Enabling Secure Transmission
168
Secure radio operation provides the highest commercially available level of voice security on both trunked and
conventional channels.
By default, the radio automatically enters the encrypted environment without having to manually select or clear
the secure transmission.
This extended feature can only be enabled through CPS configuration.
Procedure:
1. From the home screen, scroll left or right to Sec.
2. Press the Menu Select button directly below Sec.
The display shows the Secure Operation icon and the current key if multi-key has been enabled.
3. Monitor the mode to be sure it is not in use.
4. Press PTT button to transmit.
Note: If the selected channel is preprogrammed for clear only operation ā when you press the PTT button, an
invalid mode tone sounds and the display shows Clear TX only. The radio does not transmit until you disable
the secure mode.
The radio can be configured to ignore the clear voice or unsecured transmission when the radio is in secured
transmission
