HELP
Refer to your Radio Service Manual for the RSSI Alignment procedure. This
alignment procedure tunes the Received Signal Strength Indication
(that is, strength of the RSSI value for the current signal) for RSSI rated
audio power across the radio. It should be performed at -100dbm 3kHz

radio or system performance.
1. Press F4 to read the RSSI value. Repeat this step three times to
obtain an accurate reading.
2. Program the radio with the new RSSI value by pressing F8.
Reads the Received Signal Strength Indication (that is, the strength of
the RSSI value for the current signal).
Program the selected value into the radio.
Refers to the strength of the RSSI value for the current signal. In the
RSSI sampling scheme, RSSI values are separated into four levels: poor,
acceptable, good and excellent. The value in this field specifies the
poor/acceptable boundary and may range between 0 and 127.
The default is 0 (zero).
This is the softpot value for this frequency. The status bar shows the
relationship between this setting and the minimum and maximum
settings.
Use UP/DOWN Arrows To Adjust Softpot.
