Canon Powershot Pro1 will not switch on

Thanks Markus. Here is the image of the camera's battery compartment. There appears to be what could be a switch below the battery connection rods. ANy thoughts? Hopefully you can see the image and it is large enough to see the detail.

"HI,

I was gifted a Canon Powershot 1 Pro.

We are having a bit of trouble making

the zoom lens extend beyond the 28mm

mark. In other words no power zoom.

Also manually extending the zoom

feature is hit and miss. The quick use

guide is not much help.

thanks,

two old camera dummies"
