●
Compliance to the Electromagnetic Emissions
The DS-7000 is tested under the following electromagnetic environment.
Emissions Test Compliance Electromagnetic Environment – Guidance
(
The DS-7000 is intended for use in the electromagnetic
environment specified below.)
RF Emissions
CISPR 11
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
CISPR 11
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.
