Adjusting the squelch threshold
Both receivers are equipped with a squelch that can be adjusted via the “Squelch” menu. The squelch eliminates annoying noise when the transmitter is switched off. It also suppresses sudden noise when there is no longer sufficient transmitter power received by the receiver.
The squelch can be adjusted in 13 steps from 0 to 30 μV. Selecting a smaller value reduces the squelch threshold, selecting a higher value increases the squelch threshold. Adjust the squelch threshold – with the transmitter switched off – to the lowest possible value that suppresses hissing noise.
Notes:
–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.
–If you adjust the squelch threshold to “0”, the squelch is switched off. If no RF signal is being received, hissing noise will occur. This setting is for test purposes only.
To adjust the squelch threshold:
Before adjusting the squelch threshold to a different setting, set the volume on a connected amplifier to the minimum.
Change to the setting mode of the “Squelch” menu. The current setting starts flashing.
Change the squelch threshold by turning the jog dial 7. The new setting becomes effective immediately.
After you have adjusted the desired squelch threshold, press the save button 8.
The squelch threshold is stored. The display changes to the selection mode of the operating menu.
Switching the booster supply voltage on/off
If you connect antenna boosters (e.g. AB 3700) or active antennas (e.g.
A3700, AD 3700), select “Booster Feed On” in the “Booster” menu so that the LEDs N and S light up; if you do not connect antenna boosters or
active antennas, select “Booster Feed Off” in the “Booster” menu so that the LEDs N and S do not light up.
Notes:
–The booster supply voltage is
–If you connect active antennas or antenna boosters, the current consumption of the overall device is increased.
–If the booster supply voltage is switched on, it remains switched on even when the receiver is switched off or muted.
Change to the setting mode of the “Booster” menu. The current setting starts flashing.
