SW5 No. 2 Date format
Used to select date display/print formats.
0: DAY-Month-Year
1: Month-DAY-Year
SW5 No. 3 Sender's information transmit
When it is set at 0, sender's name, sending page number and so on
are automatically printed in the recording paper on the receiving side
during transmission. Thus, the sender can be known on the receiving
side.
0: Applied
1: Not applied
SW5 No. 4 Footer print
When set to "1", the date of reception, the sender machine No., and the
page No. are automatically recorded at the end of reception.
SW5 No. 5 Reserved
Set to "0".
SW5 No. 6 Substitute reception
Selection of substitute reception in the case of recording paper ex-
hausted or paper jam. If set to "NO", auto receive is disabled even when
the receive memory is ready to receive.
Substitute reception is not performed even during receive operation.
SW5 No. 7 Substitute reception conditions
Selection of substitute reception according to existence of TEL number
from transmitting side. Initial setting allows substitute reception without
CSI. If set to "no", the receiver cannot receive any documents
SW5 No. 8 CSI transmission
CSI signal contains the sender's phone number registered in the ma-
chine. If this switch is set to "1", no sender's name will be printed at the
receiving side.
SW6 No. 1 H2 mode
Used to determine reception of H2 mode (15 sec transmission mode).
When set to OFF, H2 mode reception is inhibited even though the trans-
mitting machine has H2 mode function.
SW6 No. 2 MH fixed
Normally set to allow automatic selection of MH and MR mode accord-
ing to the remote side.
If set to 1, the mode is fixed to MH and is useful if the remote side is a
MH only unit ; or a lot of image distortion is met due to a bad line.
SW6 No. 3, No. 4 Reserved
Set to "0".
SW6 No. 5 ~ No. 8 Modem speed (DCS data reception speed)
Used to determine the initial modem speed. The default is
14400BPS(V.17). It may be necessary to program it to a slower speed
when frequent line fallback is encountered, in order to save the time
required for the fallback procedure.
SW7 No. 1, No. 2 Reception speed fixed
The transferable speed of modem in the receiving mode is set.
SW7 No. 3 DIS receive acknowledgement during G3 transmission
Used to make a choice of whether reception of NSF (DIS) is acknowl-
edged after receiving two NSFs (DISs) or receiving one NSF (two DISs).
It may be useful for overseas communication to avoid an echo sup-
pression problem, if set to 1.
SW7 No. 4 Non modulated carrier for V.29 transmission mode
Though transmission of a non-modulated carrier is not required for trans-
mission by the V29 modem according to the CCITT Recommendation,
it may be permitted to send a non-modulated carrier before the image
signal to avoid an echo suppression problem.
It may be useful for overseas communication to avoid an echo sup-
pression problem, if set to 1.
SW7 No. 5 EOL detect timer
25 seconds or 13 seconds are selected for the detection timer of EOL
(end of line). This is effective against communication trouble on a spe-
cific type of long EOL.
0: 13 seconds
1: 25 seconds
SW7 No. 6 Protocol monitor
Normally set to "0". If set to "1", communication can be checked, in case
of troubles, without using a G3 tester or other tools.
When communication FSK data transmission or reception is made, the
data is taken into buffer. When communication is finished, the data
analyzed and printed out. When data is received with the line monitor
(SW7-No.7) set to "1" the reception level is also printed out.
SW7 No. 7 Line monitor
Normally set to "0". If set to "1", the transmission speed and the recep-
tion level are displayed on the LCD. Used for line tests.
SW7 No. 8 Length limitation of copy/send/receive
Used to set the maximum page length.
To avoid possible paper jam, the page length is normally limited to 1m
for copy or transmit, and 1.5 meters for receive.
It is possible to set it to "No limit" to transmit/receive a long document,
such as a computer print form, etc. (In this case, the receiver/transmit-
ter must also be set to no limit.)
SW8 No. 1, No. 2 Digital line equalization setting (Reception)
The specific line equalizer is inserted.
No. 1 No. 2
0 0 The line equalizer built in the modem is turned off.
0 1 Line equalizer corresponding to 1.8 km
1 0 Line equalizer corresponding to 3.6 km
0 1 Line equalizer corresponding to 7.2 km
SW8 No. 3 Dial pausing (sec/pause)
Pauses can be inserted between telephone numbers of direct dial con-
nection. Selection of 4 sec or 2 sec pause is available.
SW8 No. 4 ~ No. 8 Signal transmission level
Used to control the signal transmission level in the range of –0dB to
–31dB.
SW9 No. 1, No. 2 CED tone signal interval
For international communication, the 2100Hz CED tone may act as an
echo suppresser switch, causing a communication problem. Though this
soft switch is normally set to "00", it should be change the time between
CED tone and DIS signal from 75ms to 1000ms to eliminate the commu-
nication problem caused by echo.
SW9 No. 3 Equalizer freeze control (MODEM)
This switch is used to perform reception operation by fixing the equal-
izer control of modem for the line which is always in an unfavorable
state and picture cannot be received. Usually, the control is executed
according to the state of line where the equalizer setting is changed
always.
SW9 No. 4 Equalizer freeze conditions
Setting which specifies SW9 No.3 control only in condition of 7200bps
modem speed.
SW9 No. 5 CED detection time
The detection time of the CED signal from the called side in the auto
calling mode is set.
SW9 No. 6, No. 7 Reserved
Set to "0".
SW9 No. 8 Busy tone detection (after auto dial)
this is used to set busy tone detection in auto dialing.
SW10 No.1, No. 2 Reserved
Set to "0".
