TROUBLESHOOTING

The SDP-40 does not power on.

1.Make sure the rear panel power switch is set to the(“on”) position.

2.Attempt to deactivate standby mode with both the front panel and remote control standby buttons.

3.Examine the power cord to ensure a solid connection between the AC input connector and the wall outlet.

4.Examine the electrical circuit and breaker.

The remote control does not work.

1.Eliminate obstructions between the remote control and the front panel IR receiver. When the SDP-40 is not using the rear panel IR IN connector, the remote control must be in line-of- sight with the front panel IR receiver for proper operation. The remote control might also become unreliable if strong sunlight or fluorescent light is shining on the IR receiver.

2.Make sure the remote control batteries are correctly inserted with the proper polarity.

3.Replace the remote control batteries. When the batteries are low on power, the remote control enters a low-voltage condition that prevents it from operating the SDP-40.

The SDP-40 is powered on, but there is no audio.

1.Examine the audio cables to ensure a solid connection between the SDP-40 and all associated power amplifiers.

2.Make sure volume is set to an audible level. Volume level can be increased with the front panel volume knob or the remote control VOL + and – buttons.

3.Make sure audio has not been muted. The message “MUTE ON” or “FULL MUTE ON” will appear on the on-screen and front panel displays when audio has been muted. To deactivate mute, press the Mute button or adjust volume level.

4.Check the INPUT SETUP menu DIGITAL IN and ANALOG IN parameters to make sure the appropriate audio connector is assigned to the selected input.

5.Make sure the SDP-40 is receiving an audio signal. To do this, follow the instructions that begin on page 2-20 to open the status menu for the current input source.

6.Make sure all associated power amplifiers are powered on.
