VOICE SCRAMBLER
Your TX6600PRO incorporates a simple voice scrambler using band inversion
technology. The scrambler is compatible with other GME radios and with most
scramblers used by other manufacturers, allowing you to enjoy scrambled
communications with owners of both GME and non-GME radios.
Once the scrambler has been activated your transmission and reception will only
be intelligible to others using the same scrambler technology. When enabled the
scrambler is activated across all channels and must be deactivated to return to
normal voice operation.
Note: The ACMA does not allow scrambling on the emergency (5 and 35),
calling (11) or repeater input (30-38, 70-78) channels. Communications will not
be scrambled on these channels or while duplex mode is activated even if the
scrambler function is enabled.
