RF emissions
CISPR11
Group 1
Aurical Aud 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.

Class B
Aurical Aud is suitable for use in all environments, including domestic environments and those
directly connected to the public low-voltage power supply network that supplies buildings used
for domestic purposes.

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