Panasonic TV doorphone, VL-SV36KL, with camera unit, with instruction manual. - Brand: Panasonic - Model: VL-SV36KL - Manual: With instruction manual - Function: TV doorphone - Accessories: Camera unit (VL-MV36KL) I replaced it because I needed a wireless handset due to family circumstances. It was working without any problems. I don't think it's suitable for home use due to aging, but how about using it for testing before replacement, etc.? The indoor main unit is yellowish. As shown in the photo, it is directly connected. There is no 100-volt cord that was removed, so an electrician's license is required. Thank you for looking.
