Precautions

On operating voltage
Before operating the system, check that the operating voltage of your system is identical with the voltage of your local power supply.

Cleaning the cabinet

Use a soft cloth slightly moistened with mild detergent solution.
To save a tape permanently
To prevent a tape from being accidentally recorded over, break off the cassette tab from side A or B as illustrated. If you later want to reuse the tape for recording, cover the broken tab with adhesive tape.

On safety

The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off. Unplug the system from the wall outlet (mains) if it is not to be used for an extended period of time. To disconnect the cord (mains lead), pull it out by the plug. Never pull the cord itself. Should any solid object or liquid fall into the component, unplug the stereo system and have the component checked by qualified personnel before operating it any further. The mains lead must be changed only at the qualified service shop.
When you are using a TYPE II (CrO 2) or TYPE IV (metal) cassette, be careful not to cover the detector slots which allow the tape player to automatically detect the type of tape.

Detector slots

On placement
