1. Although it is dubbed as 5-Tone, this signalling
protocol consists of a fast data burst of one (1) to
seven (7) frequency tones that can selectively signal
a radio.
2. Originally a European signalling protocol, 5-Tone has
numerous formats such as:
a. CCIR
b. ZVEI1
c. ZVEI2

1. Unlike 2-Tone, where the programmer must know the
frequency to be used on each tone, 5-Tone does not
require knowledge of the frequencies to be used.
2. Each digit in the sequence is already predefined with
a specific frequency depending on the format
selected in the Tone form section of the
programming.
3. All the programmer needs to know is what format is
being used and what code needs to do what. The

commercial radios.

1. Enable the repeater in PMR mode by selecting the
PMR Model in the Model section of the cloning
software.
2. To create the 5-Tone TX list, click on the 5-Tone
folder and select the “TX Code CH” icon.
3. In this section the user can create up to 32 encode
able tone sequences.
4. Each of these tone sequences can be identified with
an alias on the list.
being used and what code needs to do what. The
system does the rest.
If there was a need, although it is not highly
recommended, the tone formats can be modified to
specific needs.
4. The 5-Tone Format section of programming allows
the programmer to view and modify three (3) aspects
of the 5-Tone format.
•
Tone Period - is the length of the encoded tone.
•
Notone Timer – is the space required between
tones for proper decoding (tone spread).
•
Tone Length – is the time the radio takes to
decode a tone.
