Compliance to the Electromagnetic Emissions
TheDSL-8001 system is intended for use in the electromagnetic environment specified below.
Emissions Test Compliance Electromagnetic Environment - Guidance
RF Emissions
CISPR 11 (FA)
EN 55011 (CE)
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.

recommended that the
DSL-8001 is equipped with an
internal battery (option) or is
powered from an uninterruptible
power supply.
