To remove the front panel assembly
1 Perform the following procedures:
• “To remove the cabinet” on page 80
2 Insert a flat-blade screwdriver under the center of the
intensity knob and gently twist the screwdriver as you pull
the knob off.
Using a twisting motion rather than prying prevents marking
or damaging the front panel.
3 Remove the T6 screws securing the BNC assembly to the
deck.
This step helps prevent the BNC connectors from binding
when removing and reinstalling the front panel.
