Panasonic cassette player. Model: RQ-L11 Uses 2 AA batteries. Can also use an external DC 3V power supply. It worked properly with my external power supply. (External power supply not included.) Tape playback, pause, fast forward, and rewind functions work without issue. The record button can be pressed, but recording did not work in the tested range. It is likely playback-only. I don't feel any particular problems with the operation of the other buttons. There are some scratches on the surface, to the right of the speaker, but no other noticeable scratches. Please be aware that this is a used item before bidding.
