1. USER PRECAUTIONS

Avoid installing the unit near heaters, as well as locations exposed to direct sunlight as this may discolor or deform the unit's exterior.

Avoid using the unit in humid or dusty locations. Also, do not block air exhaust vents located on the top and side panels to prevent equipment failures. (BA-806/BA-823)

Keep beverages away from the unit as they may be spilt. Also, do not insert combustibles or metallic objects, such as hairpins and needles, into the unit to prevent fires, electrical shocks and equipment failures.

To avoid severe electrical shocks and possible catastrophic damage, never open the unit nor touch its internal components.

Always take hold of the plug to unplug it from the power outlet. Do not bend the power cord excessively nor place any heavy equipment on the cord as the cable may be damaged, resulting in fires or electrical shock.

Unplug the power cord from the wall outlet if the unit is to be stored for two weeks or more.

Avoid installing the unit on the unstable table or in vibratory locations as this may damage the unit or badly influence its operation.

Use a soft cloth to wipe off dust and grease from the front panel and case. When these parts are very dirty, dip the soft cloth in a small amount of neutral detergent, remove the dirt and wipe with a dry cloth. Never use thinner, benzine, alcohol, or other solvents, which may damage the unit's finish.
