Note:

Before adjusting the squelch threshold to a different

setting, use the volume control

 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.
