Hi folks.
Last month I replaced the battery in the wheel sensor and today there's a blank screen on the main body.
I removed the outer cover but cannot flip off the cover over the battery itself.
I've tried unscrewing it but there's nothing to grab/ grip.
Nowhere for a screwdriver to fit in.
I hope the picture explains my situation.
I think old age has worked it's magic.
Any thoughts or tips much appreciated.
Matt
