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.
