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 

manufacturer.

12.  

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.

13.  Unplug this apparatus during lightning storms or 

when unused 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.   Do not expose this apparatus to dripping or 

splashing and ensure that no objects filled 
with liquids, such as vases, are placed on the 
apparatus. 

16.   To completely disconnect this apparatus from the 

AC Mains, disconnect the power supply cord plug 
from the AC receptacle. 

17.   The mains plug of the power supply cord shall 

remain readily operable. 

18.  Do not expose batteries to excessive heat such as 

sunshine, fire or the like.

The lightning flash with 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 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 product.

WARNING: To reduce the risk of fire or electric 
shock, do not expose this apparatus to rain or 
moisture.

19.   When replacement parts are required, be sure the 

service technician has used replacement parts 
specified by the manufacturer or have the same 
characteristics as the original part. Unauthorised 
substitutions may result in fire, electric shock or 
other hazards.

20.   For continued protection against fire hazard, use 

fuses only of the correct type and rating. Mains 
fuses are located inside the appliance as well as 
on its back panel. Replacement of the internal fuse 
should be entrusted to an authorised operative. 
User-replaceable fuse types are shown in the 
specification.

21.   Isolation of the appliance from the power supply is 

by means of removal of the power cord from the 
rear of the appliance or removal of the power cord 
from the wall power outlet. Either the wall outlet 
or the rear of the appliance must remain freely 
accessible at all times while the apparatus is in 
use.

22.   This product should be operated only from the 

type of power source indicated by the marking 
adjacent to the power cord entry. If you are not 
sure of the type of power supply to your home, 
consult your product dealer or local power 
company.

23.   Do not overload wall outlets, extension cords or 

integral convenience receptacles, as this can result 
in a risk of fire or electric shock.

24.   Magnetic fields – The product creates a stray 

static magnetic field. Do not place any object 
that may be damaged by this magnetic field 
(eg cathode ray tube televisions or computer 
monitors, audio and video tapes and swipe cards) 
within 0.5m (2 feet) of the appliance. The appliance 
may cause distortion of cathode ray tube images 
beyond this distance. LCD and Plasma screens 
are not affected.
