(European model only) What is the Radio Data System?
Locating a station by program type (PTY)
You can locate a station you want by selecting a program type. The system tunes in the type of programs currently being broadcast from the RDS stations stored in the tuners preset memory. The types of programs include NEWS, AFFAIRS (current news), INFO, SPORT, EDUCATE (education programs), DRAMA, CULTURE, SCIENCE, VARIED (interviews, games and comedy), POP M, ROCK M, EASY M, LIGHT M, CLASSICS, OTHER M, WEATHER, FINANCE, CHILDREN, SOCIAL, RELIGION, PHONE IN, TRAVEL, LEISURE, JAZZ, COUNTRY (country music), NATION M (nations popular music), OLDIES, FOLK M, DOCUMENT (investigative features), TEST (test signal for emergency broadcast), ALARM (emergency broadcast) and NONE (any programs not defined above).
Radio Data System (RDS) is a broadcasting service that allows radio stations to send additional information along with the regular program signal. This tuner offers convenient RDS features like station name display and location of stations by program type. RDS is available only on FM stations.*
RDS may not work properly if the station you tuned in is not transmitting the RDS signal properly or if the signal is weak. * Not all FM stations provide RDS service, nor do they provide the same types of services. If you are not familiar with the RDS system, check with your local radio stations for details on RDS services in your area.

Other Features/Optional Components

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 system and have it checked by qualified personnel before operating it any further. The AC power cord must be changed only at a qualified service shop.
Tab of side B Break off the cassette tab of side A

Tab of side A

On placement
Place the system in a location with adequate ventilation to prevent heat build up. Do not place the system in an inclined position. Do not place the system in locations where it is: Extremely hot or cold Dusty or dirty Very humid Subject to vibrations Subject to direct sunlight.
Before placing a cassette in the tape deck
Take up any slack in the tape. Otherwise the tape may get entangled in the parts of the tape deck and become damaged.
When using a tape longer than 90 minutes
The tape is very elastic. Do not change the tape operations such as play, stop, and fast-winding frequently. The tape may get entangled in the tape deck.
