reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one 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 Subpart B of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate this equipment.
