Troubleshooting

If you have any trouble using the receiver, look for a solution in this section.

If you can’t resolve the issue yourself, try resetting the receiver before contacting your Onkyo dealer.

To reset the receiver to its factory defaults, turn it on and, while holding down the [TUNING MODE] button, press the [ON/STANDBY] button.

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

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

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

Audio

There’s no sound or it’s very quiet

•Make sure the speaker set A or B is on (page 19).

•Make sure that all audio connecting plugs are pushed in all the way (page 14-17).

•Make sure that the polarity of the speaker cables is correct, and that the bare wire is in contact with the metal part of each speaker terminal (page 10).

•While a pair of headphones is connected to the PHONES jack, no sound is output from the speakers. (page 19)

Noise can be heard

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the

audio performance; do not bundle audio cables together with power cords or speaker cables.

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 23).

•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.

Remote Controller

The remote controller doesn’t work

•After inserting or replacing the batteries, press the remote controller’s [MAIN] or [Zone 2] button before you start performing the desired operation (page 9).

•Make sure that the batteries are installed with the correct polarity (page 6).
