5.3 Basic OperaƟon
5.3.6 Funcon screen - Seng squelch level
The TR-910 has a S/N squelch which automacally adapts itself to the background noise, so normally there will
be no need for adjustment during normal operaon. The value is in dB S/N and the default value is 12 dB. The
value can be adjusted between 5 dB and 20 dB. Low values will increase the risk for false squelch li which can
be annoying. In most cases the default value of 12 dB will be the best choice.
