UX-A260U SW-A5 No. 5, No. 6 Digital cable equalizer setting (Reception for Caller ID) Line equalization when reception for CALLER ID is to be set according to the line characteristics. Setting should be made according to distance between the telephone and the telephone company central switching station. SW-A5 No. 7 Error criterion Used to select error criterion for sending back RTN when receiving image data. 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 connect Delay time between the dial key input and line connection under the auto dial mode. SW-A5 No. 8 Anti junk fax check When using the Anti junk fax function, set to "1". SW-A6 No. 1 Reserved Set to "0". 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 equalizer 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 transmission mode (User press the START key after waiting for the fax answering signal from handset or speaker). RAPID01 CML RELAY ON DIALLING No.6 0 0 1 1 No.7 0 1 0 1 0sec 1.5sec 3.0sec 4.5sec 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 CML RELAY ON DIAL DATA No.1 0 0 1 1 No.2 0 1 0 1 1.7sec 3.0sec 3.6sec 4.0sec 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 key When setting to 1, the mode is changed by pressing the key from the pulse dial mode to the tone dial mode. 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 connection. 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-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 possible 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 regulations. 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-B2 No. 3 Reserved Set to "0". SW-B5 No. 6 ~ No. 8 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-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) 2 - 15
