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 light-
ing system).
• Before connecting this unit to other devices, turn off the power to all
units. This will help prevent malfunctions and/or damage to speak-
ers or other devices.
Placement
• Using the unit near power amplifiers (or other equipment contain-
ing 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.
• 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 (irregularites in color, or static). Should
this occur, reposition this unit so it is located at a greater distance
from such devices.

Owner's Manual

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, slid-
ers, 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 (includ-
ing padding) that it came in, if possible. Otherwise, you will need to
use equivalent packaging materials.
