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 lter
between this unit and the electrical outlet.
The AC adaptor will begin to generate heat after long hours of con-
•
secutive use. This is normal, and is not a cause for concern.
Should you prefer to use batteries, please use the alkaline batteries
•
or nickel-metal hydride batteries.
When installing or replacing batteries, always turn o the power on
•
this unit and disconnect any other devices you may have connected.
This way, you can prevent malfunction and/or damage to speakers or
other devices.
Before connecting this unit to other devices, turn o the power to all
•

•
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.
This device may interfere with radio and television reception. Do not
•
use this device in the vicinity of such receivers.
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 o.
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.
When moved from one location to another where the temperature
•
and/or humidity is very dierent, water droplets (condensation)
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.

•
reasonable levels (especially when it is late at night).
When you need to transport the unit, package it in the box (includ-
•
ing padding) that it came in, if possible. Otherwise, you will need to
use equivalent packaging materials.
Some connection cables contain resistors. Do not use cables that in-
•
corporate resistors for connecting to this unit. The use of such cables
can cause the sound level to be extremely low, or impossible to hear.
