FO-1470TH
SW-A5 No. 5, No. 6 Reserved
Set to "0".
SW-A5 No. 7 Error criterion
Used to select error criterion for sending back RTN when receiving im-
age data.
SW-A5 No. 8 Anti junk fax check
When using the Anti junk fax function, set to "1".
SW-A6 No. 1 Auto gain control (MODEM)
When this mode is enabled, if the reception signal level is under 31dBm,
the modem itself controls the signal gain automatically.
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 discon-
nected immediately.
Bit1= 1: When DIS signal is received during RX mode, the line is discon-
nected 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.
SW-A6 No. 5 Equalizer freeze control 7200BPS only
Setting which specifies SW-A3 No. 6 control only in the condition of
7200BPS modem speed.
SW-A6 No. 6 CNG transmission in manual TX mode
When set to "1", fax transmit the CNG signal in case of manual trans-
mission mode (User press the START key after waiting for the fax an-
swering signal from handset or speaker).
SW-A6 No. 7 Reserved
Set to "0".
SW-A6 No. 8 Modem speed automatic fallback when RX level is
under -40dBm
When set to "1", if fax signal level is under -40dBm during reception,
machine selects the slower modem speed automatically.
It is effective when noises occur on the received document due to the
long distance communications.
SW-B1 No. 1 ~ No. 4 Recall interval
Choice is made for a redial interval for speed and rapid dial calls.
Use a binary number to program this. If set to 0 accidentally, 1 will be
assumed.
SW-B1 No. 5 ~ No. 8 Recall times
Choice is made as to how many redials there should be.
SW-B2 No. 1 Dialing pause (sec/pause)
Pauses can be inserted between telephone numbers of direct dial con-
nection. Selection of 4 sec or 2 sec pause is available.
SW-B2 No. 2 Dial tone detection (before auto dial)
Used to set YES/NO of dial tone detection in auto dialing.
SW-B2 No. 3 Reserved
Set to "0".
SW-B2 No. 4 Busy tone detection (after auto dial)
Used to set busy tone detection in auto dialing.
SW-B2 No. 5, No. 6 Waiting time after dialing
This is time waiting for the opponent's signals after dialing.
SW-B2 No. 7, No. 8 Reserved
Set to "0".
SW-B3 No. 1 ~ No. 5 Reserved
Set to "0".
SW-B3 No. 6, No. 7 Auto dial mode Delay timer of before line con-
nect

SW-B3 No. 8 Hold key
Used to set YES/NO of holding function by the HOLD key.
SW-B4 No. 1, No. 2 Auto dial mode Delay timer of after line connect
Delay time between the line connection and dial data output under the
auto dial mode.
RAPID01
SW-B4 No. 3 Dial mode
When using the pulse dial, set to 1. When using the tone dial, set to 0.
SW-B4 No. 4 Pulse → Tone change function by
When setting to 1, the mode is changed by pressing the
pulse dial mode to the tone dial mode.
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 unsuc-
cessful 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 regula-
tions.
SW-B5 No. 1 ~ No. 5 DTMF signal transmission level (Low)
The transmission level of DTMF signal is adjusted. (lower frequency)
00000: 0dBm
