Secure Operation
Secure operation provides the highest level of commercially
available voice security on trunked or conventional channels.
Unlike other forms of security, Motorola digital encryption
provides signalling that makes it virtually impossible for others to
decode any part of an encrypted message.
• Selecting Secure or Clear Transmissions
The Secure/Clear Switch (if programmed, see page 2)
will set the transmit operation of the radio before the
PTT Switch is pressed; the transmit operation cannot
be changed while the PTT Switch is pressed.
If a channel is programmed for
secure-only operation , and the
Secure/Clear Switch is in the
clear ( ) position, when the
PTT Switch is pressed, the
display will show “SECURE
TX ONLY,” an invalid-mode
tone will sound, and the radio
will not transmit until the
Secure/Clear Switch is set to
the secure ( ) position.
