I received this from a family member, but I haven't had a chance to use it, so I'm putting it up for sale. It's USB rechargeable, and if you can charge it, you can watch one-seg TV and listen to the radio wirelessly. The key is how well one-seg and radio signals are received in your area. (It cannot be used where one-seg and radio signals are not available. When reception is poor, a "Cannot receive" message will appear in the center of the screen (photos included)) I have confirmed that the one-seg TV and radio work. (I have not tested other functions such as recording) The body size is approximately 145 x 84 x 14 mm (excluding protrusions). Of the accessories, the AC/DC adapter, external antenna conversion cable, and earphones are missing, but the USB power cable, instruction manual, and strap are included. You can charge it with a general small appliance USB charging AC/DC adapter. Please see the photos for detailed specifications. It's almost unused, including by the family member who gave it to me. Because of the way it was stored, there are some spots visible depending on the viewing angle of the screen, but they do not particularly affect viewing. The box and case are also included, but they are in the condition shown in the photos (the box has torn and bent corners).
