Introduction

Important safety instructions

  The lightning flash with an arrowhead symbol within an 

equilateral triangle, is intended to alert the user to the 
presence of uninsulated “dangerous voltage” within 
the product’s enclosure that may be of sufficient mag-
nitude to constitute a risk of electric shock to persons.

  The exclamation point within an equilateral triangle is 

intended to alert the user to the presence of important 
operating and maintenance (servicing) instructions in 
the literature accompanying the product.

  1. Read these instructions.
  2. Keep these instructions.
  3. Heed all warnings.
  4. Follow all instructions.
  5. Do not use this apparatus near water.
  6. Clean only with dry cloth.
  7. Do  not  block  any  ventilation  openings.  Install  in  accor-

dance with the manufacturer’s instructions.

  8. Do  not  install  near  any  heat  sources  such  as  radiators, 

heat registers, stoves, or other apparatus (including ampli-
fiers) that produce heat.

  9. Do  not  defeat  the  safety  purpose  of  the  polarized  or 

grounding-type plug. A polarized plug has two blades with 
one wider than the other. 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 for 
replacement of the obsolete outlet.

 10. Protect the power cord from being walked on or pinched 

particularly  at  plugs,  convenience  receptacles,  and  the 
point where they exit from the apparatus.

 11. Only use attachments/accessories specified by the manu-

facturer.

 12. Use only with the cart, stand, tripod, bracket, or ta-

ble specified by the manufacturer, or sold with the 
apparatus. When a cart is used use caution when moving 

the  cart/apparatus  combination  to  avoid  injury  from  tip-
over.

 13. Unplug this apparatus during lightning storms or when un-

used for long periods of time.

 14. Refer all servicing to qualified service personnel. Servicing 

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

 15. WARNING: To reduce the risk of fire or electric shock, this 

apparatus should not be exposed to rain or moisture and 
objects  filled  with  liquids,  such  as  vases,  should  not  be 
placed on this apparatus.

 16. To completely disconnect this equipment from the mains, 

disconnect the power supply cord plug from the recepta-
cle.

 17. The  mains  plug  of  the  power  supply  cord  shall  remain 

readily operable.

 18. Danger:  To  reduce  the  risk  of  electric  shock,  do  not  re-

move the back panel and do not expose the apparatus to 
rain or moisture. No user serviceable parts inside. Refer 
servicing to qualified personnel.
