Secure Features
Transmitting in Secure and Clear Modes
If your radio is secure-capable, you can transmit messages in secure
mode.
To transmit a message in secure or encrypted mode:
1 Press and release the preprogrammed
SEC
softkey when your
radio is on personalities or talkgroups that have been designated
by your system manager for secure transmissions.
2 Press the PTT button to transmit while the radio is on a
personality or talkgroup programmed for secure.
The radio will begin transmitting in secure mode. The display
shows
D
(secure status annunciator) when the transmission is in
progress.
To transmit a message in non-encrypted or clear mode:
Press and release the preprogrammed
SEC
softkey again.
The radio will transmit in clear mode when you press the PTT
button. The display does not show the
D
status annunciator.
Note: You cannot change from secure to clear while the PTT button
is pressed. The radio will generate an illegal tone and the
transmission will be ended.
Take note that the radio will then exit from its current mode. If
current mode is SECURE, then it will exit to CLEAR mode.
Secure-equipped radios automatically determine whether a voice
message is being received in secure or clear mode. This allows you
to receive either type of message without having to reset the
preprogrammed Secure button.
