3.6. Transmitter Operation
The unit transmits on the active frequency (upper line) as
long as a PTT (press to talk) switch is pressed.
Transmission Reception
„TX“ indicates normal transmitter operation.
In the lower left corner of the display the carrier modulation is dynamically
displayed. It corresponds to the side tone which is not available on gliders
when no earphones are in use.
In order to avoid the blocking of the frequency by unintentional long
transmissions (stuck microphone) the transmitter is switched off after two
minutes and the display changes from „TX“ to „Te“. To resume
transmission the PPT switch first must be released and then be pressed
again.
