HT98R068-1 Two-way Radio OTP MCU
Audio – Scrambler/De-scrambler Function Setting
Scrambling implements reversion signal processing which is an encryption method for
the transmitted signals. In the TX mode, signals transmitted through a scrambler will
become meaningless and impossible to use. Likewise, when in the RX mode, after the
descrambler is used, the scrambled signals will be returned back to their original signals.
The device provides eight reversion frequencies selection (CLI CMD-013A, 013B).
Disable the scrambler before changing the frequency setting, and set the reversion
frequency to be changed, enable the scrambler function to complete the frequency
change. This function is controlled by the I/O CMD-2Ch [7] bit by using the following
setup.
