Guidance and manufacturer's declaration - electromagnetic emissions
The device is intended for use in the electromagnetic environment specified 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 RF
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 supplies buildings used for domestic purposes.

EMC (ELECTROMAGNETIC COMPATIBILITY):
* 1 For the regions where the rated voltage is 220 V or greater, this device complies with class A. For the regions where the
rated voltage is 127 V or less, this standard is not applicable.
* 2 For the regions where the rated voltage is 220 V or greater, this device complies with this standard. For the regions where
the rated voltage is 127 V or less, this standard is not applicable.

Mains power quality should be that of a typical
commercial or hospital environment. If the user 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.
