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.
