front-panel painted surface.
2. Using your fingers, pull the nameplate completely off of the front panel and discard it.
3. If any adhesive remains on the front panel surface, it can be removed by rubbing it with your finger. Do not
use a sharp object to remove this adhesive. If necessary, the surface can be cleaned with isopropyl alcohol.
Install the New Nameplate

adhesive with your fingers as this may affect its ability to adhere to the front panel surface.
2. Loosely align the new nameplate over the recess in the front panel and apply lightly.
