SW4 No. 7, No. 6 Number of CNG detect (STAND-BY mode)
Used for detection of CNG in 1 to 4 pulses.
SW5 No. 1 Dats format
Used to select date display/print formats.
SW5 No. 2 Time format
When this switch is set to “O”, time is displayed in 12-hour system.
When set to “1”,24-hour system.
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 applide.
SW5 No. 4 Footer print
When set to “l”, 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 Substituts reception
Selection of substitute reception in the case of recording paper exhausted
or paper jam. If set to “ND”, 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 Subsfifufe 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. 6 CSI transmission
CSI signal contains the sender’s phone number registered in the ma-
chine. If this switch is set to “l”, no sender’s name will be printed at the
receiving side.
SW6 No. 1 H2 mode
Used to determine H2 mode (15 set transmission mode). When set to
OFF, H2 mode is inhibited even though the transmitting machine has
H2 mode.
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. 6 Modem speed (DCS data reception speed)
Used to determine the initial modem speed. The default is 144OOBPS
(V17). It may be necessary to program it to a slower speed when fre-
quent 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 63 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 usefull for overseas communication to avoid an echo suppres-
sion problem, if set to 1.
SW7 No. 4 Non modulated carrier in V29 transmission
Though transmission of a non-modulated carrier is not required fortrans-
mission by the V29 modem according to the CCllT Recommendation,
it may be permitted to send a non-modulated carrier before the image
signal to avoid an echo suppression problem.
It may be usefull for overseas communication to avoid an echo suppres-
sion problem, if set to 1.
SW7 No. 5 EOL defect timer
Used to make a choice of whether to use the 25second or 13-second
timer for detection of End of line.
This is effective to override communication failures with some facsimile
models that have longer End of line detection.
SW7 No. 6, No. 7 Reserved
Set to “0”. L’rJE + PPcriOCOl )u1oh1l~cXz (I) onl
SW7 No. 6 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 1
meter for copy or transmit, and 1.5 meters for receive.
It is possible to set it to “No limit“ to transmit a long document, such as
a computer print form, etc. (In this case, the receiver must also be set to
no limit.)
SW6 No. 1 , No. 2 Digital line equalization setting (Reception)
Needs to be set to the line characteristics. A guide line is the distance
between the exchange office and the telephone terminal. Since it needs
not to be set in the normal case since it has been set to 1.6Km, it should
be corrected in case communication failures occur frequently.
SW6 No. 3 Dialing pausing (se&pause)
Pauses can be inserted between telephone numbers of direct dial con-
nection. Selection of 4 set or 2 set pause is available.
SW6 No. 4 - No. 6 Signal transmission level
Used to control the signal transmission level in the range of-OdB to-
31dB. The factory setting is at-10dB (MODEM output).
SW9 No. 1, No. 2 CED tone signal interval
For international communication, the 2100Hz CED tone may act as an
echo suppression switch, causing a communication problem.
Though SW9 No.1 , No.2 are normally set to 0, it should be changed this
time between the CED tone signal to eliminate the communication prob-
lem 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 unfavorable state
and picture cannnot be received.Usually, the control is executed accord-
ing 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. 6 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 Resenred
Set to “0”.
