NOTE: Turn down the amplifier or receiver when
dubbing in Hi-Speed mode; as the tape speed is
twice as fast there is much more high frequency
energy than with normal speed and can potentially
harm loudspeakers and headphones.
ACCIDENTAL ERASURE PREVENTION.
Whilst making a new recording any previous
recordings already on the tape will automatically be
erased. If you wish to protect a tape from being
erased or re-recorded accidentally, you can remove
the tape's protection tabs. This way the record func-
tion will not engage. Please note that most pre-
recorded tapes commercially available already have
the tabs removed. Using adhesive tape over the
holes will enable the circuits to record again.
CrO2 (type II) and Metal (type IV) tapes have addi-
tional holes in the cassette housing, enabling the
deck to "recognize" the various tape types. Make
sure you do not cover these holes as well! Refer to
figure 3.
MAINTENANCE
The bearings and other moving parts have been
factory treated with special lubricants and do not
need any special attention.
Dirt, dust and tape oxide can potentially damage
the heads and tape guidance, besides degrading the
sound quality both on play-back and recording. Parts
in direct contact with the tape therefore need to be
cleaned regularly.
NOTE: Make sure the receiver or amplifier is
switched off before cleaning or demagnetising the
heads.
CLEANING
Open the cassette compartment door. At the bot-
tom of the compartment you can see the heads and
tape guidance (capstan and pinch-roller). Refer to
figure 4.
Clean the heads (A & B) and the capstan (C) using
cotton wool buds with pure alcohol or with a dedicat-
ed Tape Recorder Cleaner.
Clean the pinch-roller (D) using only distilled
water. Never use alcohol on the roller, as the rubber
will dry out. Alternatively, you can use a special
cleaning cassette. Be sure to use a cassette that
cleans all parts illustrated in figure 4.
DEMAGNETIZING
Parts in direct contact with the tape will become
slightly magnetic over time. This magnetism will
increase hiss, both during play-back and recording.
It is therefore advisable to demagnetise the heads,
pinch roller and other metal tape guidance parts from
time to time, using a demagnetiser or a demagnetis-
ing cassette. Follow the instructions of the demagne-
tiser or demagnetising cassette.
WARNING
Keep demagnetisers away from your tapes, they
can accidentally erase the recordings.
