Operation
Once installed, operating the RIB-600Analog radio receiver requires no human contact.
Portable, base station or mobile 2-way radios can deliver voice messages directly to a PA
system with a simple press of the PTT button for either live or recorded playback. This
section describes the subtle differences in operation for various RIB-600Analog options and
installations.
4.1
Basic Operation
Basic operation is defined as a RIB-600Analog receiver programmed on a dedicated radio frequency with a QC or DQC code.
The receiver is also programmed for 50% Audio Level and a pre-announce tone.
1. Move to an area that is away from any PA system speaker to prevent feedback.
2. Be sure the microphone on the calling radio is pointed away from any PA system speaker.
3. Set the portable, base station, or mobile radio to the RIB-600Analog channel.
4. Monitor the channel before transmitting to be sure there are no other radio users on the RIB-600Analog frequency.
5. Press and hold the PTT button and pause for about 1 second, allowing the pre-announce tone to be heard.
6. Speak into the radio microphone to broadcast your message over the PA system speakers. If other radios are operating
on the RIB-600Analog channel they will also hear your message.
7. Release the PTT button when your message is complete.
8. Return the portable, base station, or mobile radio to the normal operating channel.
4.2
DTMF and Selcall Paging
To access the RIB-600Analog receiver the 2-way radio must be programmed to send the correct DTMF or Selcall code. The
user simply presses the 2-
way radio’s PTT and speaks while on the RIB-600Analog channel. Only 2-way radios programmed
to send the correct DTMF or Selcall code on the RIB-600Analog channel can access the PA system.
1. Move to an area that is away from any PA system speaker to prevent feedback.
2. Be sure the microphone on the calling radio is pointed away from any PA system speaker.
3. Set the portable, base station, or mobile radio to the RIB-600Analog channel.
4. Monitor the channel before transmitting to be sure there are no other radio users on the RIB-600Analog frequency.
5. Press and hold the PTT button.
6. Wait until the entire DTMF or Selcall code has been sent, and then an additional 1 second for the pre-announce tone.
7. Speak into the radio microphone to broadcast your message over the PA system speakers. If other radios are operating
on the RIB-600Analog channel they will also hear your message.
8. Release the PTT button when your message is complete.
9. Return the portable, base station, or mobile radio to the normal operating channel.
With DTMF or Selcall Paging operation:
Once the RIB-600Analog receiver has decoded the correct DTMF or Selcall code any radio on the RIB-600Analog
channel can talk over the speaker without the need for DTMF or Selcall paging.
After a DTMF or Selcall code has been successfully decoded, the programmable Paging Reset Time sets the length
of time the RIB-600Analog receiver can go without receiving a signal before DTMF or Selcall is once again required
for access. Factory default Paging Reset Time is 10 seconds.
DTMF or Selcall paging can be used in conjunction with QC or DQC for added security. The 2-way radio and the
RIB-600Analog receiver must be programmed for the same QC or DQC code
.
