Removal and Installation

Front-Panel Knobs

4–8
You will need angled-tip tweezers.
NOTE.
If you are not removing the front panel, you do not need to remove the
front-panel knobs; you can proceed to trim removal.
1. To remove a knob:
a. Hold the knob that you want to remove and pull it straight out from the
front panel about 1/4 inch to create some clearance between the base of
the knob and the front panel.
b. Insert the angled-tip tweezers between the knob and front panel and use
them to remove the knob. (See Figure 4-2 on page 4-8.)
c. For replacement knob part numbers, refer to the exploded view and
replaceable parts table. (See Figure 5-3 on page 5-9.)
