Selecting the setting “SQ LO” reduces the squelch threshold,
selecting the setting “SQ 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 transmission
range will be reduced. Therefore, always adjust the squelch
threshold to the lowest possible setting.
y When in the setting mode of the “SQELCH” menu, pressing the
button for more than three seconds will switch the squelch
off. “SQ.OFF” flashes on the display. If no RF signal is being
received, hissing noise will occur. This setting is for test purpo-
ses only.
LTD Limiting the volume at the headphone output
Via the “LTD” menu, you can switch the limiter on and off. With the
limiter switched on, the maximum possible volume of the
headphone output will be reduced about approx. 15 dB.
Note:
The receiver is preset so that the limiter is switched on. We
recommend to keep the limiter switched on all the time.
