Sanyo Slim & Trim. For Parts/ Not Working. I put batteries in to test. The radio seems to work fine and uses 2 “N” size batteries. The calculator, however, does not work, the LCD is black. It uses a 2032 coin battery. The unit has probably been lightly used. The battery terminal is slightly corroded (pictured). The black case has smudges, the plastic is a bit warped from continued removal of the unit. Box has a few dents and stains. The instructions have a stain on the front. Black case, original earphone, new batteries (kept in a plastic bag). Please make sure you take a look at the pictures and feel free to ask any questions. Thanks for looking, have a great day!
