Note:
Before adjusting the squelch threshold to a different
setting, use the volume control
Ƹ to set the volume for the
connected headphones to the minimum.
There are three possible squelch setting:
y LO = low
y MID = middle
y HI = high
Selecting the setting “LO” reduces the squelch threshold,
selecting the setting “HI” increases the squelch threshold.
Adjust the squelch threshold – with the transmitter switched
off – to the lowest possible setting that suppresses hissing
noise.
Important note:
y If the squelch threshold is adjusted too high, the trans-
mission range will be reduced. Therefore, always adjust
the squelch threshold to the lowest possible setting.
High volume levels can damage your hearing!
When in the setting mode of the “SQELCH”
menu, pressing the
̄ button for more than
three seconds will switch off the squelch.
“SQ.OFF” appears on the display. If no RF signal
is being received, hissing noise will occur.
̈ This setting is for test purposes only and
must only be used by service technicians.
