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:

 

• 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.

 

• 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.

 

• 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.

 

• 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.
