The four-digit hexadecimal value (N) after "L" indicates the RX level.
The high byte is given first, followed by the low byte. Divide the decimal value of N by -16 to get the RX level.
In the above example, the decimal value of N (= 0100 [H]) is 256.
So, the actual RX level is 256/-16 = -16 dB

Line error mark print
0: OFF, 1: ON (print)
When "1" is selected, a line error mark is printed on the printout if a line error
occurs during reception. This shows error locations when ECM is turned off.
5
G3 communication parameter
display
0: Disabled
1: Enabled
This is a fault-finding aid. The LCD shows the key parameters (see "G3
Communication Parameters" below this table). This is normally disabled
because it cancels the CSI display for the user.
Be sure to reset this bit to "0" after testing.
6
Protocol dump list output after
each communication
0: Off
1: On
This is only used for communication troubleshooting. It shows the content of
the transmitted facsimile protocol signals. Always reset this bit to 0 after
finishing testing.
If system switch 09 bit 6 is at "1", the list is only printed if there was an error
during the communication.
