If you wish to record on а tape protected in this way, it is only
nnecessary to close the slots temporarily by means of a small
piece of adhesive tape.
Please note that the additional slots present in Cr02 tapes must
not be closed by adhesive tape.
Head
The built-in 2/4-track M + X-sound head has excellent magnetic
characteristics for recording and playback in conjunction with
high resistance to wear.
The dual-gap erasing head guarantees complete erasure of recor-
ded program material, even with the new metal type, which is
somewhat critical in this respect.
Compact cassette system
Your
HiFi stereo cassette deck is of the 2/4-track type. This
means that the total width of the tape is subdivided into four
tracks with one pair of stereo tracks in each running direction,
thus providing. double recording and playback time in compari-
son with conventional 2/4-track decks in stereo mode.
Stereo recordings made with your cassette deck may be repro-
duced on any monaural cassette deck which means that stereo
and mono cassettes are fully compatible. Your cassette deck
also permits reproduction of recordings made with other cas-
sette recorders.
Maintenance
It is recommended
that you clean tape heads, capstan, pinch
roller and tape guides at regular intervals.
Use a piece of clean linen cloth or a cotton swab
(such as
Q-Tips), soaked
in alcohol
for cleaning.
Do not use metal
tools, such
as tweezers for cleaning and avoid touching the
tape head surfaces with your fingers. Clean the pinch roller
with a dry, lint-free cloth.
Long-time lubrication of all bearings, joints and other friction
points assures trouble-free operation of your cassette deck for
years. Do not attempt to lubricate the unit yourself, since only
special lubricants can be used. Other repair and maintenance
work must only be carried out by qualified service technicians
or your nearest authorized Dual service center.
