CAUTION
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.
Be sure to move this switch only when this unit is in
standby mode.
Select the switch position (top or bottom) according to the
impedance of the speakers in your system.
