Manual Adjustable Squelch And Auto-Squelch Asq; Am / Fm Mode Switch; Special Interest Channels - Albrecht ae 5290 xls Anleitung

Particularly in FM, noise can be a nuisance on a free channel. With the adjustable muting
control (SQUELCH) You can suppress this noise - but also signals which are too weak to be
received properly.
This is how to adjust the signal strength required to switch on the loudspeaker, using the
SQUELCH control knob:
The further the control knob is turned to the right, the stronger a signal has to be in order to
be audible through the loudspeaker.
In order to adjust the set to be the most sensitive to incoming signals, switch to a free
channel:
• Use the rotary switch or the microphone buttons to find a free channel, where no
signal is displayed.
• Then turn the SQUELCH control carefully to the right until the noise just about
disappears.
ASQ – Automatic Squelch: You can obtain the most sensitive signal reception as well by
using the ASQ automatic squelch system. Simply turn the Squelch knob fully counter
clockwise, until it "clicks" . The system now detects automatically the noise on the channel
and opens the speaker when finding a reasonable receiving signal. The effect is similar as if
You would always re-adjust the manual squelch to the most sensitive trigger level.
Now the loudspeaker stays off when on a free channel but it switches back on when
receiving even very faint signals.
The muting adjustment is particularly important during channel
scanning. In this mode the point to which the set is adjusted decides
whether scanning is stopped at the signal or not. Therefore you should
test the various muting settings for various signal strengths and get to
know this function.
In the two programming modes 40/40 and 80/40, FM modulation is available on all channels,
but AM transmitting only on the 40 international channels. On these channels you can switch
between AM and FM using the function button AM / FM. The display shows either AM or FM
accordingly.
When you switch on the set the first time it operates on FM.
Please note that in 80/40 mode, on channels 41-80 it is possible to receive in AM, but
transmitting in AM is not possible (forbidden). If your radio is set to AM and you choose a
channel between 41 and 80, the radio will show Er (error) if you press PTT and try to
transmit.
The AM-FM switch has no function in 40 FM position of country switch or in a restricted FM
version for Austria or in FM only mode.
