- KEEP THE RECORDING HEADS CLEAN
Tape heads an periodi ally build up a oating of oxide residue from the passage of the tape over them. We
re ommend you lean the heads periodi ally using 99% Isopropyl Al ohol or a spe ially manufa tured tape
head leaner. Use foam appli ators or surgi al otton appli ators and lean in the dire tion of the tape
movement.
Tape head leaner and appli ators may be pur hased from any ele troni s dealer.
Do not use denatured al ohol, as it ontains ex ess impurities whi h an damage the tape heads.
Do not use ommer ial otton swabs, as they an leave fibers whi h an damage the tape heads.
- CARE OF CASSETTE TAPES
Store tapes in their ases to prevent dust and dirt from oming in onta t with the tape surfa e.
Do not tou h the tape surfa e with your fingers.
If the tape has unraveled, insert a pen il or similar obje t into the spro ket and tighten to remove sla k. (See Pi ture 1.)
Wind the tape until it is even and tight with a
pen il.
Tou hing the surfa e of the tape with
your finger will damage sound quality
by transferring skin oils and dirt.

Application of The Antenna
Application of The Antenna
- FM RECEIVING ANTENNA
The ele tri wave of FM broad asting is weakening in hills and valleys, around buildings and in iron-
reinfor ed buildings.
- INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM
Listening to the broad asting, fix the antenna after de iding the lo ation and the dire tion so that the re eption
may be optimized.
- INSTALLATION OF ANTENNA USING THE COAXIAL CABLE
Noisy re eption may o ur in built-up areas and fa tory sites as well as around power ables. This may be the ase
even when an antenna is used ex lusively for FM. In these regions, install the antenna using 75Ω oaxial able.
- INDOOR ANTENNA
In the regions where FM broad asting is heard omparatively well due to the near distan e to the station or
wooden stru ture, you an re eive broad asting of good quality by using T-type antenna.
- AM LEAD ANTENNA
Fix one end of a six to eight metre length of vinyl- oated single able to the AM terminal and the other end to
a high pla e like a wall.
- AM OUTDOOR ANTENNA
Install the vinyl- oated able to an outdoor pla e if the AM re eption is not good enough.
- AM LOOP ANTENNA
Conne ting the feeder of the loop antenna of the terminal of 300Ω.
Listening to the broad asting, fix it after de iding the lo ation and the dire tion so that the re eipt ondition
may be optimum.
