Important Safety Instructions 

 
Before using your Stewart Audio Inc. Power Amplifier, please read this 

Owner’s Manual 

carefully to ensure optimum trouble-free perfor-

mance. 
 

WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT EX-
POSE THIS AMPLIFIER TO RAIN OR MOISTURE. DANGEROUS HIGH 
VOLTAGES ARE PRESENT INSIDE THE ENCLOSURE. DO NOT OPEN THE 
CABINET. REFER  SERVICING TO QUALIFIED PERSONNEL ONLY.

    

 
 
 
 
 
 
 
 
 
 

 
 

The lighting bolt within arrowhead symbol, within an 
equilateral triangle, is intended to alert the user to the 
presence of un-insulated “dangerous voltage” within 
the product’s enclosure that may be of sufficient mag-
nitude to constitute a risk of electrical shock to person. 
 
The exclamation point within an equilateral triangle, is 
intended to alert the user to the presence of important 
operating and maintenance (servicing) instruction in the 
literature accompanying the appliance. 
 
 

Important Safety Instruction – Please Read Prior to Product  
Installation. 

 

1.  Installation should be performed by a trained and licensed professional to 

insure safe and lasting operation. 

 

2. 

All of the safety and operating instructions should be read before the am-
plifier is installed or operated. Retain these instructions for future refer-
ence. All instructions should be followed; all warnings on the amplifier 
and in the operating instructions should be adhered to. 

 

3.  The amplifier should be situated so that its location and position does not 

interfere with its proper ventilation. For example, the amplifier must not 
be placed on a rug, bed, sofa or similar surface that impedes airflow 
across the chassis. Airflow around the unit should be unobstructed. 

 
4.  This amplifier should not be used near water, for example, near a bathtub, 

in a wet basement, near a swimming pool, etc. This amplifier is  intended 
to be operated in a controlled indoor environment. 

 
5.  Do not place the amplifier near heat sources such as radiators, heat regis-

ters, stoves, or other appliances that produce heat. 

 
6.  The amplifier’s power supply should only be connected to 120 VAC, 60 

Hz power source. Do not defeat the ground or polarization of the power 
plug. 

 
7.  Route power cord and other cables so that they are not likely to be 

walked on, tripped over or stressed. Pay particular attention to condition 
of cords and cables at plugs and at the point where they exit the amplifi-
er. To prevent risk of fire or injury, damaged cords and cables should be 
replaced immediately. 

 
8.  Clean the amplifier with a clean, damp cloth. Do not use solvents or abra-

sive cleaners. Never pour any liquid on the amplifier. 

 
9.  When left unused for a long period of time, the power cord should be 

unplugged from the outlet. 

 
10.  Damaged Amplifiers requiring service should be repaired by a qualified 

service technician when: 

 

a. 

The power cord or AC plug has been damaged. 

b.  Objects have fallen, or liquid has spilled into the unit. 
c. 

The amplifier has been exposed to rain or other moisture. 

d.  The amplifier does not appear to operate normally or exhibits 

a marked change in performance. 

e.  The amplifier has been dropped or the enclosure  
 damaged. 

 

11. The user should not attempt to service the amplifier beyond that de-

scribed in the operating instructions. All other servicing should be referred 
to qualified service personnel.
