2 – 19
SW-B4 No. 5 Dial pulse make/break ratio (%)
When using the 33% make ratio pulse dial, set to "0".
When using the 40% make ratio pulse dial, set to "1".
SW-B4 No. 6, No. 7 Reserved
Set to "0".
SW-B4 No. 8 Recalling fixed only one time when dialing was
unsuccessful without detecting busy tone signal
When dialing results in failure since the busy tone cannot be detected,
recalling is fixed to one time.
Supplementary explanation
If time-out termination is made when dialing, only single recall is possi-
ble even if the setting time of recalls (SW-B1 No. 5 - No. 8) has been
set to some times. This soft switch is added in order to meet FCC.
SW-B5 No. 1 ~ No. 5 DTMF signal transmission level (Low)
The dial signal of a push button telephone is called DTMF (dual-tone
multi-frequency). These tones consist of two signals, one from a high
group of frequencies and one from a low group of frequencies. Repre-
sent each of the push button telephone characters shown as below.
The transmission level of DTMF signal is adjusted. (lower frequency)
00000: 0dBm
↓
11111: -15.5 dBm (-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 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
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 diffi-
culty receiving faxes, reduce the number of rings to a maxi-
mum 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 Reserved
Set to "0".
SW-D1 No. 7, No. 8 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 recommenda-
tion.
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.
SW-D2 No. 1 ~ No. 3 Distinctive ringing setting (PATTERN 4 and 5
are for CANADA only)
This function allows reception of services offered by USA and Canada
telephone companies in which the customer contracts with the tele-
phone company to have up to 4 telephone numbers (USA) or 6 tele-
phone numbers (Canada) established for one line.
Each telephone number is signaled by a different ringing pattern, and
the customer can allocate each number to a specific use.
