Before Use ............ 1 Be sure to disconnect the mains cord belore adjusting the voltage selector. Use a minus (-) screwdriver to set the voltage selector (on the rear panel) to the vollage setting lor the area in which the unit wil! be used. (It Ihe power supply in your area is 117 V or 120 V, set to the "127 V" position.) Note that th is unit wil! be seriously damaged il th is setting is not made correctly. (There is no voltage selector lor some countries; the correct voltage is already set.) The configuration ol the AC outlet and AC power supply cord differs according to area.

Use trom an AC power souree ot high voltage, sueh as tor air eonditioners, is very dangerous. Be exlremely carelul nol 10 make aconnection 10 the electrical outlet lor a large air conditioner or central-heating unit which uses high voltage, because there is the possibility ol fire. 2. A DC power souree eannot be used. Be sure 10 check the power source carefully, especially on a ship or olher place where DC is used. · If water is spilled on the unit Be extremely careful if water is spilied on the unit, because a fire or serious electric shock might occur. Immediately disconneet the power cord plug, and consult wilh your dealer. · Place the unit wh ere it will be weil ventilated, and away from direct sunlighf - · Connection and removal of the power cord plug 1. Wet hands are dangerous. A dangerous electric shock may result if Ihe plug is touched by wet hands. 2. Don't pull the power eord. Always grasp the plug; never pull Ihe cord itself. Place th is unit at least 10 cm (4") away from wall surfaces, elc., and away from direct sunlight. Be careful that curtains and similar materials do not obstruct the ventilation holes. x · Keep the unit away from heaters, etc. Heat can damage the external surfaces as weil as internal circuits and components. x · Never attempt to repair or reconstruct this unit A serious eleclric shock might occur if Ih is unit is repaired, disassembied or reconstructed by unauthorized persons, or if Ihe internal parls are accidently touched. -x · For families with children Never permit children 10 put anything, especially metal, inside th is unit. A serious electric shock or malfunclion could occur il articles such as coins, needies, screwdrivers, elc. are inserled through the ventilation holes, etc. ol Ihis unit. · Avoid spray-type insecticides Insecticides might cause cracks or "cloudiness" in the cabinet and plastic parts ol this unit. The gas used in such sprays might, moreover, be ignited suddenly. [x~ · Never use alcohol or paint thinner ] x · Turn off after use II the unit is left lor a long lime with the power on, this will not only shorten its useful operation life. but mayalso cause other unexpected trouble.
