FUNCTION SETTINGS COMMENTS
0 Reconstruction time for
the first line 0: 6 seconds
1: 10 seconds When the sending terminal is controlled by a
computer, there may be a delay in receiving page
data after the local machine accepts set-up data and
sends CFR. If this occurs, set this bit to 1 to give the
sending machine more time to send data.
1 Substitute reception file
forwarding (FAX240 only) 0: Normal operation
1: Forward all files Set this bit to 1 if the printer is out of order.
The machine will forward all files to the Forwarding
terminal.

(FAX240 only) 0: Enabled
1: Disabled Set this bit to 1 when you want to switch off ECM.
3 PSTN/PBX dial tone and
busy tone detection 0: Enabled
1: Disabled Set this bit to 1 when you wish to disable tone
detection.
4 Closed network in
reception 0: Disabled
1: Enabled Set these bits to 1 to switch on Closed Network.
With Closed Network, communication will not go
ahead if the ID code of the other terminal does not
match the ID code of this terminal.
The ID code has to be programmed with function 16
before switching on these bits.
This feature may not be reliable when
communicating with another maker’s machine.

transmission 0: Disabled
1: Enabled
6 Remote read/write request 0: Always enabled

parameter display and
line monitoring after
handshaking 0: Disabled
1: Enabled This is a fault-finding aid. If this bit is set to 1, the
LCD shows the key parameters (see below) and the
speaker is enabled during message transmission and
reception.
This should be normally disabled because it cancels
the CSI/TSI (RTI) display for the user.
