I am trying to use the fax machine that I bought from overseas (Panasonic model KX-FC379CX), when I tried to use it, it tells me that the transmission failed, the error report part of the error showed below :
How can I adjust that , because when i went through the manual I could not find that option!!!!
Regards
Telecom recommends the fax machine be adjusted for a transmission level of -15.0 to -17.0 dBm as the optimum range. Contact supplier for adjustment.
