Removing and Replacing Labels
Preparation
1 Tu r n t h e d e v i c e o f f .
2 Disconnect AC power and remove the battery.
Removal
1 Using a sharp tool such as a utility knife, pick up one corner of the old label.
2 Peel the label up by pulling slowly and evenly on the loosened corner.
Replacement
1 Clean the surface:
a Remove any adhesive residue by rubbing the dry surface with your finger and “rolling up” the
adhesive residue.
Solvents are ineffective, as is scraping with a tool.
b Clean the surface with isopropyl alcohol. Allow it to dry.
2 Peel the new label off the backing.
Avoid touching the label adhesive, as this may prevent the label from bonding properly.
3 Apply the label:
a For the Control Panel label, align around the Buttons and Switch first.
b Align one edge of the label with the recess on the case, then roll the label slowly into position.
c Press firmly all over the label, especially the edges, to ensure it adheres to the case.
To Complete the Replacement
Visually inspect the device to ensure that you applied the labels correctly. It is not necessary to run
any Performance Verification and Safety testing.
