Note:
POTENTIAL FOR RADIO/TELEVISION INTERFERENCE (for U.S.A. only)
This product has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
The product generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If the product does cause harmful interference to radio or television
reception, which can be determined by turning the product on / off, 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 product and the receiver.
- Connect the product into an outlet on a circuit which is different from what the receiver is
connected to.
- Consult the dealer or an experienced radio / TV technician for help.
