Adjusting the squelch level

The squelch of a two way radio shall suppress undesired noise on channels or frequencies where
just no receiver signal is present. As soon as a signal will be received, the squelch opens and the
loudspeaker will reproduce the audio signal. The squelch can be adjusted from very sensitive (or
even open) to more tight levels, where the radio has a certain immunity against interference or far
away signals. You can select the squelch setting as you did it with the volume.
Press the combined VOL-SQ button twice. Now you have 10 seconds time to select the desired
squelch level by means of the UP-DOWN keys.
You can see in the display the bar graph in the lowest line showing the selected volume steps:
Please note that in the maximum sensitive position the squelch can remain open. This position can
be used in cases, where the received signal should be very weak.
But the correct position of the squelch level is important during scanning, because an open squelch
means automatically a scan or search stop. So you should decide which is the best setting
dependent on your present local position.
The best setting can also change with your antenna environment. If you are in an area with strong
interference signals, it may be necessary to keep the squelch more closed than in a rural area far
away from transmitting stations.
Short introduction into "Searching Frequencies" and "Scanning Channels"
The first thing you do with the scanner during first time use is to search for busy frequencies in the
selected band(s).
If you are in Germany, you may note that the scanner offers you a special German pre-
programmed band plan setting for German networks. The reason is that in Germany some radio
services use different channel spacing and frequency offsets compared to other countries. Our
unique pre-programmed search bands make it very easy to find the transmissions there, because
the scanner starts immediately with the correct settings.

Searching frequencies

Searching means simply checking a certain band or frequency range for transmissions. If you do
not know where to find stations, just start at one band and continue the search.

Scanning channels

Scanner specialists talk about scanning, if you let the scanner only check previously stored
frequencies for activity.
Stored frequencies are called "channels".
