1. Cleaning
Danger!
Power Panel devices may only be cleaned when switched off. This is to prevent
unintended functions from being triggered when touching the touch screen or
pressing the buttons.
A moist towel should be used to clean the Power Panel device. When moistening the cloth, use
only water with detergent, screen cleaning agent, or alcohol (ethanol). The cleaning agent
should be applied to the cloth beforehand, not sprayed directly on the Power Panel device! Never
use aggressive solvents, chemicals, scouring agents, pressurized air or steam jet.
Information:
Displays with touch screens should be cleaned at regular intervals.
