Ricoh IM C300 Service Manual page 1529

Example:
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

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.
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.
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.
Do not change the setting.
