Sennheiser EMP 2015 manual Selecting the content of the standard display

SqELCH	Adjusting the squelch threshold (receiver section only)
	The amplifier’s receiver section is equipped with an adjustable squelch which
	eliminates annoying noise when the transmitter is turned off. It also suppresses
	sudden noise when the transmitter leaves the reception area.
	￿ Press the SET button to select the “SqELCH” menu. “SqELCH” appears on
	the display; after a short pause the current squelch setting is indicated.
	￿ With the / buttons you can now select a different setting. The squelch
	can be turned off (0 dB) or adjusted in 5-dB steps from 5 dB to 40 dB.
	(Selecting a smaller value reduces the squelch threshold, selecting a higher
	value increases the squelch threshold.) The new setting starts flashing on
	the display. Set the squelch threshold – with the transmitter turned off –
	to the lowest possible value that suppresses hissing noise. With the squelch
	set to a high value, the receiver section will be less sensitive to interference
	but, on the other hand, the transmission range will be reduced.
	Note:
	If the receiver’s squelch is set to “0 dB” and you turn the transmitter off,
	hissing noise with high dynamics will occur.
	￿ Press the SET button to return to the top menu level. The display then
	switches back to the standard display.

DiSPL	Selecting the content of the standard display
	With both transmitter and receiver section you can choose the content of the
	standard display i.e. whether the frequency (in MHz) or the channel number
	is displayed.
	￿ Press the SET button twice to select the “DiSPL” menu. “DiSPL” appears
	on the display; after a short pause the current setting is indicated.
	￿ With the / buttons you can now choose between:
	Frequency:	“FrEqu”
	Channel number:	“ChAnnL”

The new setting for the standard display starts flashing on the display.

￿ Press the SET button to return to the top menu level. The display then switches to the new standard display.
