Federal Communication Commission Interference
Statement
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 connected.
Consult the dealer or an experienced radio/TV technician
!
for help.
FCC Caution: To assure continued compliance, any
changes or modifications not expressly approved by the
party responsible for compliance could void the user's
authority to operate this equipment. (Example - use only
shielded interface cables when connecting to computer or
peripheral devices).
FCC 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 0.5 cm between the radiator and your
body.
12 1 3
This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
The antennas used for this transmitter must be installed to
provide a separation distance of at least 0.5 cm from all
persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
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.
IC
This device complies with Industry Canada RSS-210
ISSUE 2 standards. Operation is subject to the following
two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including
interference that may cause undesired operation of the
device.
Le présent appareil est conforme aux CNR d'Industrie
Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible
d'en compromettre le fonctionnement.

To reduce the risk of fire or electric shock, do not expose
this apparatus to rain or moisture.
2. UNDER WET LOCATION:
Apparatus should not be exposed to dripping or splashing
and no objects filled with liquids, such as vases should be
placed on the apparatus.

literature accompanying this unit.
Disposal
2005 -08-1 3
Dispose of any unusable devices or batteries
responsibly and in accordance with any applicable
regulations.
Disposing of used batteries with domestic waste is
to be avoided!
Batteries / NiCad cells often contain heavy metals
such as cadmium(Cd), mercury(Hg) and lead(Pb)
that makes them unsuitable for disposal with
domestic waste. You may return spent batteries/
accumulators free of charge to recycling centres or
anywhere else batteries/accumulators are sold.
By doing so, you contribute to the conservation of
our environment!
