This is a rare item that is no longer sold, and especially the white color is not often available even used. I previously purchased it on Mercari, but I am selling it because I haven't used it much. Even when combined with the previous owner, the usage period is less than a month. As stated in the manual, this is used with an adapter. There is a place to insert batteries, but it's for backup purposes, so it won't run on batteries alone. It seems to be for backing up settings in case of a power outage. Original price: approximately 11,000 yen It has space to place a tablet and seems useful to have around electronics like computers.
