6.1 CD LOCKOUT
When CD Lockout is set ON the M760 will not
permit the PTT button to operate if a radio signal is
currently being received.
If the user attempts to transmit by pressing the PTT
button, the M760 will not transmit.
The signal being received will be heard in the
headphones or speaker.
When CD Lockout is set OFF the M760 will permit
the PTT to operate if a radio signal is currently being
received.
Background:
In high traffic areas such as circuit patterns, there is often a high level of radio traffic. There is also a high
instance of two aircraft trying to transmit at the same time. When this occurs the two transmissions interfere
with each other, and neither call can be properly received.
The CD Lockout is toggled by pressing the Toggle Switch. The factory default is to have the CD
lockout OFF.
