Error: The message PROTECT or UNPLUG shows in the display.
Follow this procedure to troubleshoot when a PROTECT or UNPLUG error is displayed.
IMPORTANT: The top of the receiver must have proper ventilation to keep from over heating.
- Reduce the volume level.
NOTE: If the receiver is played at the maximum volume level it may enter the PROTECT mode. Maximum volume listening will cause the receiver to run hot and drain the output capacitors.
- If both the A and B speakers are being powered by the receiver at the same time, turn off the surround sound option.
- If protect occurs only when using a DVD player, the sampling frequency may be set too high.
NOTE: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the user manual for specific information.
- Ensure the speaker wiring is not damaged and is properley connected to the back of the receiver and speakers.
- If the issue is still unresolved after completing all of the troubleshooting steps, service may be required.
