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. Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

(1)thisdevicemaynotcauseharmfulinterference,and

(2) this device must accept any interference received, including interference that may cause undesiredoperation. Changes or modifications to this unit not expressly approved by the party responsible for compliancecouldvoidtheuser'sauthoritytooperatetheequipment.
