COMPLIANCE QUESTIONS ONLY:

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 

reg isters, 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 is provided for your safety. If the provided 

plug does not fit into your outlet, consult an electrician for 

replacement of the obsolete outlet.

Important Safety Instructions

MAgNETIC FIELD

CAUTION!  Do not locate sensitive high-gain equipment such as pre-

amplifiers 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 equip-

ment at the top.

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.

REgARDEZ CES SYMBOLES:

La triangle avec le sigle ‘’foudre’’ est employée pour alerter 

l’utilisateur au risque de décharge électrique. Le triangle avec 

un point d’exclamation est employée pour alerter l’utilisateur 

d’instruction importantes pour lors opérations de mainte nance.

ATENCION CON ESTOS SÍMBOLOS:

El triángulo con el símbolo de rayo eléctrico es usado para 

alertar al usuario de el riesgo de un choque eléctrico.
El triángulo con el signo de admiración es usado para alertar 

al usuario de instrucciones importantes de operación o man-

tenimiento.

WATCH FOR THESE SYMBOLS:

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 

complicance could void the user’s authority to operate the euqipment.

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 equip-

ment 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 com-

munications. 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 recep-

tion, 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.

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

par ticularly at plugs, convenience receptacles, and the point 

where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufac-

turer.

12. Use only with a 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.

13. Unplug this apparatus during lightning storms or when 

unused for long periods of time.

14. 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 nor mally, or has been dropped.

15. Use the mains plug to disconnect the apparatus from the 

mains.

16. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC 

SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR 

MOISTURE.

17. DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR 

SPASHING AND ENSURE THAT NO OBJECTS FILLED 

WITH LIQUIDS, SUCH AS VASES, ARE PLACED ON THE 

EQUIPMENT.

18. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL 

REMAIN READILY OPERABLE.
