For Products That Transmit and 
Receive RF Energy:
FCC Regulations (USA Only)
FCC Information For Users
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. 
Radio and Television Interference
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 interference to radio 
or television reception, which can be determined by turning 
the equipment off and then on, the user is encouraged to try 
to correct the interference by one or more of the following 
measures: 
• Increase the separation between the equipment and
receiver. 
• Connect the equipment to a different outlet so that the
equipment and receiver are on different branch circuits. 
• Consult the dealer or an experienced radio/TV technician
for help.
NOTE: Changes or modifications not expressly approved 
by Harman could void the user’s authority to operate the 
equipment.
IC Statement and Warning (Canada Only)
This Class B digital apparatus complies with Canadian ICES-
003. Cet appareil numérique de la classe B est conforme à la 
norme NMB-003 du Canada.
For Canadian Model
This Class B digital apparatus complies with Canadian 
ICES-003.
Modèle pour les Canadien
Cet appareil numérique de la classe B est conforme à la 
norme NMB-003 du Canada.
For Products with Radio Receivers 
That Can Use an External Antenna:
CATV or Antenna Grounding
If an outside antenna or cable system is connected to this 
product, be certain that it is grounded so as to provide some 
protection against voltage surges and static charges. Section 
810 of the National Electrical Code, ANSI/NFPA No. 70-1984, 
provides information with respect to proper grounding of the 
mast and supporting structure, grounding of the lead-in wire 
to an antenna discharge unit, size of grounding conductors, 
location of antenna discharge unit, connection to grounding 
electrodes and requirements of the grounding electrode. 
Note to CATV System Installer:
This reminder is provided to call the CATV (cable TV) system 
installer’s attention to article 820-40 of the NEC, which 
provides guidelines for proper grounding and, in particular, 
specifies that the cable ground shall be connected to the 
grounding system of the building, as close to the point of 
cable entry as possible.
For CD/DVD/Blu-ray Disc
 Players:
Caution:
This product uses a laser system. To prevent direct exposure 
to the laser beam, do not open the cabinet enclosure or defeat 
any of the safety mechanisms provided for your protection. 
DO NOT STARE INTO THE LASER BEAM. To ensure proper use 
of this product, please read the owner’s manual carefully and 
retain it for future use. Should the unit require maintenance 
or repair, please contact your local Harman Kardon service 
center. Refer servicing to qualified personnel only. 
For Products That Include Batteries:
Instructions for Users on Removal and Disposal of 
Used Batteries.
CAUTION
Risk of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Alkaline batteries are considered nonhazardous. 
Rechargeable batteries (i.e., nickel cadmium, nickel metal-
hydride, lithium and lithium-ion) are considered hazardous 
household materials and may pose an unnecessary health 
and safety risk.
To remove the batteries from your equipment or remote 
control, reverse the procedure described for inserting 
batteries in the owner’s manual.
For products with a built-in battery that lasts for the lifetime of 
the product, removal may not be possible for the user. In this 
case, recycling or recovery centers handle the dismantling of 
the product and the removal of the battery. If, for any reason, it 
becomes necessary to replace such a battery, this procedure 
must be performed by authorized service centers.
Important Safety Instructions
CAUTION
RISK OF ELECTRIC SHOCK. DO NOT OPEN.
THE LIGHTNING FLASH WITH AN ARROWHEAD SYMBOL, 
WITHIN AN 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 PRODUCT.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC 
SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR 
MOISTURE.
-1
Each precaution in this manual should be followed during servicing.
Components identified with the IEC symbol
in the parts list are special significance to safety. When replacing a component identified with
, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the
parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before retuming the product to the customer.
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and
semiconductor "chip" components.
The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on
your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to
prevent electrostatic charge build-up or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges
sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement
ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the
chassis or circuit assembly into which the device will be installed.
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.
CAUTION :

SAFETY PRECAUTIONS
The following check should be performed for the continued
protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known earth ground (water
pipe, conduit, etc.) by connecting a leakage current tester
between the earth ground and all exposed metal parts of the
appliance (input/output terminals, screwheads, metal
overlays, control shaft, etc.). Plug the AC line cord of the
appliance directly into a 120V AC 60Hz outlet and turn the
AC power switch on. Any current measured must not exceed
o.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A
POTENTIAL SHOCK HAZARD AND MUST BE
CORRECTED BEFORE RETURNING THE APPLIANCE
TO THE CUSTOMER.
