Secure Operations
Secure radio operation provides the highest commercially
available level of voice security on both trunked and
conventional channels.
Unlike other forms of security, Motorola digital encryption
provides signaling that makes it virtually impossible for others to
decode any part of an encrypted message.
Selecting Secure Transmissions
Procedure:
Turn the preprogrammed Secure/Clear switch to the secure
position.
Note: If the selected channel is preprogrammed for clear-only
operation – when you press the PTT button, an invalid
mode tone sounds and the display shows CLR TX.
The radio will not transmit until you set the Secure/
Clear switch to the clear position.
Selecting Clear Transmissions
Procedure:
Turn the preprogrammed Secure/Clear switch to the clear
position.
Note: If the selected channel is preprogrammed for secure-
only operation – when you press the PTT button, an
invalid mode tone sounds and the display shows SEC
TX.
The radio will not transmit until you set the Secure/
Clear switch to the secure position.
