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
z 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
z This device complies with Part 15 of 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.
Note:“Changes or modifications to this unit not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.”
