2 CAUTIONS ON INSTALLATION Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV. If this happens, take the following steps: • Install this unit as far as possible from the tuner or TV. • Set the antenna wires from the tuner or TV away from this unit's power cord and input/output connection cords. • Noise or disturbance tends to occur particularly when using indoor antennas or 300 Ω/ohms feeder wires. We recommend using outdoor antennas and 75 Ω/ohms coaxial cables. For heat dispersal, leave at least 0.3 ft (10 cm) of space between the top, back and sides of this unit and the wall or other components. ENGLISH 0.3 ft (10 cm) or more 0.3 ft (10 cm) or more wall 3 CAUTIONS ON HANDLING • Switching the input function when input jacks are not connected A clicking noise may be produced if the input function is switched when nothing is connected to the input jacks. If this happens, either turn down the MASTER VOLUME control or connect components to the input jacks. • Muting of PRE OUT jack, HEADPHONE jack and SPEAKER terminals The PRE OUT jack, HEADPHONE jack and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power operation switch is turned on or input function, surround mode or any other set-up is changed. If the volume is turned up during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off before adjusting the volume. • Whenever the unit is in the STANDBY state, the apparatus is still connected on AC line voltage. Please be sure to turn the power off (£ off) when you leave home for, say, a vacation. 5
