Replacing a front bezel label
A front bezel label may be replaced without disassembling the light source. To replace
a front bezel label, use the following procedure.
1. Disconnect the power cord.
2. Place the light source on its rear panel so the front bezel is facing up and can be
easily accessed.
3. Note the exact placement of the label on the bezel. With a pointed instrument,
gently pry and lift up a corner of the label enough to grasp it with your fingers.
4. Gently peel it back until it is off the bezel.
5. Remove the protective backing from the replacement label.
6. Carefully center the cutout(s) of the replacement label over the component
opening(s) on the bezel, aligning the label corners properly. Press the whole label
into place.
