Electromagnetic Compatibility Information
Table 1
Guidance and declaration of manufacturer – electromagnetic emissions
The device is intended for use in the electromagnetic environment specifi ed below. The customer or the user of the device should assure that it
is used in such an environment.
Emissions test Compliance Electromagnetic environment – guidance
RF emissions CISPR 11 Group 1 The 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.
RF emissions CISPR 11 Class B The device is suitable for use in all establishments, including domestic establishments
and those directly connected to the public low-voltage power supply network that sup-
plies buildings used for domestic purposes.
Harmonic emissions
IEC 61000-3-2 Class A

of the device requires continued operation during
power mains interruptions, it is recommended that
the device be powered from an uninterruptible
power supply or a battery.
