3 CAUTIONS ON HANDLING
l 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.
l Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER
terminals
The PRE OUT jack, HEADPHONE jack and SPEAKER terminals
include a muting crrcuit. Because of this, the output signals are
greatly reduced for several seconds after the power 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 functionrng. Always wait
until the muting circuit turns off before adjusting the volume.
