During the soundcheck, the receiver records the RF level and the AF level. The recording result is displayed on the “Soundcheck” standard display:

AF Max	Max. audio level	￿ On your transmitter, adjust the

	Adjustment range: 5 to 25 dBμV, adjustable in 2-dB steps, can be switched off
	The squelch eliminates annoying noise when the transmitter is switched off or when there is
	no longer sufficient transmitter power received by the receiver.
CAUTION!	Danger of hearing damage and material damage!
	If you switch the squelch off or adjust the squelch threshold to a very low value, loud hissing
	noise can occur in the receiver. The hissing noise can be loud enough to cause hearing damage
	or overload the loudspeakers of your system!

￿Always make sure that the squelch is switched on.

￿Before adjusting the squelch threshold, set the volume of the headphone output (see page 14) and the audio output level to the minimum (“AF Out”, see page 25).

￿Never change the squelch threshold during a live transmission.

￿Adjust the squelch threshold – with the transmitter switched off – to the lowest possible setting that suppresses hissing noise.

If you adjust the squelch threshold to a high value, the transmission range will be reduced under adverse RF reception conditions.
