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
CLR TX
.
The radio does not transmit until you set
the Secure/Clear switch to the clear
position.
If the “Ignore Secure/Clear Switch when
Strapped” programming option is enabled,
the radio transmits without displaying any
messages in the strapped mode of
operation, regardless of the Secure/Clear
switch setting. This option must be
preprogrammed by a qualified radio
technician.
The Secure/Clear switch only applies
when the radio is transmitting.
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
SEC TX
.
The radio does not transmit until you set
the Secure/ Clear switch to the secure
position.
You can request to configure the radio to
ignore the clear voice or insecured
transmission when the radio is in secured
transmission. Check with your agent for
details.
