frequency point, and click “Begin”, the programming software
will adjust the value automatically. When the value keeps stable,
click “OK”, the adjustment is completed.
c. In the “Tuning Mode” (input RF signal with the same
frequency as the adjusted frequency point and with the signal
level of -80dBm, audio frequency of 1kHz, and deviation of
3kHz to the antenna connector of the mobile radio), double click
“RSSI Level4”, and select “Wideband”. Choose a frequency
point, and click “Begin”, the programming software will adjust
the value automatically. When the value keeps stable, click “OK”,
the adjustment of that frequency point is completed. Use the
method to adjust the five frequency points of “Lowest”, “Low”,
“Mid”, “High” and “Highest” respectively.
d. In the “Tuning Mode” (input RF signal with the same
frequency as the adjusted frequency point and with the signal
level of -80dBm, audio frequency of 1kHz, and deviation of
1.5kHz to the antenna connector of the mobile radio), double
click “RSSI Level4”, and select “Narrowband”. Choose a
frequency point, and click “Begin”, the programming software
