ACCESSING THE INTERIOR OF THE VU METER PANEL The VU meter panel is opened by removing the screw at the left and right front of the panel. ACCESS SCREWS Arrakis Systems inc. - Page 8 Replacing Slide Faders, Switches, and other parts Slide faders and switches are soldered onto the PC board and should be replaced at the factory if at all possible. The procedure requires proper tools, and it can be difficult to remove the parts without damaging traces or pads on the PC board. Also, the switches are very sensitive to temperature and duration during the soldering process and can be electronically damaged or destroyed when being soldered.
