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:
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. 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 purposes only.

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.
