EMC Regulatory Notices

The Federal Communications Commission (FCC) and other worldwide regulatory agencies and standards define two classes of products for defining the limits on the electromagnetic emissions of electronic devices. These limits are based upon the intended environment the products are intended to operate in and their expected proximity to nearby broadcast radio and television receivers. To determine the classification of a specific Lexmark product, consult the user guide that comes with the product or contact your local Lexmark representative.

Class A: Products intended for use in non-residential or commercial environments where it is not expected that they would be located within 10 meters of broadcast radio and television receivers.

Class B: Products intended for use in residential and domestic environments. Class B products may also be used in non-residential and commercial environments.

The Class B limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a residential environment. The Class A limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Contact your Lexmark technical support representative or an experienced radio or television service representative for additional suggestions.

In order to reduce the possibility of interference to radio or television services, only properly shielded and grounded USB, parallel or RS232 cables should be used. Use of a cable not properly shielded and grounded may result in a violation of FCC regulations.

Consult the user guide provided with your product for additional information and notices.
