-- Battery Compartment Cover (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=831)

FYI, on numberous occasions my Visor's battery compartment cover has come loose only to be luckily found. Now I have put a small piece of scotch tape on the cover adhering it to the Visor's back cover and the issue is solved.
