IMPORTANT NOTES

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.

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.
