CAUTION

: to reduce the risk of electric shock, do not 

remove  cover  (or  back).    No  user-serviceable  parts 

inside.  Refer servicing to qualified service personnel.

The lightning flash with arrowhead symbol, 

within  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  magnitude  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 appliance.

Instructions

Before  installing  or  operating  the  equipment,  read  all 

safety instructions, warnings and operating instructions.  

Heed  all  warnings.    Follow  all  instructions.    Keep  all 

safety,  installing  and  operating  instructions  for  future 

reference.

Installing and operating location

Do not use this apparatus near water.  Do not expose 

this  apparatus  to  drips  or  splashes.    Do  not  place 

any  objects  filled  with  liquids,  such  as  vases,  on  the 

apparatus.

Do not install near any heat sources such as radiators, 

heat  registers,  stoves,  or  other  apparatus  (including 

amplifiers) that produce heat.  No naked flames, such 

as lighted candles, should be placed on the apparatus.

Do not install the apparatus in a confined space such as 

a book case or similar unit.  Do not block any ventilation 

openings.  

Ensure that foreign objects and liquids cannot get into 

the equipment.

Install in accordance with the manufacturer’s instructions. 

Only  use  attachments/accessories  specified  by  the 

manufacturer.

Use  only  with  the  cart,  stand,  tripod,  bracket  or 

table  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.

The apparatus should be located close enough to the 

AC outlet so that you can easily grasp the power cord 

plug at any time.

The  mains  plug,  the  appliance  coupler  or  the  mains 

switch is used as the disconnect device.  Either device 

shall  remain  readily  operable  when  the  apparatus  is 

installed or used.

Power source and grounding

This product should be operated only from the power 

source indicated on the apparatus or in the operating 

instructions.  If you are not sure of the type of power 

supply  to  your  home,  consult  your  product  dealer  or 

local power company.

Do  not  defeat  the  safety  purpose  of  the  polarised  or 

grounding-type plug.  A polarised 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 is provided for your safety.  If 

the provided plug does not fit into your outlet, consult an 

electrician for replacement of the obsolete outlet.

Connect Class I construction apparatus to an AC outlet 

with a protective grounding connection. 

Do not overload wall outlets, extension cords or integral 

convenience receptacles, as this can result in a risk of 

fire or electric shock.

Protect the power cord from being walked on or pinched, 

particularly at plugs, convenience receptacles and the 

point where they exit form the apparatus.

Unplug this apparatus during lightning storms or when 

unused for long periods of time.

Batteries (battery pack or batteries installed) should not 

be exposed to excessive heat such as sunshine, fire or 

the like.  Never dispose of batteries in a fire as they may 

explode and cause injury.

CAUTION

: Danger of explosion if battery is incorrectly 

replaced.  Replace  only  with  the  same  or  equivalent 

type.
