particular attention to plugs, wall outlets, and the point where the cord
exits the appliance.
Do not press strongly upon the panel with a hand or sharp object such
as nail, pencil or pen, or make a scratch on it, as it may cause damage

Avoid touching the screen or holding your finger(s) against it for long
periods of time. Doing so may produce some temporary or permanent
distortion/damage to screen.
