Compliance to the Electromagnetic Emissions
The DS-7300 system is intended for use in the electromagnetic environment specified below.
Emissions Test Compliance Electromagnetic Environment - Guidance
RF Emissions
CISPR 11
/EN55011
Group 1
The equipment uses RF energy that is necessary for the
internal functioning of the equipment itself. Therefore, its
RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.
RF Emissions

Class A
This equipment is suitable for use in all establishments other
than domestic and those directly connected to a low-voltage
power supply network which supplies buildings used for
domestic purposes.
Compliance to the Electromagnetic Immunity (1)
The DS-7300 system is intended for use in the electromagnetic environment specified below.
It should be assured that the DS-7300 system is used in such an environment.
