For models with an optional barcode reader:
Do not look directly at the red beam for an extended
period or point the barcode reader at another person's
eyes.

Clean dust and other debris on the AC plug regularly.
If dust or other debris accumulates on the plug, humidity,
etc. may cause a defect in the insulation, which may result
in a fire.
• Pull the plug, and wipe it with a dry cloth.
Pull the plug if the computer is not being used for a long
period of time.
