gently pulling it away from the sides of the instrument case and swinging it up or down.
To remove the handle, swing the handle below the bottom surface of the case and back
until the orientation arrows on the handles line up with the orientation arrows on the
mounting ears. With the arrows lined up, pull the ends of the handle away from the
case.

Remove Mounting Ears — Remove the screw that secures each mounting ear. Pull
down and out on each mounting ear.
NOTE

of the chassis and the left ear to the left side of the chassis. Each ear is marked
“RIGHT” or “LEFT” on its inside surface.

Remove Rear Bezel — To remove the rear bezel, loosen the two screws that secure the
rear bezel to the chassis, and then pull the bezel away from the case.
