Automatic repeat
The recorder enables you to repeat the programme on a cassette
automatically by pressing automatic repeat button®. . As soon as
the tape reaches its end during recording or playback, the
recorder switches automatically to the rewind position ('rew') and
the cassette will rewind until the beginning of the tape. The
recording just made will then be played back or, if the apparatus
was already in the playback position, the tape will be played back
again.
The cassette will then be repeated again and again, until action is
taken by pressing stop button n or eject key ,s.
When the automatic repeat facility is switched off by pressing
button ®again, the cassette will be recorded or played back in the
normal way until the end of the tape, afterwhich the automatic stop
comes into action. If in addition to the automatic repeat button®
also the 'memory stop' button® is switched on, the cassette will
stop as soon as counter 3o reads '000' during playback, fast
winding or rewinding.
Maintenance
It is advisable to remove at regular intervals the dust and dirt which
has collected on the heads. This should be done after say, every
50 hours of operation or, on average, once a month. For this
purpose we recommend our special cleaning cassette, type
811/CCT, which is played through once as an ordinary cassette
with the recorder set for playback.
The heads may also be cleaned however using a soft cloth or a
cotton bud. To clean in this way proceed as follows:
• Ensure that the recorder is disconnected from the mains.
• Press eject key®. .
• Moisten the cloth or cotton bud with a little alcohol or pro-
prietary cleaning spirit.
• Nowclean the fronts of the heads®,©and©(Fig. 7).Allowthe
heads to dry.
• Then take a second cotton bud or cloth and moisten it with
water.
• Wipe off the heads®, © and®, and then dry them.
Note: The capstan is covered with a special protective coating.
Because of this, the capstan and the pressure roller must not be
cleaned with alcohol or cleaning spirit, see mark X in Fig. 7. You
may if necessary, clean the capstan® with dryfilter paper as it is
used for coffee filters (Fig. 8).
• Never use any other cleaning agents and do not touch the heads
or the capstan with sharp or metal objects.
Allow all parts to dry before reconnecting the recorder to the
mains.
• The transparent cover of the cassette holder® may be cleaned
using a soft cloth as shown in Fig. 9 and 10.
• Do not lubricate the apparatus!
It is recommended to have the recorder checked by a qualified
service engineer about once a year.
