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
yMID = middle
y HI = high
CAUTION!
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.
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:
yIf 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.
