PTT ID
Each radio can be allocated with a 15 digit ID consisting of digits 0-9 or
A,B,C or D. The PTT ID recognition signal can be set per channel or the side
key can be programmed to activate / deactivate it. The radio can be
programmed to send the ID either at the beginning and/or end of a
transmission. The PTT ID or automatic number identification (ANI) is used to
connect with a repeater or telephone system, or for a control centre’s
communication management to identify this caller’s ID using other radios
equipped with a DTMF Decode function.
Begin of Tx:
The radio will send out the ID first before allowing voice
communication once the PTT key is pressed.
End of Tx:
The radio will send out the ID at the end of a communication once
the PTT key is released.
Both:
The radio will send out the ID first before and after the PTT key is
pressed.
Scramble
Scrambler can be set per channel or the side key can be programmed to
activate / deactivate it. Scrambling technology use a coded algorithm to
invert the audio signal and make it unintelligible unless the other radio also
has the same descramble function. This function is used to achieve extra
privacy on the same channel.
Compander
A compander can be set per channel or the side key can be programmed to
activate / deactivate it. The compander will make communication more clear
by improving the ‘Signal to Noise Ratio’ using compression and amplification
technology and decrease the noise when receiving a signal.
Power Selection (only in dealer license version)
Maximum communication range is achieved when the transceiver is set to
high power mode, whilst lower power settings will save battery life. The
power can be set on low (500mW) or High (4W).
