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.
Error Code:
Any of the following error codes may be indicated at time of transmission
##100, ##280, ##281, ##750, ##753, ##754, ##755, ##758, ##759, ##760, ##763 ##764,
##765, ##768, ##769,##770, ##773, ##775, ##778, ##780, ##783, ##785, ##788
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.'
Error Code:
Any of the following error codes may be indicated at time of reception because of line condition
##107, ##114, ##201
MEMO:
Be sure to change bit 4 before changing this bit; if errors still occur, change this bit.
When 'high speed' is selected, only high-speed signals (images) will be received after
transmission of the CFR signal.
T-5-5
Detailed Discussions of Bit 4
Use it to select the time length during which low-speed signals are ignored after transmission
of the CFR signal.
If the condition of the line is not good and, therefore, the reception of image signals is difficult,
select '1500 ms.'
