Cause / Countermeasure • The protection circuit will be activated depending upon the temperature rise in the internal parts of the unit. Please switch off power at once, and re-apply the power after the body temperature has fallen sufficiently. • Please re-install AVR-990 in a place having good ventilation. • Please use speakers which have the specified impedance. • The protection circuit has been activated because the core wires of different speaker cables have touched each other or a core wire has slipped out of the terminal and is touching the AVR-990's rear panel. Unplug the power cord, then after twisting the core wires together tightly again, or effecting termination treatments etc, please reconnect once again. • The AVR-990 amplifier circuit has failed. Switch off the power and please contact the DENON service adviser. GRemote Control UnitH Symptom Cause / Countermeasure Set does not work • Batteries are worn. Replace with new batteries. properly when remote • Operate the remote control unit within a distance of about 7 m control unit operated. from the AVR-990 and at an angle of within 30°. • Remove the obstacle between the AVR-990 and the remote control unit. • Insert the batteries in the proper direction, checking the q and w marks. • The set's remote control sensor is exposed to strong light (direct sunlight, inverter type fluorescent bulb light, etc.). Move the set to a place in which the remote control sensor will not be exposed to strong light. • Make sure the remote control IDs of the main unit and remote control unit match. • Set the remote control unit's function button properly.
