Use a 100% cotton cloth or micro-fiber cloth for cleaning.
If the remote control or bezel is dirty to the point where you cannot simply dry wipe it, please lightly
dampen the cleaning fabric with clean water and wipe it.
Use only lightly dampened fabric to avoid malfunction and possible permanent damage to electronic
components.
