I have a Lumapower MRV and can't get it to give me more than one mode. On the website, it's explained in detail. They say to losen the engine 3/4 turn from the battery tube. I feel stupid. Any suggestions?
Both of mine are exactly 3/4 of a turn. I just tried them both. My thought is that the terminology isn't really correct. Instead of loosening the light engine from the head....loosen the battery compartment from the head and light engine. In other words, loosen it below the heat sink collar.
If you're already doing this and still getting only one mode, unscrew the battery compartment completely. Reach into the back of the light engine with your finger and try clicking that little copper button. If you can feel and hear it clicking that should mean that it's operating correctly.
The one last thing you can try is tightening the little black plastic disk down inside the heatsink collar that surround the button that you were just pressing. Use a small spanner or an icepick and try to turn the disk clockwise to tighten it. If it is loose it could be causing your problem.
If you need more detailed help with any of the above info just repost here or PM me.
