Warnings
This device complies with part 15 of the FCC rules and with RSS-210 of Industry
Canada. 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 opera tion.
Caution: Any changes or modifications by the user could void the user’s authority to
operate the equipment!
NOTE: 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 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 b e 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:
• Reor ient or reloc ate the rec eiving antenna .
• Increas e the separation b etween the e quipment 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.
IMPORTANT NOTE:
FCC Radiation Exposure St atement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance of
20 cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
