Please 

always 

follow these instructions to help ensure 

against injury to yourself and 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. 

 
4) 

Follow

 all installation, operating and use 

instructions. 

 
5)  

Unplug

 the apparatus from the AC power 

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

 
6) 

Do not use

 accessories or attachments not 

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

 
7) 

Do not operate

 this apparatus in high 

humidity areas or expose it to water or 
moisture. 

 
8) 

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. 

 
9) 

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.  

 

 10) 

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. 

 

11) 

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. If 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. 

 
12) 

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. 

 
13) 

Do not overload 

wall outlets or extension 

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

 
14) 

Unplug

 this apparatus during lightning storms 

or when unused for long periods of time. 

 
15) 

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. 

 
16) 

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.
