2) Werétommend regular cleaning of the heads and the pinch roller of the cassette deck and there are two ways of
cleaning these parts:
tl. using a cotton bud and methylated spirits.
To clean the relevant paris, you should press the ‘eject’ button so that the door is open. Ensure that the
power is switched off, then press the ‘play’ key, which will raise both heads and the pinch roller which can
then be cleaned with the cotten bud and methylated spirits.
ie using a commercial ‘head cleaning’ cassette as per the manufacturers instructions.
When carrying out this operation, please be careful not to exert tco much force on the cassette door as this may cause
damage.
Whilst it is appreciated that using a head cleaning cassette is a more convenient methad, this does tend to have a some-
what abrasive action and may increase the wear of the heads.
The cassette parts should be cleaned after approximately 25 hours use. However, it may be necessary to clean the
cassette mechanism at specific instances as some cassettes themselves have a deposit of oxide dust which may be
deposited on the relevant parts.
