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
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, you hear an invalid mode tone and the
display shows Clear TX only.
The radio will not transmit until you set the
Secure/Clear switch to the clear position.
Selecting Clear Transmissions
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, you hear an invalid mode tone and the
display shows Secure TX only.
The radio will not transmit until you set the
Secure/ Clear switch to the secure position.
The radio can be configured to ignore the clear
voice or insecured transmission when the radio is
in secured transmission. Check with your agent for
details.
