General Information and Safety Practices and Hazards 
10  Agilent Cary 3500 UV-Vis Spectrophotometer User’s Guide 
CE Compliance 
Your Agilent Cary UV spectrophotometer has been designed to comply with the 
requirements of the Electromagnetic Compatibility (EMC) Directive and the Low 
Voltage (electrical safety) Directive (commonly referred to as the LVD) of the 
European Union. Agilent has confirmed that each product complies with the 
relevant Directives by testing a prototype against the prescribed EN (European 
Norm) standards. 
Proof that a product complies with these directives is indicated by: 
  the CE Marking appearing on the rear of the product, and 
  the documentation package that accompanies the product containing a copy 
of the Declaration of Conformity. The Declaration of Conformity is the legal 
declaration by Agilent that the product complies with the directives listed 
above, and shows the EN standards to which the product was tested to 
demonstrate compliance. 
Electromagnetic Compatibility 
EN55011/CISPR11 
Group 1 ISM equipment: group 1 contains all Industrial, Scientific and Medical 
(ISM) equipment in which there is intentionally generated and/or used 
conductively coupled radio- frequency energy which is necessary for the internal 
functioning of the equipment itself. 
Class A equipment is equipment 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. 
This device complies with the requirements of CISPR11, Group 1, Class A as 
radiation professional equipment. Therefore, there may be potential difficulties in 
ensuring electromagnetic compatibility in other environments, due to conducted 
as well as radiated disturbances. 
Operation is subject to the following two conditions: 
1  This device may not cause harmful interference. 
2  This device must accept any interference received, including interference that 
may cause undesired operation.
