The type plate is at the rear of the recorder.
Note: Do not expose the recorder for any great
length’ of time to excessive heat from heating
equipment or direct sunshine.
Connecting the recorder to the mains
Before connecting the recorder to the mains
ensure that voltage selector 6 is set to the local
mains supply. ff it is not, turn the voltage selector
with a suitable screwdriver until the correct voltage
value appears in the recess (fig. 5).
After this, insert the mains plug in the wall socket.
Warning: Always disconnect the mains lead before
opening the apparatus.
Note for users in Great Britain
When fitting a mains plug to the mains lead proceed as follows:
The wires in the mains lead are coloured in accordance with the
following code: Blue = Neutral; Brown = Live. As these colours
may not correspond with the colour markings identifying the
terminals in your plug proceed as follows: The Brown wire must
be connected to the terminal which is marked with the letter L or
coloured Red
The Blue wire must be connected to the terminal which is marked
with the letter N or coloured Black.
Note: This apparatus must be protected by a 3Amp Fuse if a
13 Amp plug is used or if any other type of plug is used by a5 Amp
Fuse either in the plug or adaptor or at the distribution board. If in
doubt consult 4 qualified electrician

Counter
Make a habit of setting counter @3 to ‘000’, by
pressing zero reset button @2, immediately after
inserting a cassette. By noting the counter reading
at which each recording commences, you will later
be able to locate any of your programmes rapidly
by fast winding or rewinding to the same reading.
Note: Tne counter does not directly indicate the
playing time of the cassette.
Automatic stop
The recorder incorporates a special mechanism so
that when the tape in the cassette has reached its
end, the motion of the cassette automatically stops
and any engaged tape transport keys are released.
The mechanism functions during recording, play-
back and fast winding.
Dynamic noise timiter - DNL
The dynamic noise limiter DNL - suppresses tape
noise, without affecting the natural timbre of
music.
It operates only during soft passages and in the
absence of signals on the tape. Noise need not be
suppressed during normal and loud passages, for
in these cases it is barely audible.
The DNL functions only during playback and
therefore has no effect on a recording operation.
The DNL is switched on and off with switch @).
Dolby system
In addition to the DNL this recorder is also
equipped with the Dolby system (Dolby NR - Noise
Reduction). In contrast to the DNL, the Dolby
system operates both during recording and play-
back. In the course of recording with the Dolby
system the high tones are recorded with additional
amplification during soft passages. If the Dolby
system is switched on during playback, the high
tones have their volume reduced again to their
normal level.
The advantage of this is that any tape noise is also
reduced to a lower level. Cassettes and musicas-
settes recorded with the Dolby system must
therefore be played back with the Dolby system
switched on, otherwise the high tones would be
accentuated. During playback of normally re-
corded cassettes the Dolby system must be
switched off. It is advisable therefore to mark the
cassettes which have been recorded using the
Dolby system.
The Dolby system is switched on and off with
switch 62).
Note: Both DNL and Dolby can be used together
during playback.
Connections
The recorder is fitted with DIN standard connec-
tion sockets. Equipment fitted with DIN connection
sockets can be connected to the recorder using
lead 4822 321 20207 (EL 3768/14). For the con-
nection of equipment and accessories fitted with
other than DIN plugs or sockets, adaptor leads and
plugs are available from your dealer. In the in-
terests of safety, consult your dealer if you wish to
connect equipment not having a recorder connec-
tion socket (e.g. a TV-set).
@ Socket @: output for stereo headphones
e@ Socket @): input for the right channel micro-
phone when making stereo recordings with two
