dialing and dialing is unsuccessful, machine will try to recall only one
time.
SW-B5 No. 6 ~ No. 8 Reserved
Set to "0".
SW-B6 No. 1 ~ No. 5 DTMF signal transmission level
(Low frequency 0~15.5dBm setting by 0.5dBm step)
The transmission level of DTMF signal is adjusted. (lower frequency)
00000: 0dBm
↓
11111: -15.5 dBm (-0.5dBm x 31)
SW-B6 No. 6 ~ No. 8 Reserved
Set to "0".
SW-B7 No. 1 ~ No. 5 DTMF signal transmission level
(High frequency 0~15.5dBm setting by 0.5dBm step)
The transmission level of DTMF signal is adjusted. (higher frequency)
00000: 0dBm
↓
11111: -15.5 dBm (-0.5dBm x 31)
SW-B7 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/su-
per-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 Reserved
Set to "0".
SW-C1 No. 7 MTF correction in half tone mode
This allows selection of MTF correction (dimness correction) in the half
tone mode.
When "NO" (=1) is selected, the whole image becomes soft and mild.
Clearness of characters will be reduced. Normally set to "YES" (=0).
SW-C1 No. 8 Reserved

SW-D1 No.1 ~ No. 4 Number of rings for auto receive
(0~15rings setting)
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 nine 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 maximum of 5.
SW-D1 No. 5 Automatic switching manual to auto receive function
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 re-
main 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. 7 CI detect frequency
Detection frequency of ring signal for auto reception is set.
When set to No. 6=0, No. 7=0, frequency is set to PTT recommendation.
When set to No. 6=0, No. 7=1, frequency is set to 11.5Hz or more.
When set to No. 6=1, No. 7=0, frequency is set to 13.0Hz or more.
When set to No. 6=1, No. 7=1, frequency is set to 20.0Hz or more.
