The SHARP DZ-H20-BR is a brown doorphone, ideal for electrical supplies. - Brand: SHARP - Model Name: DZ-H20-BR - Color: Brown Thank you for viewing. This was purchased by my father during his lifetime. I don't know when it was purchased. It is unused and still in its bag. The main unit is clean, and the instruction manual and screws are included, but a separately sold terminal box seems to be required. (Please enlarge the instruction manual to view it) As the usage situation is unknown, I would prefer that someone with experience in electrical equipment, etc., purchase it. This item has been stored in a storage shed at home for a long time. Please understand.
