1 Before Use
TOP PREVIOUS NEXT
Be sure to disconnect the mains cord before adjusting the voltage selector.
Use a minus(-)
screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the
area in which the unit will be used. (If the power supply in your area is 117V or 120V, set to the
“127V” position.)
Note that this unit will be seriously damaged if this setting is not made correctly. (There is no
voltage selector for some countries, the correct voltage is already set.)

2 Before Repair and Adjustment
TOP PREVIOUS NEXT
Disconnect AC power, discharge Power Supply Capacitors C520 and C540 through a 10Ω, 5W
resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may
destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
