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.
