"FSSI" is indicator of feedback signal strength and its range is from 0% to 100%.
At +5 dB level, FSSI=100%.
At -5 dB level, FSSI=75%
At -15 dB level, FSSI=50%
At -20 dB level, FSSI= 25%
*The readings listed above are typical values. There may be variations on different frequencies or
different units. Overall the recommended level of feedback signal is -15 dBm to -5 dBm.
When FSSI is less than 20% or higher than 75%, the reading will keep flashing, indicating the
feedback level may need to be adjusted.
