Connecting the AC power cord
Before connecting the AC power cord of this receiver to a
wall outlet:
• Connect the speaker system to the receiver (see page
15).
• Turn the MASTER VOLUME control to the leftmost
position (0).
Connect the AC power cord(s) of your audio/video
components to a wall outlet.
If you connect other audio/video components to the AC
OUTLET(s) on the receiver, the receiver will supply power
to the connected component(s), allowing you to turn the
whole system on or off when you turn the receiver on/off.
Caution
Make sure that the total power consumption of the component(s)
connected to the receiver's AC OUTLET(s) does not exceed the
wattage stated on the rear panel. Do not connect high-wattage
electrical home appliances such as electric irons, fans, or TVs to
this outlet.
Note
If the AC power cord is disconnected for about two weeks, the
receiver's entire memory will be cleaned and the demonstration
will start.
