18 Adjusting the squelch
Your EK 3041-U receiver is equipped with an adjustable squelch control
which eliminates annoying noise when the transmitters are switched on and
off. It also suppresses sudden noise when a transmitter leaves the reception
area and there is no longer sufficient transmitter power received by the
receiver.
Ǡ Briefly press the SET button twice.
The display now indicates „Squelch“ in alternation with one of nine
possible squelch values (adjustable in 5-dB steps from „OFF“ to „40“).
These values are – to some extent – comparable to an input voltage in dB µV.
Ǡ With the ̆ / ̄ buttons you can now select a different setting. Selecting a
smaller value reduces the squelch threshold, selecting a higher value
increases the squelch threshold.
Ǡ The new setting becomes effective immediately without having to be
stored.
Notes
Ǡ You can discontinue the programming of this menu at any time. Press the
SET button to change to the next menu or briefly press the ON/OFF
switch to discontinue your entry. The cancellation is briefly confirmed on
the display with „ESC“. The display then switches back to the standard
display (display of receiving frequency or channel number)(u see
chapter 16).
Ǡ After about 15 seconds, the receiver automatically returns to normal
operation if no entry has been made during this period. Here, too, „ESC“
flashes briefly.
