Selecting Clear Transmissions

Turn the preprogrammed Secure/Clear switch to the
clear position.
• 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 Secure TX only.
• 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.
• 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.
