If the error frame often occurs because of the
symbol rate is too high, setting this switch to "1"
mask that symbol rate and keep down the
occurrence of error frame.

Adjust
SNR means that Signal Noise Ratio. If the SNR is
less than the threshold you set, the data pump
overrides the bandwidth evaluation algorithm and
forced the symbol rate to 2400 baud.
