FCC Information to User
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment 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 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 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 con-nected.
• Consult the dealer or an experienced radio/TV technician for help.
Caution
Modifications not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
FCC Compliance Information : This device complies with Part 15 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.
IMPORTANT NOTE:
FCC RF Radiation Exposure Statement:
This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20 centimeters between the radiator and your body. This
transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
