Detailed Discussions of Bit 0
Select whether to make the TCF criteria loose when the system with a V.34 modem receives
an image using the V.17 protocol.
When "Loose" is selected, fallback hardly occurs when an image is received using the V.17
protocol.
However, since the transmission speed is fast, erroneous lines can be generated after start
of image reception or the communication time can become long due to retransmission of
erroneous frames.
Detailed Discussions of Bit 1
Selects whether or not the echo protect tone is transmitted for high-speed transmission
(9600 or 7200 bps).
If errors due to line conditions occur frequently during fax transmission, select “Transmitted”.
When “Transmitted” is selected, a non-modulated carrier is transmitted as a synchronization
signal before the image transmission.
MEMO:
Codes for errors that can occur during transmission because of line conditions:
##100, ##104, ##281, ##282, ##283, ##750, ##755, ##760,##765
Detailed Discussions of Bit 7
Use it to enable/disable transmission of a 1080-Hz tonal signal before transmission of the
CED signal.
Select 'transmit' if errors occur frequently because of an echo when reception is from
overseas.

1 Check CI frequency Yes No
2 the number of final flag sequences of protocol signals 2 1
3 Reception mode after CFR signal transmission high speed high speed/low

Detailed Discussions of Bit 1
In automatic recieving, CI frequency check can be selected. If ‘Yes’ is selected, the upper and
lower limits of the CI frequency are checked, and automatic recieving can only go ahead if
both values meet German regulations.
Detailed Discussions of Bit 2
Use it to select the number of last flag sequences for a protocol signal (transmission speed at
300 bps). Select '2' if the other party fails to receive the protocol signal properly.
MEMO:
Any of the following error codes may be indicated at time of transmission
##0100, ##0280, ##0281, ##0750, ##0753, ##0754, ##0755, ##0758, ##0759, ##0760,

Detailed Discussions of Bit 3
Use it to select an appropriate reception mode after transmission of the CFR signal.
If errors occur frequently at time of reception because of the condition of the line, select 'high
speed' for reception mode and, at the same time, selects 'do not receive' for 'ECM reception.'
