dealer.
– If fluid gets in your mouth, gargle thoroughly with clean
water such as tap water and consult a doctor
immediately.
– If your skin or clothing comes in contact with fluid,
immediately wash the affected skin or clothing with
water. If you experience skin irritation, consult a doctor.
• To avoid leakage, generation of heat or explosion:
– Never heat, disassemble or modify the battery, nor
dispose of it in a fire.
– Do not attempt to pierce with a nail, hit with a hammer
or step on the battery.
– Do not drop the product or subject it to strong impact.
– Do not get the battery wet.

expressly approved in this manual could void your authority
to operate this 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 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.

– Consult the dealer or an experienced radio/TV technician for
help.
RF Exposure Statement
This transmitter must not be co-located or operated in
conjunction with any other antenna or transmitter used in
other systems. This device complies with FCC radiation
exposure limits set forth for an uncontrolled environment and
meets the FCC radio frequency (RF) Exposure Guidelines.
This equipment has very low levels of RF energy that is
deemed to comply without testing of specific absorption rate
(SAR).
For customers in Canada
IC statement
CAN ICES-3 (B)/NMB-3(B)
