The labels on the buttons or keys of the remote control may wear off or fade away. This issue may be caused by the use of cleaning solvents on the keys or residue on the fingertips of the individual using the remote control.
If the buttons or keys of the remote control are too warn or faded to use, the remote may need to be replaced.
