Mains power quality should be that of a typical commercial or hospital
environment. If the user of this product requires continued operation during
power mains interruptions, it is recommended that the product is powered
from an un-interruptible power supply or a battery.
U
T
is the a. c. mains voltage prior to application of the test level.

Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which this product is used exceeds
the applicable RF compliance level above, this product should be observed
to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating this product.
Interference may occur in the vicinity of equipment marked with the
following symbol:

wireless communication
equipment refer to table
9 of IEC 60601-1-2:2014
Portable and mobile RF communications equipment should be used no
closer than 30 cm to any part of this product including cables.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
