SW-A6 No. 2 End buzzer
Setting this bit to 0 will disable the end buzzer (including the error
buzzer/on-hook buzzer).
SW-A6 No. 3 Disconnect the line when DIS is received in RX
mode
Bit1= 0: When DIS signal is received during RX mode, the line is
disconnected immediately.
Bit1= 1: When DIS signal is received during RX mode, the line is
disconnected on the next tone.
SW-A6 No. 4 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.

be assumed.
SW-B1 No. 5 ~ No. 8 Recall times
Choice is made as to how many redials should be.
SW-B2 No. 1 Dialing pause (sec/pause)
Pauses can be inserted between telephone numbers of direct dial
connection. Selection of 4 sec or 2 sec pause is available.

SW-B4 No. 6 ~ No. 8 Reserved
Set to "0".
SW-B5 No. 1 ~ No. 5 DTMF signal transmission level (Low)
The transmission level of DTMF signal is adjusted. (lower frequency)
00000: 0dBm
↓
11111: -15.5dBm (-0.5dBm x 31)
SW-B5 No. 6 ~ No. 8 Reserved
Set to "0".
SW-B6 No. 1 ~ No. 5 DTMF signal transmission level (High)
The transmission level of DTMF signal is adjusted. (higher frequency)
00000: 0dBm
↓
11111: -15.5 dBm (-0.5dBm x 31)
SW-B6 No. 6 ~ No. 8 Reserved
Set to "0".
SW-C1 No. 1, No. 2 Reading slice (Binary)
Used to determine the set value of reading density in standard/fine
mode. The standard setting is "00" (Factory setting is "00")
SW-C1 No. 3, No. 4 Reading slice (Half tone)
Used to determine the set value of reading density in half tone mode.
The standard setting is "00" (Factory setting is "00")
SW-C1 No. 5 Line density selection
Used to set the transmission mode which is automatically selected
when the Resolution key is not pressed. In the copy mode, however,
the fine mode is automatically selected unless the Resolution key is
manually set to another mode.
SW-C1 No. 6 ~ No. 8 Reserved
Set to "0".
SW-D1 No. 1 ~ No. 4 Number of rings for auto receive
When the machine is set in the auto receive mode, the number of
rings before answering can be selected. It may be set from one to
four rings using a binary number. Since the facsimile telephone could
be used as an ordinary telephone if the handset is taken off the hook,
it should be programmed to the user's choice. If the soft switch was
set to 1, direct connection is made to the facsimile. If a facsimile
calling beep was heard when the handset is taken off the hook, press
the START key and put the handset on the hook to have the facsimile
start receiving. If it was set to 0 accidentally, receive ring is set to 1.
NOTE: If the machine is set to answer after a large number of rings, it
may not be able to receive faxes successfully. If you have
difficulty receiving faxes, reduce the number of rings to a max-
imum of 6.
SW-D1 No. 5 Automatic switching manual to auto receive mode
This soft switch is used to select whether the machine should switch
to the auto receive mode after 5 rings in the manual receive mode or
remain in the same way as SW-D1 No. 1, No. 2, No. 3 and No. 4
"0"1"0"1"(5 rings).
SW-D1 No. 6 ~ No. 8 Reserved
