Notice the pattern of push-buttons on the controller, and the pattern of holes in the front 
panel. Match the patterns, and insert the controller push-buttons through the holes in the 
front panel. Wiggle the controller a bit as you gently attempt to insert it into the front 
panel. 
 
You’ll most likely note that mis-alignment of some of the LEDs stops the controller from 
fully seating on the mounting standoffs and stops the LEDs from protruding evenly 
through the front panel. 
 
Make a note of which LEDs are misaligned. Remove the controller, and carefully adjust 
those LEDs as needed to fit the front panel holes. You may have to repeat this procedure 
3 to 5 times, but if you make small adjustments, everything will line up. It sometimes 
help to wiggle the controller PCB when you’re close. 
 
At some point, the controller will seem to pop through the front panel as all the LEDs 
pass through the accompanying front panel holes. The forward edge of the LEDs extends 
about 1/16” past the front panel. From this point on, it will be easy to remove and re-
install the controller PCB into the front panel as needed so long as you don’t bump into 
the LEDs. The switches will guard the LEDs from most casual bumps as you continue the 
next section’s assembly.

Install the Controller PCB into the Front Panel 
Locate qty 4 of the 4-40x1/4” zinc/plated (silver colored) Philips head sems screws (with 
built in lockwasher) and a Philips head screw-driver. 
 
Fit the controller PCB into the front panel. Check as before for even protrusion of all the 
LEDs through the front panel. 
 
Loosely install the 4-40 screws through the 4 holes in the corners of the controller PCB 
into the mounting standoffs on the chassis front panel.
