Cover Removal and Replacement
Version 1
The Version 1 unit includes a combined front cover/frame lid. Follow these steps to remove
and replace the Version 1 front cover and lid:
1 Disconnect both AC power cords.
WARNING: You can receive an electric shock from exposed parts of the power
supplies. Ensure that you remove AC power from both power supplies before you
open the cover.
2 Remove 15 screws from the one-piece front panel/lid (12 on the top; 3 on the bottom).
3 Pull the scrolling knob straight off its shaft and then carefully slide the lid off the unit.
CAUTION ! Do not tilt the front cover/lid as you remove it. This may damage circuit
board components.
4 After you have completed servicing, replace the cover.
Approach the unit with the cover at a 10
°
angle, slide the front over the encoder shaft,
and then, with the corner angle past the mounting ear, gently lower the lid and slide it
into position.
