CP30 INSTRUCTION MANUAL
Voice Scrambler
Your CP30 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.
To Enable or Disable the Scrambler:
1. Hold the

Narrow Band Filter
The CP30 receiver is tted with a user-selectable bandwidth lter that allows
the receiver to be adjusted for either wide or narrow band reception on channels
1-40. This feature provides additional compatibility with older 40-channel radios.
Switching the lter O increases the tolerance of the CP30 receiver to older
wideband 40 channel radios or to signals that might be slightly o frequency.
Switching the lter On increases the selectivity of the receiver on channels 1-40
which can help reduce interference from strong interfering signals on adjacent
channels.
