Supersonic SC-745, Instruction Manual

When the cassette is held with the recorded side upper-most and exposed tape facing the front, 

the protective tab will be found on the left rear of the cassette. 

All pre-recorded cassette are protected in this way to prevent accidental erasure of the 

commercial recording. “Protected” cassette will prevent the record button from being operated. 

If at any time you attempt to record and find that this button will not depress, never force the 

mechanism or it may be damaged. Check that a cassette has been loaded and that tab has not 

been removed. Recording on a cassette from which the tabs have been removed can be done 

by covering the tab openings with a piece of adhesive tape.

CARE OF CASSETTE MECHANISM 

Gently clean the tape head and pinch wheel/capstan assemblies after every 10 hours of using 

the unit. A range of cassette care products are available. 

The erase head and record/play head and the surface of the pinch roller are delicate and must 

not be touched with metal objects such as screwdrivers. You may find it easier to clean the 

assembly by pressing the PLAY button to bright head and pinch roller into view. Be sure to press 

the STOP button after cleaning the mechanism. 

Damage to the pinch wheel can occur if the unit is left in PLAY mode with the power switch off. 

Under no circumstances should you attempt to lubricate any part of the machine.
