the outlet and refer servicing to qualified service  
personnel under the following conditions:  
a. When the power supply cord or plug is  
damaged.  
FCC & ICES INFORMATION  
(U.S.A. and Canadian Models Only)  
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.  
b. If liquid has been spilled or objects have fallen  
into the unit.  
c. If the unit has been exposed to water and/or  
inclement weather (rain, snow, etc.).  
d. If the unit does not operate normally by  
following the operating instructions. Adjust only  
those controls that are covered by the operating  
instructions, as an improper adjustment of other  
controls may result in damage and will often  
require extensive work by a qualified technician  
to restore the unit to its normal operation.  
e. If the unit has been dropped or the cabinet has  
been damaged.  
NOTE: This equipment has been tested and found to  
comply with the limits for a Class A digital device,  
pursuant to Part 15 of the FCC Rules and ICES-003 of  
Industry Canada. These limits are designed to provide  
reasonable protection against harmful interference  
when the equipment is operated in a commercial  
environment. This equipment generates, uses and  
radiates radio frequency energy, and if not installed  
and used in accordance with the instruction manual,  
may cause harmful interference to radio  
communications. Operation of this equipment in a  
residential area is likely to cause harmful interference,  
in which case the user will be required to correct the  
interference at his expense.  
Intentional or unintentional changes or modifications,  
not expressly approved by the party responsible for  
compliance, shall not be made. Any such changes  
or modifications could void the user’s authority to  
operate the equipment. If necessary, the user should  
consult the dealer or an experienced radio/television  
technician for corrective action.  
f. When the unit exhibits a distinct change in  
performance--this indicates a need for service.  
18. Replacement Parts - When replacement parts are  
required, be sure the service technician has used  
replacement parts specified by the manufacturer  
or have the same characteristics as the original  
part. Unauthorized substitutions may result in fire,  
electric shock, or other hazards.  
19. Safety Check - Upon completion of any service or  
repairs to this unit, ask the service technician to  
perform safety checks to determine that the unit is  
in proper operating condition.  
20. Coax Grounding - If an outside cable system is  
connected to the unit, be sure the cable system is  
grounded. U.S.A. models only--Section 810 of the  
National Electrical Code, ANSI/NFPA No.70,  
provides information with respect to proper  
grounding of the mount and supporting structure,  
grounding of the coax to a discharge unit, size of  
grounding conductors, location of discharge unit,  
connection to grounding electrodes, and  
requirements for the grounding electrode.  
21. Lightning - For added protection of this unit during  
a lightning storm, or when it is left unattended and  
unused for long periods of time, unplug it from the  
wall outlet and disconnect the cable system. This  
will prevent damage to the unit due to lightning  
and power line surges.  
WARNING: This is a Class A product. In a domestic  
environment, this product may cause radio  
interference, in which case, the user may be required  
to take adequate measures.  
The user may find the following booklet, prepared by  
the Federal Communications Commission, helpful:  
How to Identify and Resolve Radio-TV Interference  
Problems. This booklet is available from the U.S.  
Government Printing Office, Washington, DC 20402,

marche-arrêt ne fonctionnent que lorsque celui-ci  
est sur la position ON (marche). Le cordon  
d’alimentation est l’organe de coupure principal  
de l’alimentation pour tous les appareils.  
Power Disconnect. Units with or without ON-  
OFF switches have power supplied to the unit  
whenever the power cord is inserted into the  
power source; however, the unit is operational  
only when the ON-OFF switch is in the ON  
position. The power cord is the main power  
disconnect for all units.
