must first send the correct 2-Tone Paging code.  Once 
access to the LPA receiver is accomplished, the user simply presses the 2-way radio’s PTT and speaks 
while on the LPA channel.  After a period of inactivity the LPA receiver

 

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 LPA channel can access the 
LPA receiver.  However, once access is gained, any 2-way radio that operates on the LPA channel can 
access the LPA receiver up until the time that the LPA receiver has automatically reset. 

 

Can be used in conjunction with QC or DQC for added security.  The 2-way radio and the LPA receiver 
must be programmed for the same QC or DQC code.    

 

 

Paging the LPA-Series receiver with Selcall: 

 

To page the LPA receiver

 

the 2-way radio must be programmed to send the correct Selcall code every 

time the PTT is pressed.  The user simply presses the 2-way radio’s PTT and speaks while on the LPA 
channel.   

 

Only 2-way radios programmed to send the correct Selcall code on the LPA channel can access the 
LPA receiver.  

 

Can be used in conjunction with QC or DQC for added security.  The 2-way radio and the LPA receiver 
must be programmed for the same QC or DQC code
