1. Electromagnetic emission
Guidance and manufacturer's declaration – electromagnetic emission
This device is intended for use in the electromagnetic environment specified below.
The customer or the end user of the device should assure that it is used in such an environment.
Emission test Compliance Electromagnetic environment - guidance
RF emission – CISPR 11 Group 1
This device uses RF energy only for its internal
function. Therefore its emissions are very low and
are not likely to cause any interference in nearby
electronic equipment.
Emission – CISPR 11 Class A
This device is suitable for use in all establishments
other than domestic and those directly connected to
the public low voltage power supply network that
supplies buildings used for domestic purposes.

The quality of the mains voltage
should be that of a typical commercial
or hospital environment. If the use of
the device requires continued
operation during mains power
outages, it is recommended to use
the device with an uninterruptible
power supply or batteries.

If image distortion occurs, it may be
necessary to position the device
further from sources of power
frequency magnetic fields or to install
magnetic shielding. The power
frequency magnetic field should be
measured in the intended installation
location to assure that it is sufficiently
low.
