This is a telephone with a fax function. The main unit only, no handset or manual included. I mainly used it for sending faxes. I used it because there were still some clients who only accepted orders via fax, but I no longer have any transactions with them, and I've also canceled my landline, so I'm putting it up for sale. I was using the fax transmission function until recently, so it works without any problems. For receiving, the paper ejection didn't work well sometimes, and the thermal roll ran out, so I was checking the received faxes as images using utility software on my PC. Searching for "SP-NA540" will bring up the download page for the utility software. It should function normally after installing it and changing the compatibility settings in the properties.
