Troubleshooting the Installation of an RNC / RNP:

(for the NCC-1701 or FRT-8373)

BUTTON EXTENSION ISSUES:

Friction:

If you are experiencing any sticking or inadvertent activation of the "Supernice" or "Bypass" buttons on the RNC ("Phantom" or "Invert", on the RNP), make sure the black button extensions can move freely within the counter-bored holes in our front panel. If there is any friction, they may stick slightly, as the button spring on RNC/RNP tries to push it back out. To avoid any wiggle in the extensions, it is necessary for us to maintain a very finite amount of airspace between the extension and the hole in the panel (.005", or less). In high humidity, the plastic button extensions can swell ever so slightly, and create friction.

Solution: Simply use a needle file or micro piece of sandpaper wrapped around a nail, etc., to GINGERLY enlarge the holes in the front panel, for the button extensions. BE CAREFUL!! IT WILL ONLY TAKE A FEW PASSES to enlarge them another thousandth of an inch, to eliminate friction! You don't want them too big, or the button may get excessive wiggle.

LED Lineup:

If the LED's in the FMR unit are slightly vertically offset, it is probably due to the rubber feet on the rear of the unit. Do this:

If the LED's are too high, move the 2 rear rubber feet out of the aluminum channel, and up onto the adjacent aluminum ridge--this will raise the rear of the unit slightly, lowering the front, thus the LED's.

If the LED's are too low, respective to the front panel holes, try a shim underneath the 2 front rubber feet with a 1/32" thick piece of "something", or you can also shim underneath the front gray plastic rim of the unit.

If the LED's in the FMR unit are laterally offset, loosen the black anchor bolt (bottom center of tray), and shift the unit Left/Right until it lines up... carefully re-tighten, maintaining alignment.

A year or so ago, FMR shifted the potentiometers back into the unit, which no longer allowed the pot shafts to lock into our front panel. This is no big deal, as the above tweaks will solve any lineup issues, if necessary. As there are still a great number of the older RNC's out there, we cannot modify our front panel to accommodate just the new ones.

Retrofitting another manufacturer's product is a tough gig, especially given tolerance issues at many points along the manufacturing process, i.e. molding the plastic case, assembly, expansion/contraction, milling tolerances, tool wear, etc., and that's just creating the original unit to be mounted. We do our best to insure tight tolerances on our end, allowing for the above variations, which are out of our control. We are easy to get a hold of, and will always do our best to help, if you have any questions, etc... thanks! :)
