IMPEDANCE SELECTOR switch
Do not change the setting of the IMPEDANCE 
SELECTOR switch when the unit power is switched on, 
as doing so may damage the unit.
If this unit fails to turn on when STANDBY/ON is pressed 
on either the front panel or remote control, the 
IMPEDANCE SELECTOR switch may not be fully slid to 
either position. If this is the case, slide the switch all the 
way to either position when this unit is in standby mode.
Select the switch position (left or right) according to the 
impedance of the speakers in your system.
