I'm somewhat hesitant to poke around inside the camera with my fat fingers. Although, the batteries died long ago - and there's no film in the camera. Shutter speed dial works OK. The camera has been sitting in a camera bag in a closet for about 20 years. I'll try fresh batteries and see if that works, and I'll make sure to clean the contacts before inserting the new batteries.
Thanks for the suggestions. I'll let you know how it turns out.
