• To disconnect the power cord (mains lead), pull it

out the plug, not by the cord.

• Do not leave the unit in a location near a heat

source such as a radiator or airduct, or in a place
subject to direct sunlight, excessive dust,
mechanical vibration, or shock.

• Do not place the unit on surfaces (rugs, blankets,

etc.) or near materials (curtains, draperies) that
block the ventilation holes.

• Should any liquid or solid object fall into the unit,

unplug the unit and have it checked by qualified
personnel before operating it further.

• When the casing becomes soiled, clean it with a

soft cloth dampened with a mild detergent
solution. Never use abrasive cleaners or chemical
