Adjust
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.
See above (switch 5 to 2).
Adjust
SNR means that Signal Noise Ratio.
If the SNR is less than the threshold you set, the
modem overrides the bandwidth evaluation
algorithm and forces the symbol rate to2400 baud.
