CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER. NO USER-SERVICEABLE
IMPORTANT SAFETY INFORMATION
The lightning flash with arrowhead symbol, within equilateral triangle, is intended to alert the user
to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be
of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the
literature accompanying the appliance.accordance with manufacturers’ instructions.
WARNING: TO AVOID FIRE OR ELECTRIC
SHOCK HAZARD, DO NOT EXPOSE THIS
APPARATUS TO WATER, RAIN OR MOISTURE.
NOTE — This apparatus does not exceed the Class A/Class B (whichever is applicable) limits for radio noise emissions
from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications.
.
ATTENTION — Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant las limites applicables
aux appareils numériques de class A/de class B (selon le cas) prescrites dans le réglement sur le brouillage radioélec-
trique édicté par les ministere des communications du Canada.
These limits are designed to provide reasonable protection against harmful interference in a commercial/residential
installation respectively. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful interference to radio communications. There is no
guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or
television equipment reception, which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by any combination of the following measures: (1) Relocate or reorient the receiving
antenna (2) Increase the separation between the equipment and the receiver (3) Plug the equipment into an outlet on a
circuit different from that to which the receiver is connected (4) Consult your dealer or experienced radio/television
technician for additional assistance
CAUTION — Changes or modifications to this equipment not expressly approved by the party responsible for compliance
could void the user’s authority to operate this equipment.
