SAFETY INSTRUCTIONS 

 

 
 

Please always follow these instructions to help ensure against injury to yourself  

and/or damage to the system 

 
 
1) 

Read all safety and operating instructions 

before you operate the apparatus. 
 
2)  

Retain all safety and operating instructions 

for future reference. 
 
3) 

Heed all warnings on the apparatus and in 

the safety and operating instructions and follow all 
instructions for installation, operating and use. 
 
4)  

Unplug the apparatus from the AC power 

outlet before cleaning. Use only a damp cloth for 
cleaning the exterior of the apparatus. 
 
5) 

Do not use accessories or attachments not 

recommended by the manufacturer, as they may 
cause hazards and void the warranty. 
 
6) 

Do not operate this apparatus in high 

humidity areas or expose it to water or moisture. 
 
7) 

Do not place the apparatus on an unstable 

cart, stand, tripod, bracket or table. The apparatus 
may fall, causing serious personal injury and 
damage to the apparatus. 
 
8) 

Do not block or cover any openings in the 

apparatus. These are provided for ventilation and 
protection from overheating. Never place the 
apparatus near any heat sources such as 
radiators, heat registers, stoves, or other 
apparatus (including amplifiers) that produce heat. 
Do not place the apparatus in an enclosure such 
as a cabinet without proper ventilation.  
 
9) 

Operate the apparatus using only the type 

of power source indicated on the marking label. 
Unplug the apparatus’ power cord by gripping the 
power plug, not the cord. 
 

10) 

Insert the plug properly. Do not defeat the 

safety purpose of the polarized or grounding type 
plug. A polarized AC line plug has two blades with 
one wider than the other. This plug will fit into the 
power outlet only one way. This is a safety 
feature. f you are unable to insert the plug fully 
into the outlet, try reversing the plug. If the plug 
still fails to fit, contact an electrician to replace the 
obsolete outlet. 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 to replace the 
obsolete outlet. 
 
11) 

Route power supply cords so that they are 

not likely to be walked on or pinched by items 
placed upon or against them. Pay particular 
attention to cords at plugs, convenience 
receptacles, and the point where they exit from the 
apparatus. 
 
12) 

Do not overload wall outlets or extension 

cords, as this can result in a risk of fire or electrical 
shock. 
 
13) 

Unplug this apparatus during lightning 

storms or when unused for long periods of time. 
 
14) 

Never insert objects of any kind into the 

apparatus through openings, as the objects may 
touch dangerous voltage points or short out parts. 
This could cause fire or electrical shock. 
 
15) 

Refer all servicing to qualified service 

personnel. Servicing is required when the 
apparatus has been damaged in any way, such as 
when the 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.
