This is a color intercom from the Showa era. I replaced it because the image on the indoor unit sometimes flickered. Please understand that it is a junk item. It is for parts or as a Showa retro item. Includes the outdoor unit, indoor unit, instruction manual, setup manual, and mounting frame. The screws on the outdoor unit were stripped, so I pried it open. See images 8 and 12. Please refrain from purchasing if you are sensitive to used items. Thank you.
