Important Safety Instructions

 /

 

안전을  위한  주의  사항

 

 

8. Polarization 

If the appliance is 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 to replace your 

obsolete outlet. Do not defeat the safety purpose of the 

polarized plug. 

9. Grounding 

If the appliance is equipped with a 3-wire grounding-type 

plug, a plug having a third (grounding) pin, this plug will 

only fit into a grounding-type power outlet. This is safety 

feature. If you are unable to insert the plug into the outlet, 

contact your electrician to replace your obsolete outlet. Do 

not defeat the safety purpose of the grounding-type plug. 

10. Power Cord Protection 

Power supply cords 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 cords at plugs, 

convenience receptacles, and the point where they exit from 

the appliance. 

11. Damage Requiring Service 

Unplug this appliance from the wall outlet and refer 

servicing to qualified service personnel under the following 

conditions: 

a. When the power-supply cord or plug is damaged. 

b. If liquid has been spilled, or objects have fallen into the   

appliance. 

c. If the appliance has been exposed to rain or water. 

d. If the appliance does not operate normally by following   

the operating Instructions.   

Adjust only those controls that are covered by the 

operating instructions as an improper adjustment of other 

controls may result in damage and will often require   

extensive work by a qualified technician to restore the 

    appliance to its normal operation. 

e. If the appliance has been dropped or the cabinet has been 

 damaged. 

f. When the appliance exhibits a distinct change in   

    performance - this indicates a need for service. 

12. Servicing 

Do not attempt to service this appliance yourself as opening 

or removing covers may expose you to dangerous voltage or 

other hazards. Refer all servicing to qualified service 

personnel.
