How to Reset the Protection in a Denon DRA 685

by David Clair

The Denon DRA-685 AM/FM stereo receiver is equipped with a microprocessor that controls the various functions of the unit. If the microprocessor detects a potential problem, such as a short, it may go into protection mode. After the problem is resolved, you may need to reset the microprocessor in order to initialize and get it out of protection mode.

Step 1

Turn the Denon DRA-685 receiver off.

Step 2

Unplug the AC power cord from the wall electrical socket.

Step 3

Press and hold the "tune up" and "tune down" buttons.

Step 4

Plug the AC power cord into the electrical socket.

Release the "tune up" and "tune down" buttons after the entire display flashes in one-second intervals.

Tip

  • If the display does not flash in the final step, repeat the steps from the beginning.
