Symbols and Descriptions

Read the instructions.

 All the safety and operating instruc-

tions should be read before the product is used.

Follow instructions.

 All operating instructions and other 

guidelines should be observed.

Keep the instructions. 

The safety and operating instructions 

should be kept handy for future reference.

Observe all warnings.

 The warnings provided on the product 

and in the operating instructions should be heeded for the 

assurance of safety and performance.

Water and moisture: 

The product should not be used near 

water, for example near a bathtub, washbowl, kitchen sink, 

laundry tub, in a wet basement, near a swimming pool, etc.

Mounting in a wall or ceiling: 

The product should be in-

stalled strictly in accordance with the instructions, guidelines 

and recommendations provided by Proficient.

Ventilation: 

The product should be situated in such a place 

that its proper ventilation and performance are not hindered. 

For example, the product should not be situated on a bed, 

sofa, rug or similar surface that may block the ventilation 

openings; or placed in a built-in installation, such as a book-

case or cabinet that may impede the flow of air through the 

ventilation openings.

Heat:

 The product should be situated away from heat sources 

such as radiators, stoves, or other appliances that produce 

heat.

Power source: 

The product should be connected to a power 

supply only of the type described in the operating instructions 

or as marked on the product.

Power-cord protection:

 Power-supply cords should be routed 

so that they won’t be walked on or pinched by items placed 

upon or against them. Pay special attention to cords at their 

plug ends and the points where they exit from the products.

Cleaning:

 The amplifier should be kept clean and relatively 

dust-free to ensure cool, reliable operation. Wipe it occasion-

ally with a dry, lint-free cloth, using particular care around the 

back-panel connections.

Periods of non-use: 

The power cord should be unplugged 

from the outlet if the amplifier is to go unused for a long pe-

riod of time.

Entry by objects/liquids: 

Care should be taken so that small 

objects and liquids are not allowed to enter the product. The 

entry of foreign substances could result in equipment mal-

function and pose a risk of fire.

Carts and stands:

 The product should be used only with a cart 

or stand that is recommended by Proficient.

Damage requiring service:

 The amplifier should be serviced 

by qualified service personnel when:

   a. 

The power-supply cord or plug has been damaged.

   b.

 Objects have fallen onto the product or liquid has been     

        spilled into it.

   c.

 The product has been exposed to rain.

   d. 

The product does not appear to be working normally or is      

       showing significantly less performance.

   e.

 The product has been dropped, or the cabinet has been    

        damaged.

Service:

 The end user should not attempt to service the prod-

uct. All repairs should be handled by a qualified technician.

Grounding and polarity: 

Precautions should be taken so that 

the amplifier’s grounding or polarization is not removed.

APPLICABLE FOR USA, CANADA OR WHERE APPROVED 

FOR USE.

CAUTION:

 TO PREVENT ELECTRIC SHOCK, MATCH

THE WIDE BLADE OF THE PLUG WITH THE WIDE SLOT IN THE 

OUTLET, AND THEN INSERT THE PLUG FULLY.

ATTENTION: 

POUR EVITER LES CHOCS ELECTRIQUES, 

INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA 

BORNE CORRESPONDANTE DE LA PRISE ET POUSSER JUSQU 

AU FOND. 

A lightning bolt with an arrowhead in a tri-

angle, whether located on the product or in 

the manual, calls attention to the presence of 

non-insulated “dangerous voltage” within the 

product enclosure. Direct or indirect bodily 

contact with such voltage poses a risk of electric 

shock, injury or death.

An exclamation point within a triangle, either on 

the product or in the manual, calls attention to 

important operating and maintenance (servic-

ing) instructions.

CAUTION: 

Do not remove the cover or rear panel from the 

amplifier. There are no user-serviceable parts inside. Instead, 

refer all repairs to a qualified technician. Observance of this 

precaution will dramatically reduce the risk of exposure to 

high voltages.
