A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.

If no transmission signal sound is heard, it means that the modem part of the main board is poor. � DTMF TEST : DTMF (Dual Tone Multi Frequency) signal. When you press any key on the number keypad including * and #, you will hear the corresponding key tone.
FAX SETUP
� MODEM SPEED : You can set the maximum modem speed. Communication is done with modem speed automatically set at lower speed when communicating with the modem with lower speed since communication is done on the standard of the side where modem speed is low for transmission/reception. It is better set 26.4KBPS as default setting. � SEND FAX LEVEL : You can set the level of the transmission signal. Typically, the Tx level should be under -12 dBm.
Caution : The Send Fax Level is set at the best condition in the shipment from factory. Never change settings arbitrarily.
� ROM TEST : Use this feature to test the machine'S ROM. The result and the software version appear in the LCD display.

(filename : the latest ROM file name when the downloading) 4. After the download is completed, the system will be automatically initialized.
� RCV FAX LEVEL : - You can set the level of the receiving signal. - The reception level may be too low due to the cable losses. - If it is set to -43 dBm, the reception sensitivity will be between 0 and -43 dBm. If it is set to -48 dBm, the reception sensitivity will be between 0 and -48 dBm.
Caution : The Send Fax Level is set at the best condition in the shipment from factory. Never change settings arbitrarily.
� DTMF HIGH LEVEL : Select high frequency level when dialing in the MF mode.The input range is between 00~15dBm.
