1. 5-Tone is a non-proprietary signalling protocol that
allows the Icom radio to inter-operate with other
brands using the 5-Tone signalling.
2. This protocol also allows a mixed fleet operation.
3. It is faster than 2-Tone by employing a quick data
burst.
4. Customers are familiar with the protocol since it is an
Industry Standard in USA, Europe, and Asia.
5. Many manufacturers built dispatch consoles with this
capability.
6. 5-Tone offers flexible muting characteristics.

1. The PMR model and repeater functionality provides
the programmer with RX Text identifiers. When a
particular 5-Tone sequence is received, a repeater
with display will show the alias attributed to that tone
sequence.
2. This repeater also has variable audible signals and
beeps.
3. When transmitting a 5-Tone sequence, the repeater
can select from a programmed list with aliases in
order to identify the code desired for TX.
4. PMR repeaters allow for TX code editing and the
creation of a custom “User Code” that will allow the
programmer to create a unique code for a customer.
5. The system also allows for a user to select the TX
codes by assigning a button on the repeater.

3. “Answer Back Call” – Also known as “Radio Check”
allows the dispatch console to send a 5-Tone
sequence to a particular radio and when the target
radio receives the tone it answers back with another
tone. This function serves as a tool to verify if a unit
is “ON” and within range.
4. “Auto Transmit” – Also known as “Radio Spy” allows
the dispatcher to send a 5-Tone signal to the radio
causing it to open its transmitter microphone audio
(Hot Mic) in order to listen to whatever is happening
in the proximity of the radio. This is also very useful
in emergency cases where the user may not be able
to trigger the microphone.
5. “Stun/Kill – This function allows the dispatch
console to disable temporarily or permanently a unit
using the 5-Tone capabilities. When “Stun” is used,
the unit may regain its functionality by entering a
password. When Kill is used, the radio only regains
functionality by reprogramming the unit using the
cloning software.
6. 5-Tone allows the PTT ID functionality on the
repeater.
7. As with 2-Tone, PMR also provides audible alerts,
emergency signalling and Dispatch functionality
making it a workable upgrade to an existing fleet.
