IMPORTANT SAFETY INSTRUCTIONS                                                                             

 
Caution: Read This Before Operating Your Unit. 
 

1. 

READ  AND  FOLLOW  INSTRUCTIONS: 

All  the  safety  and  operation  instructions  should  be  read  before  the  product  is 

operated. Follow all operation instructions within this manual. 

 
2. 

RETAIN INSTRUCTIONS: 

The safety and operation instructions should be retained for future reference. 

 
3. 

HEED WARNINGS:

 Comply with all warnings on the product and in the operation instructions. 

 
4. 

CLEANING: 

Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a 

damp cloth for cleaning. 

 
5. 

GROUNDING  or  POLARIZATION: 

This  product  may  be  equipped  with  a  polarized  alternating  current  line  plug  (a  plug 

having one blade 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 should still fail to fit, contact your electrician 
since it is likely you have an out of sate wall socket. Never force the plug into the socket. 

 
6. 

OVERLOADING:

 Do not overload wall outlets or extension cords as this can result in the risk of 

fire or electric shock. Overloaded AC outlets, extension cords, frayed power cables, damaged 
or cracked wire insulation, and broken plugs are dangerous. They may result in electric shock 
or fire  hazard.  Periodically  examine the  power  cable  - if its appearance  indicates  damage  or 
deteriorated receptacles have it replaced by your service technician. 

 
7. 

POWER SOURCES: 

This product should be operated only from the type of power source indicated on the rear panel label. If 

you are not sure of the type of power supply to your home, consult your product dealer or local power company. For products 
intend to be operated from battery power, or other sources, refer to the operation instructions. 

 
8. 

ACCESSORIES:

 Do not place this product on an unstable surface or support. The product may fall, 

causing serious injury to a child or adult as well as serious damage to the product. Any mounting of 
the  product  should  follow  the  manufacture

s  instructions  and  use  a  mounting  accessory 

recommended  by  the  manufacturer.  A  product  and  cart  combination  should  be  moved  with  care. 
Quick stops, excessive force, and uneven surfaces may cause the product and cart combination to 
overturn. 

 
9. 

OUTDOOR  ANTENNA  GROUNDING:

  If  an  outside  antenna  or  cable  system  is  connected  to  the 

product,  be  sure  the  antenna  or  cable  system  is  grounded so  as to provide  some  protection  against voltage  surges  and 
built-up  static  charges.  The  example  below  is  for  reference  only.  Correct  grounding  should  always  be  installed  by  an 
electrician.

10. 

POWER-CORD  PROTECTION: 

The  power  supply  cables  should  be routed  so that they are  not likely  to  be  walked  on  or 

pinched by items placed upon or against them, paying particular attention to cables at plugs and the point where they exit 
from the product. 

 
11.

Do not use unauthorized attachments as they may cause faults with the unit.

often require extensive work by a qualified technician to restore the product to its normal operation). 

f) 

If the product has been dropped or damaged in any way.
