R
Setting microphone sensitivity on transmitter SK 2013 PLL
The microphone sensitivity should be set high enough on the regulator (R) that, on the one hand, the green LED on the Receiver EK 2013 PLL does not go out during normal speaking and, on the other hand, low enough that normal surrounding noise does not activate the LED display.
The optimum setting is usually between 5 and 7.
