Electromagnetic emissions
Emissions Test Compliance Electromagnetic Environment — Guidance
Radio Frequency (RF)
Emissions
CISPR 11
Group 1 The Smart Scale 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 Smart Scale 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.

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