(Reter to page 4.) |
|
The configuration ol the AC outlet and AC power supply cord differs according to area.
Before Use
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 this unit wil! be seriously damaged il this setting is not made correctly. (There is no voltage selector lor some countries; the correct voltage is already set.)

Suggestions for Safety
• Use a standard electrical AC wall outlet
1.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.
-• Connectionplug and removal of the power cord
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.
x
•Never attempt to repair or reconstruct this unit
A serious eleclric shock might occur if Ihis 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.
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.
x 
•Place the unit where it will be weil ventilated, and away from direct sunlighf
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.
• 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
These and similar chemicals should never be used, because they may damage the finish.
[~x_~__·,~~~_.~~~]
• If trouble occurs
If, during operation, the sound is interrupted or indicators no longer illuminate, or if abnormal odor or smoke is detected, immediately disconneet the power cord plug, and contact your dealer or an Authorized Service Center.

Speaker impedance selector
Set to the position corresponding to the impedance of the speaker systems being used.
If a speaker system with an impedance value outside these ranges is connected, low output, protection circuit aclivation or amplifier damage may occur.

For speaker impedance of 4~611. 8~1611(........):
For speaker impedance of a~1611.

1)If the impedance of both systems is 16 ohms, set the speaker impedance selector to "16n".
2)If the impedance of both systems is a ohms, or one is aohms and the other is 16 ohms, set the speaker impedance seleclor
to "a11".

Protection Circuitry
The protection circuilry may have operaled if eilher of the
following conditions |
is noliced: |
-No sound is heard |
when the power is turned on. |
-Sound stops during a performance.
The funclion of this circuitry is to prevent circuilry damage if, for example, the positive and negative speaker connection wires are "shorted", or il speaker systems with an impedance less than the indicated rated impedance ol the amplifier are used.
If th is occurs, follow the procedure outlined below:
1.Turn olf the power.
2.Determine Ihe cause of the problem and correct it
3.Turn on the power once again.
Note:
When Ihe pralection circuilry functions, Ihe unit will not operate unless the power is lirsl turned olf and then on again.
