Note that resetting the receiver will delete your radio presets and custom settings.

Make sure that the inputs and outputs of all compo- nents are connected properly.

Make sure that the correct input source is selected (page 21).

If the MUTING indicator is shown on the display, press the remote controller’s [MUTING] button to unmute the receiver (page 22).

If your turntable doesn’t have a phono preamp built- in, you must connect one between it and the receiver. If your turntable uses an MC cartridge, you must con- nect an MC head amp, or an MC transformer and a phono preamp.

Noise can be heard

Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so don’t do it.

An audio cable may be picking up interference. Try repositioning your cables.

The tone controls have no effect

If the DIRECT indicator or PURE AUDIO indicator lights up, the tone controls have no effect. Press the [DIRECT] button or [PURE AUDIO] button to turn the function off. The PURE AUDIO indicator will go off (page 23).

Power

Can’t turn on the receiver

Make sure that the power cord is plugged into the wall outlet properly.

Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it in again.

The STANDBY indicator is flashing

The amp protection circuit has been activated. Remove the power cord from the wall outlet immedi- ately. Disconnect all speaker cables and input sources, and leave the receiver with its power cord discon- nected for 1 hour. After that, reconnect the power cord and press the [STANDBY/ON] button again. If you can not resolve the problem, contact your Onkyo dealer.

Tuner

Reception is noisy, stereo FM reception suffers from hiss, or the FM STEREO indicator doesn’t appear

Relocate your antenna.

Move the receiver away from your TV or computer.

Listen to the station in mono (page 27).

When listening to an AM station, operating the remote controller may cause noise.

Passing cars and airplanes can cause interference.

Concrete walls weaken radio signals.

If nothing improves the reception, install an outdoor antenna.

Audio

There’s no sound or it’s very quiet

Make sure the speaker set A or B is on (page 21).

Make sure that all audio connecting plugs are pushed in all the way (pages 12 - 19).

Make sure that the polarity of the speaker cables is correct, and that the bare wire is in contact with metal part of each speaker terminal (page 12).

Make sure that the speaker cables are not shorting.
