Cleaning
Cleaning the touch screen
When cleaning the front surface of the NFI touch screen, use any chemical 
that does not corrode glass. The touch screen will function, even if its front 
surface is pitted or damaged by a chemical.
Warning
To reduce the risk of electric shock which could result in serious personal injury 
or death, do not open the power supply in the ET 350 monitor. It contains 
hazardous voltages. The power supply has no user-serviceable parts or 
adjustments inside.
Caution
To reduce the risk of minor or moderate injury from contact with cleaning 
solutions or fluids, through means such as ingestion and skin contact, refer to 
the cleaner manufacturer’s material safety data sheet and follow all instructions 
and recommendations.
Important
Clean the back of the touch screen (the surface that is inside the touch screen 
and is exposed to the graphic underlay) using only cleaning solutions and 
materials designed for coated optics. The back of the touch screen is covered 
with a coating that is easily damaged by commercial glass cleaners or a regular 
cloth.
