Trying to install a new lexan DMD window in my speaker panel on AFM. The old window is secured with those pronged pressure tabs that slide on the speaker panel mounts. Is there a trick to removing them without breaking them or the the panel mounts they are secured to? Any insight would be appreciated.

Thanks, that was what I figured I had to do, wasn't sure if the tabs are easily broken by doing this. Hopefully I can reuse the lock collars if I don't distort them to much with the pick tool. What a shit design!

Mission accomplished. My 90 degree pick worked great. I pried one tab up on each of the lock collars and successfully got all of the off intact and was able to reuse them. Thanks for the reassurance on how to do this the best way. A new clear window makes a big difference, especially with a color DMD for that added restore touch on a DMD machine.
