IMPORTANT NOTES
In addition to the items listed under “IMPORTANT SAFETY
INSTRUCTIONS” and “USING THE UNIT SAFELY” on
pages 2 and 3, please read and observe the following:
Power Supply
Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
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.
Placement
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 inter-
ference.
This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
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.
Excessive heat can deform or discolor the unit.
This unit contains powerful magnets. If placed in the
vicinity of TVs, it may cause interference (irregularities in
color). Should this occur, reposition this unit so it is
located at a greater distance from such devices.
Maintenance
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.
Never use benzene, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or
deformation.
Additional Precautions
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.
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.
•A small amount of heat will radiate from the unit during
normal operation.
To avoid disturbing your neighbors, try to keep the unit's
volume at reasonable levels (especially when it is late at
night).
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.
