Q
UESTION
When connecting the
CT-96
headset cable between
the radio and a headset, the red transmit LED on
the radio turns on and the radio cannot be operated.
Can I purchase the optional PTT Switch from Ver-
tex Standard?
Will my headset work with this radio?

This happens when the connector on the
CT-96
headset cable is simply
pushed into the
MIC/EAR
jack.
The jack must be screwed into the
MIC/EAR
jack to make proper contacts
within the radio.
Contact your Aviation dealer for details on purchasing an aftermarket Push-
To-Talk switch.
The
CT-96
headset cable is made to operate with most headsets; however
to be concretely sure check with the headset manufacturer providing the
wiring shown below. Please confirm the connections and connector sizes
are correct.
