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

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 & 74 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).
