If this happens, unplug thepower cord, wait for the set to cool off andimprove ventilation around the unit. Also checkthe wiring of the input cables and the speakercables. After doing this, plug the power cordback in and turn the unit’s power back on.If the protection circuit is activated again eventhough there are no problems with the wiring orthe ventilation around the unit, switch off thepower and contact a DENON service center.NOTE:When making connections, take care thatnone of the individual conductors of thespeaker cable come in contact with adjacentterminals, with other speaker cableconductors, or with the rear panel andscrews.NEVER touch the speaker terminals whenthe power is on. Doing so could result inelectric shocks.1. Loosen by turningcounterclockwise.Either tightly twist or terminate the corewires.2. Insert the cable.3.
