IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages
2–4, please read and observe the following:
Power Supply
301
Do not connect this unit to same electrical outlet that is being
used by an electrical appliance that is controlled by an inverter
(such as a refrigerator, washing machine, microwave oven, or air
conditioner), or that contains a motor. Depending on the way in
which the electrical appliance is used, power supply noise may
cause this unit to malfunction or may produce audible noise. If it
is not practical to use a separate electrical outlet, connect a power
supply noise filter between this unit and the electrical outlet.
307
Before connecting this unit to other devices, turn off the power to
all units. This will help prevent malfunctions and/or damage to
speakers or other devices.
308
Although the LEDs are switched off when the POWER switch is
switched off, this does not mean that the unit has been
completely disconnected from the source of power. If you need to
turn off the power completely, first turn off the POWER switch,
then unplug the power cord from the power outlet. For this
reason, the outlet into which you choose to connect the power
cord’s plug should be one that is within easy reach and readily
accessible.
Placement
351
Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum. To
alleviate the problem, change the orientation of this unit; or move
it farther away from the source of interference.
352a
This device may interfere with radio and television reception. Do
not use this device in the vicinity of such receivers.
352b
Noise may be produced if wireless communications devices, such
as cell phones, are operated in the vicinity of this unit. Such noise
could occur when receiving or initiating a call, or while
conversing. Should you experience such problems, you should
relocate such wireless devices so they are at a greater distance
from this unit, or switch them off.
354b
Do not expose the unit to direct sunlight, place it near devices
that radiate heat, leave it inside an enclosed vehicle, or otherwise
subject it to temperature extremes. Also, do not allow lighting
devices that normally are used while their light source is very
close to the unit (such as a piano light), or powerful spotlights to
shine upon the same area of the unit for extended periods of time.
Excessive heat can deform or discolor the unit.
355b
When moved from one location to another where the temper-
ature and/or humidity is very different, water droplets (conden-
sation) may form inside the unit. Damage or malfunction may
result if you attempt to use the unit in this condition. Therefore,
before using the unit, you must allow it to stand for several
hours, until the condensation has completely evaporated.
356b
Do not allow rubber, vinyl, or similar materials to remain on the
unit for long periods of time. Such objects can discolor or
otherwise harmfully affect the finish.
359
Do not paste stickers, decals, or the like to this instrument.
Peeling such matter off the instrument may damage the exterior
finish.
Add
Do not allow objects to remain on top of the unit while it is in
operation.
Maintenance
401a
For everyday cleaning wipe the unit with a soft, dry cloth or one
that has been slightly dampened with water. To remove stubborn
dirt, use a cloth impregnated with a mild, non-abrasive detergent.
Afterwards, be sure to wipe the unit thoroughly with a soft, dry
cloth.
402
Never use benzine, thinners, alcohol or solvents of any kind, to
avoid the possibility of discoloration and/or deformation.
Additional Precautions
553
Use a reasonable amount of care when using the unit’s buttons,
sliders, or other controls; and when using its jacks and
connectors. Rough handling can lead to malfunctions.
556
When connecting / disconnecting all cables, grasp the connector
itself—never pull on the cable. This way you will avoid causing
shorts, or damage to the cable’s internal elements.
557
A small amount of heat will radiate from the unit during normal
operation.
558a
To avoid disturbing your neighbors, try to keep the unit’s volume
at reasonable levels. You may prefer to use headphones, so you
do not need to be concerned about those around you (especially
when it is late at night).
559a
When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise, you
will need to use equivalent packaging materials.
562
Some connection cables contain resistors. Do not use cables that
incorporate resistors for connecting to this unit. The use of such
cables can cause the sound level to be extremely low, or impos-
sible to hear. For information on cable specifications, contact the
manufacturer of the cable.
921
To prevent malfunction and/or damage to speakers or other
devices, always turn down the volume, and turn off the power on
all devices before making any connections.
941
Once the connections have been completed (p. 11), turn on power
to your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction and/or
damage to speakers and other devices.
When powering up:
Turn on the power to the AC-60
last
.
When powering down:
Turn off the power to the AC-60
first
.
942
This unit is equipped with a protection circuit. A brief interval (a
few seconds) after power up is required before the unit will
operate normally.
Add
Wrap the AC cord around the cord hook when trans-porting or
storing the unit.
945
If you need to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from the power
outlet. Refer to
Power Supply
