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.
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.
