Re: Question about Stealth Cam.
The "R" is rewind, "MU" is minute up, "MD" is minute down, "P" is how many pictures you want.
When you turn the camera OFF or replace bateries, and turn it back on the film will wind 3 exposures, if there isn't enough film to wind that far the "E" will appear on the screen. Just put it on "TEST" and push the "R" and it should rewind. The "E" will also appear if a new roll of film doesn't wind correctly.
There is a toll free number on the inside cover. I had to call it a few times before I learned how to use it propperly.
