1 Perform the following procedures:
• “To remove the bottom cover” on page 145
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 on the screwdriver rather than
prying prevents marking or damaging the front panel.
