Certifications
cULus. Listed and cUL Listed to UL 6500 and CSA E60065. Au-
thorized under Verification provision of FCC Part 15 as a Class B
Digital Device.
This Class B digital apparatus complies with Canadian ICES–003.
Conforms to European Union Directives, eligible to bear CE
marking. Meets European Union Low Voltage Requirements:
Certified to EN 60065. Meets applicable tests and per-
formance criteria in European Standard EN55103 (1996) parts 1
and 2, for residential (E1) and commercial and light industrial
(E2) environments.
NOTE: EMC conformance testing is based on the use of sup-
plied and recommended cable types. The use of other cable
types may degrade EMC performance.
EMC conformance testing is based on the fact that the computer
is used for setup purposes only and disconnected during EMC
testing.
