Do Not Remove the Instrument Cover

Only qualified, service-trained personal who are aware of the hazards involved 

should remove instrument covers. Always disconnect the power cable and any 

external circuits before removing the instrument cover. 

Do Not Modify the Instrument

Do not install substitute parts or perform any unauthorized modification to the 

product. Return the product to an Keysight Sales and Service Office for service 

and repair to ensure that safety features are maintained. 

In Case of Damage

Instruments that appear damaged or defective should be made inoperative and 

secured against unintended operation until they can be repaired by qualified 

service personnel.
