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.

2. CASSETTE TAPES  
Your tape player automatically detects the type of tape you are using,  
without having to switch a tape selector in accordance with the type of  
tape.  
The following three different cassette tapes are usable:  
Good!!  
(1) Normal tape  
(2)Chrometape  
(3)Metal tape  
Normal tape  
Chrome tape  
Metal tape  
The C-120 tapes (120 minutes' recording time for both sides) and  
endless tapes are not recommended because their tapes are extremely  
thin and can often be slack or twist, leading to unstable operation.  
No!!  
C-120  
Endless tape  
The C-90 (90 minutes) and C-60 (60 minutes) are most commonly  
used.  
Good!!  
C-90  
C-60  
To prevent damage of the tape and unstable operation, always store the  
cassette tapes in locations offering limited exposure to direct sunlight,  
high temperature, and magnetic effects (speakers and TV receivers).  
No!!  
If the slack or protruding tape is used, it may cause a tape twist around  
the pinch roller and capstan, or damage the tape. Before inserting the  
tape into the cassette player unit, take up the slack by inserting a  
pencil through the reel hub and turning it, as shown in the figure.
