FCC COMPLIANCE NOTICE

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.

CAUTION: Changes or modifications not expressly approved by 

the party responsible for compliance could void the user’s author-

ity to operate the 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 instal-

lation. 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. 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.
•  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.

WARNING: 

•  Apparatet må tilkoples jordet stikkontakt. 
•  Apparaten skall anslutas till jordat uttag. 
•  Laite on liitettävä suojakoskettimilla varustettuun pistorasiaan. 
•  Apparatet skal tilsluttes jordet stikkontakt. 

1.  Read these instructions.
2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions.
5.  Do not use this apparatus near water.
6.  Clean only with a dry cloth.
7.  Do not block any ventilation openings. Install in accordance with the 

manufacturer’s instructions.

8.  Do not install near any heat sources such as radiators, heat registers, stoves, or 

other apparatus (including amplifiers) that produce heat.

9.  Do not defeat the safety purpose of the polarized or grounding-type plug. A 

polarized plug has two blades with one wider than the other. A grounding-type 

plug has two blades and a third grounding prong. The wide blade or the third 

prong are provided for your safety. If the provided plug does not fit into your 

outlet, consult an electrician for replacement of the obsolete outlet.

10.  Protect the power cord from being walked on or pinched, particularly at plugs, 

convenience receptacles, and the point where they exit from the apparatus.

11.  Use only with the cart, stand, tripod, bracket, or table specified by the 

manufacturer, or sold with the apparatus. When a cart is used, use caution when 

moving the cart/apparatus combination to avoid injury from tip-over.

12.  Unplug this apparatus during lightning storms or when unused for long periods 

of time.

13.  Refer all servicing to qualified service personnel. Servicing is required when the 

apparatus has been damaged in any way, such as power-supply cord or plug is 

damaged, liquid has been spilled or objects have fallen into the apparatus, the 

apparatus has been exposed to rain or moisture, does not operate normally, or has 

been dropped.

14.  Use the mains plug to disconnect the apparatus from the mains.
15.  WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT 

EXPOSE THIS APPARATUS TO RAIN OR MOISTURE.

16.  “DO NOT EXPOSE THIS APPARATUS TO DRIPPING OR SPLASHING AND 

ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, ARE 

PLACED ON THE APPARATUS” AND “NE PAS EXPOSER CET APPAREIL À DES 

ÉCLABOUSSURES OU GOUTTELETTES D’UN LIQUIDE. AUCUN OBJET REMPLIE 

DE LIQUIDE COMME PAR EXEMPLE UN VASE NE DOIT ÊTRE PLACÉ SUR 

L’APPAREIL”.

17.  THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN READILY 

ACCESSIBLE. LA PRISE DU RÉSEAU D’ALIMENTATION DOIT DEMEURER 

AISÉMENT ACCESSIBLE.

TO PREVENT ELECTRIC SHOCK DO NOT REMOVE TOP COVER. NO USER 

SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE 

PERSONNEL.
TO COMPLETELY DISCONNECT THIS APPARATUS FROM THE AC MAINS, 

DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE AC RECEPTACLE. 

POUR DÉCONNECTER COMPLÈTEMENT L’APPAREIL DU RÉSEAU D’ALIMENTATION, 

DÉCONNECTER LE CORDON D’ALIMENTATION DE LA PRISE MURALE.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such 

as preamplifiers or tape decks directly above or below the unit. 

Because this amplifier has a high power density, it has a strong 

magnetic field which can induce hum into unshielded devices 

that are located nearby. The field is strongest just above and 

below the unit.

If an equipment rack is used, we recommend locating the 

amplifier(s) in the bottom of the rack and the preamplifier or 

other sensitive equipment at the top.

WATCH FOR THESE SYMBOLS:

The lightning bolt triangle is used to alert the user to 

the risk of electric shock.
The exclamation point triangle is used to alert the user 

to important operating or maintenance instructions.

IMPORTANT

Class 2 output wiring permitted.
