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 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.
