WARNING
Do not adjust a bit switch or use a setting that is described as “Not used”,
as this may cause the machine to malfunction or to operate in a manner
that is not accepted by local regulations. Such bits are for use only in other
areas, such as Japan.
NOTE:
Default settings for bit switches are not listed in this manual. Refer to the
System Parameter List printed by the machine.

Technical data printout on the
Journal
0: Disabled
1: Enabled
1: Instead of the personal name, the following
data are listed on the Journal for each G3
communication.
e.g. 0000 32V34 288/264 L0100 03 04
(1) (2)(3) (4) (5) (6) (7) (8)
(1): EQM value (Line quality data). A larger number means more errors.
(2): Symbol rate (V.34 only)
(3): Final modem type used
(4): Starting data rate (for example, 288 means 28.8 kbps)
(5): Final data rate
(6): Rx revel (refer to the note after this table for how to read the rx level)
(7): Total number of error lines that occurred during non-ECM reception.
(8): Total number of burst error lines that occurred during non-ECM reception.
Note:
EQM and rx level are fixed at “FFFF” in tx mode.
The seventh and eighth numbers are fixed at “00” for transmission records and
ECM reception records.

Rx level calculation
Example: 0000 32 V34 288/264 L 01 00
03 04
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 marks on received
pages
0: Disabled
1: Enabled
If this bit is 1, a mark will be printed on the left
edge of the page at any place where a line error
occurred in the data. A noisy line can cause such
errors.
