RF emissions
CISPR 11
Group 1
The LSU 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 LSU 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.
Harmonic emissions
