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
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 (1W) or High (5W).
SK2 is Factory programmed on Power selection (long press).
Busy Channel lock out
The transceiver can be programmed with channel lock-out. When set,
this function will disable the PTT button from transmitting if there is any
activity on the same frequency with a different QT/DQT tone. This
prevents interference in community repeater systems.
Factory programmed on BCLO off
