vice, 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 or
more of the following measures:
─ Reorient or relocate the receiving antenna.
─ Increase the distance 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 of the FCC rules. The operation is subject to the following
two conditions:
─ this device may not cause harmful interference, and
─ this device must accept any interference received, including interference that may cause
undesired operation.
■ This device fulfils the provisions of the Industry Canada Licence, with the exception of the RSS
rules. The operation is subject to the following two conditions:
─ this device may not cause harmful interference, and
─ this device must accept any interference received, including interference that may cause
undesired operation.
In order to ensure permanent compliance with the FCC rules, unless explicitly approved by

Warning notices indicate three levels of danger identified by the corresponding signal word:
Signal term Meaning Consequences of non-compliance
DANGER Warns of imminent danger Will very likely result in death or severe injury
WARNING Warns of potentially imminent danger May result in death or severe injury
CAUTION Warns of a potentially dangerous situa‐
tion
May result in moderate physical injury
