SIG DET S LEVEL
SIG DET S LEVEL judges whether the DSC frequency to use to send a DSC message is in
use or not. The DSC message is not transmitted when the signal strength on the DSC
frequency is higher than that set here. When the DSC frequency becomes clear, the DSC
message is automatically transmitted. The setting range is OFF –255 and the default setting
is 100.
1. Rotate the [ENTER] knob to select "SIG DET S LEVEL".
2. Press the [ENTER] knob to display the S LEVEL pop-up window.
3. Rotate the [ENTER] knob to adjust the indicator bar. Too low a setting stops
transmission of a DSC message because it detects noise on the DSC frequency.
Alternately, too high a setting transmits the DSC message though low signal level is
present on the DSC frequency used.
4. Press the [ENTER] knob to finish.
