Guidance and manufacturer’s declaration – electromagnetic emissions
The display is intended for use in the electromagnetic environment specified below. The customer or the user of the
display should assure that it is used in such an environment.
Emissions Compliance Electromagnetic environment-- guidance
RF emissions
CISPR 11
Group 1
The display series uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.
RF emissions
CISPR 11 Class A The display series is suitable for use in all establishments, including
domestic establishments and those directly connected to the public
low-voltage power supply network that supplies buildings used for
domestic purposes.
Harmonic emissions
IEC 61000-3-2 Not Applicable
Voltage fluctuations/
flicker emissions Not Applicable

Mains power quality should be that of a
typical commercial or hospital environment.
If a dips or an interruption of mains power
occurs, the current of the display series may
be dropped off from normal level, it may be
necessary to use uninterruptible power
supply or a battery.
