Releasing front panel from deck of instrument
When tab B is released, be careful that the sheet metal tab of front-panel
ground input clears the softkey circuit board. The circuit board may be
depressed slightly with a screwdriver to avoid damage to the circuit board.
Rotate the front panel out until the bottom clears the rear of the
4
assembly, then lift the front panel to free the hooks on top.
When installing the front panel, make sure that the power switch shaft is
aligned with its mating hole in the front panel.
The front panel swings in to engage the two retainer tabs. Before attempting
to engage the retainer tabs, make sure that the six hooks on top of the front
panel are fully engaged with their mating holes in the sheet metal.
