Cassette Maintenance
Cassette Maintenance
- KEEP THE RECORDING HEADS CLEAN
Tape heads can periodically build up a coating of oxide residue from the passage of the tape over them. We recommend you clean the heads periodically using 99% Isopropyl Alcohol or a specially manufactured tape head cleaner. Use foam applicators or surgical cotton applicators and clean in the direction of the tape movement.
Tape head cleaner and applicators may be purchased from any electronics dealer.
Do not use denatured alcohol, as it contains excess impurities which can damage the tape heads.
Do not use commercial cotton swabs, as they can leave fibers which can damage the tape heads.
- CARE OF CASSETTE TAPES
Store tapes in their cases to prevent dust and dirt from coming in contact with the tape surface.
Do not touch the tape surface with your fingers.
If the tape has unraveled, insert a pencil or similar object into the sprocket and tighten to remove slack. (See Picture 1.)
Wind the tape until it is even and tight with a pencil.
Touching the surface of the tape with your finger will damage sound quality by transferring skin oils and dirt.

To disable a tape so it cannot be recorded over, locate and remove the safety tab opposite the tape opening.
Holding the tape with the opening facing down, the tab to the upper left corresponds to the side facing you. (See Picture 2.)
*To remove the tap, push it down gently with
a screwdriver.
* To record again, cover the window with

Application of The Antenna
Application of The Antenna
- FM RECEIVING ANTENNA
The electric wave of FM broadcasting is weakening in hills and valleys, around buildings and in iron­reinforced buildings.
- INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM
Listening to the broadcasting, fix the antenna after deciding the location and the direction so that the reception may be optimized.
- INSTALLATION OF ANTENNA USING THE COAXIAL CABLE
Noisy reception may occur in built-up areas and factory sites as well as around power cables. This may be the case even when an antenna is used exclusively for FM. In these regions, install the antenna using 75Ω coaxial cable.
- INDOOR ANTENNA
In the regions where FM broadcasting is heard comparatively well due to the near distance to the station or wooden structure, you can receive broadcasting of good quality by using T-type antenna.
- AM LEAD ANTENNA
Fix one end of a six to eight metre length of vinyl-coated single cable to the AM terminal and the other end to a high place like a wall.
- AM OUTDOOR ANTENNA
Install the vinyl-coated cable to an outdoor place if the AM reception is not good enough.
- AM LOOP ANTENNA
Connecting the feeder of the loop antenna of the terminal of 300Ω. Listening to the broadcasting, fix it after deciding the location and the direction so that the receipt condition may be optimum.
