HEAD DEMAGNETIZING
The steel pole pieces which form part of the recording
and playback heads become slightly magnetized after
several recording and playback hours and as a result,
the tape is partially erased at high frequencies. There ­
fore, head demagnetizing is recommended periodically.
1. Turn off Power Switch.
2. Remove cassette tape from receptacle.
3. With cassette receptacle at ejected position, remove
receptacle lid as in HEAD CLEANING procedure.
4. Demagnetize heads and other parts which contact
the tape with a Head Demagnetizer by bringing the
prongs of the demagnetizcr close to the heads and
withdraw by making small circular motions over the
entire hcad block area. Please read the instructions
accompanying the demagnetizer carefully.
TAPE ERASING
Any signals previously recorded on the tape will be
automatically erased as a new recording takes place.
For erasing only, no plugs should be connected to the
input jacks and Recording Level Controls should be
kept at minimum. For quick and complete erasure,
a bulk tape eraser is recommended.
LUBRICATION
Although thiS machine has been sufficiently oiled for
prolonged use, for maximum service and optimum
performance, please take your machine to your local
authorized AKA! agent for occasional motor lubrica­
tion.
