PRECAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT
■ Although the cassette deck’s record/playback heads
used in this unit are high quality heads with
outstanding reproduction characteristics, they can
become dirty through the use of old tapes or from
dust accumulation over time. This can have a
serious effect on reproduction quality. Clean the
heads regularly with one of the commonly available
head cleaners or with cleaning solutions.
■ The voltage to be used must be the same as that
specified on this unit. Using this unit with a higher
voltage than that which is specified is dangerous and
may result in a fire or other type of accident causing
damage. YAMAHA will not be held responsible for
any damage resulting from use of this unit with a
voltage other than that which is specified.
■ The sound level at a given volume setting depends
on speaker location and other factors. Care should
be taken to avoid exposure to sudden high levels of
sound, which may occur when turning on the unit
with the volume control setting at high, and to
continuous high levels of sound.
■ Sudden temperature changes and storage or
operation in an extremely humid environment may
cause condensation inside the cabinet.
Condensation can cause the unit to malfunction.
To eliminate condensation:
• CD pickup
Leave the power on with no disc in the unit until
normal playback is possible (about 1 hour).
• Tape head
Leave the power on with no tape in the unit until
normal playback is possible (about 1 hour).
Note
If condensation forms on the tape head, foreign
matter may accumulate during use.
• Remote control
Wipe off condensation on the transmitter window
with a soft cloth before operating the unit.
■ This system is designed for using the provided
Active Servo Processing Speaker System for front
speakers. Therefore, do not attempt to connect
other conventional speakers to the FRONT
SPEAKERS terminals of this system.
■ Choose the installation location of this unit carefully.
Avoid placing it in direct sunlight or close to a source
of heat. Also avoid locations subject to vibration and
excessive dust, heat, cold or moisture. Keep it away
from sources of hum such as transformers and
electric motors.
■ Do not operate this unit upside-down. It may
overheat, possibly causing damage.
■ Never open the cabinet. If something drops into the
set, contact your dealer.
■ Always set the VOLUME control to minimum before
starting an audio source play: increase the volume
gradually to an appropriate level after play has
started.
■ Do not use force on switches, controls or connection
wires. When moving the unit, first disconnect the
power plug and the wires connected to other
equipment. Never pull the wire itself.
■ Do not attempt to clean the unit with chemical
solvents; this might damage the finish. Use a clean,
dry cloth.
■ Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before
concluding that the unit is faulty.
■ To prevent lightning damage, disconnect the AC
power plug and the antenna cable when there is an
electrical storm.
■ Do not plug the AC power plug to the wall socket
before you finish all connections.
■ Never allow metallic items (e.g. screwdrivers, tools,
etc.) to come near the cassette deck’s
record/playback head assembly in this unit. Doing so
may not only scratch or damage the head’s mirror-
smooth finish, it may change the magnetic
characteristics of the heads, causing a deterioration
in reproduction performance quality.
