•Protector circuit

The DRA-F100 is equipped with a high speed protector circuit.

This circuit protects internal parts from being damaged by strong currents generated in the set should the set be operated when the speaker terminals are incompletely connected or short-circuited.

If this protector circuit is activated, a relay sound is produced, the output to the speakers is interrupted, and the function and power LEDs flash to indicate that there is a problem. If this should happen, unplug the power cord, check the speaker connections, then plug in the power cord and turn the power back on. After several seconds, a relay sound is heard and the set starts operating properly.

•The set may not operate properly due to such external influences as lightning or static electricity. If this happens, either turn off the power with the receiver’s SYSTEM power operation switch or unplug the power cord, wait approximately 5 seconds, then plug the power cord back in.
