Hello,

I know of two lock icons implemented on the Karma.

One is only displayed when the lock switch is activated, and the user tries to power the unit on. This one is a giant padlock taking up most of the screen, it either goes away after 3 or so seconds and powers the unit back off again, or if the lock switch is deactivated during the padlock being displayed power up will resume.

The other lock icon is tiny and appears at the top of the player screen along with the shuffle icon and others.

If you are seeing the giant lock icon whilst the player is running, you probably have some sort of problem that is causing the unit to reset, this could either be a firmware issue, or a hardware fault. Not having the lock switch activated would solve the giant padlock side of the problem, but you would still suffer periodic resets.
