2-Tone Paging
To access 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
™
will automatically reset, and will then require the
correct 2-Tone Paging code to re-gain access.
1. Move to an area that is away from the Loudmouth
™
speaker to prevent feedback.
2. Be sure the microphone on the calling radio is pointed away from the Loudmouth
™
speaker.
3. Set the portable, base station, or mobile radio to the Loudmouth
™
channel.
4. Monitor the channel before transmitting to be sure there are no other radio users on the Loudmouth
™
frequency.
5. Send the correct 2-Tone Paging code. Refer to your 2-way radio’s user manual to determine how you send
2-tone paging codes.
6. Wait until the entire 2-tone code has been sent.
7. Press and hold the PTT button and pause for about 1 second, allowing the pre-announce tone to be heard.
8. Speak into the radio microphone to broadcast your message over the Loudmouth
™
speaker. If other radios
are operating on the Loudmouth
™
channel they will also hear your message.
9. Release the PTT button when your message is complete.
10. If the radio PTT is pressed again before the Loudmouth
™
receiver has reset, the message will be heard on
the speaker without the need for a 2-tone Paging code.
11. Return the portable, base station, or mobile radio to the normal operating channel.
With 2-Tone Paging operation:
•
Once Loudmouth
™
receiver has decoded the correct 2-tone code any radio on the Loudmouth
™
channel can talk over the speaker without the need for 2-tone paging.
•
After a 2-tone code has been successfully decoded, the programmable Two-Tone Reset Time sets the
length of time the Loudmouth
™
receiver can go without receiving a signal before 2-tone is once again
required for access. Factory default Two-Tone Reset Time is 5 seconds.
•
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 .

Record and Play
(20 seconds of record time MAXIMUM)
When 2-way radios are used in the same area as the Loudmouth
™
speaker, feedback may result that can render
the system unusable. For those applications the Loudmouth
™
can be programmed to record the incoming
messages and play them back over the speaker when the PTT button is released on the 2-way radio. Set the
portable, base station, or mobile radio to the Loudmouth
™
channel.
1. Monitor the channel before transmitting to be sure there are no other radio users on the Loudmouth
™
frequency.
2. Press and hold the PTT button on your 2-way radio.
3. Speak into the radio microphone to record your message into the Loudmouth
™
receiver. If other radios are
operating on the Loudmouth
™
channel they will hear your message as you record it.
4. Release the PTT button when your message is complete.
5. The pre-announce tone will be heard and the Loudmouth
™
speaker will begin playing your recorded
message.
6. When finished, return the portable, base station, or mobile radio to the normal operating channel.
With Record and Play operation:
•
Recorded messages are limited to a maximum of 20 seconds.
•
Any of the selective signaling options can be used in conjunction with Record and Play.
•
The Loudmouth
™
receiver cannot record (buffer) an incoming message while in the process of playing
a message on the speaker.
