Remove Handle — The handle serves as an adjustable tilt-bail. Adjust its position by
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 from the case.
Remove Mounting Ears — Remove the screw that secures each mounting ear. Pull down
and out on each mounting ear.
When re-installing the mounting ears, make sure to mount the right ear to the right
side 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 captive screws that se-
cure the rear bezel to the chassis. Pull the bezel away from the case.
Removing Grounding Screws — Remove the two grounding screws that secure the case
to the chassis. They are located on the bottom of the case at the back.
Remove Chassis — To remove the case, grasp the front bezel of the instrument, and
carefully slide the chassis forward. Slide the chassis out of the metal case.
If you need to gain access to the components under the motherboard shield to trou-
bleshoot them, remove the shield. It is secured to the motherboard by a single screw.
