FF
This function enables transmitted voice to be scrambled, to prevent radios without a
scrambler from listening in on the conversation.
This low security form of encryption is sufficient to make speech unintelligible to other casual
listeners, however it does not offer high level security as other radios programmed with a
scrambler function will be able to unscramble it.
Speaker sounds a 'bip-bip' tone when PTT is pressed to indicate that scrambler is active.
Scrambler On/Off state is reset to Off at power-up.
Only normal voice calls are scrambled in trunk mode.
