13.3.3. Ground-link Internal Jumpers
The unit has jumpers that are used to balance either the input, or the output, about
ground. By default these are not fitted when the unit leaves the factory.
To get inside the RB-PLI6, observing anti-static precautions, undo the four crosshead
screws on the back panel at the far left and far right of the panel (2 at each end). Also
undo the small brass screws, which hold the top and bottom panels to the rear panel.
The rear panel should slide backwards out of the unit together with the main circuit
board.
