Connecting the recorder to the mains - fig. 2
Before connecting the recorder to the mains, check if the mains
voltage as shown on type plate @§ corresponds to your local mains
supply. If it does not, get your dealer or service organisation to
adjust the voltage setting. The mains lead @4 may then be unwound
and the mains plug inserted into the wall socket.
Important note for users in U.K.:
The version /15 (see type plate 9 is not fitted with a mains plug.
When fitting a mains plug to the mains leads, 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 fllows:
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 3 Amp fuse if a
13 Amp plug is used. If any other type of plug is used, by a 5 Amp
fuse either in the plug or adaptor or at the distribution board. If in
doubt, consult a qualified electrician.
Switching on and off
The recorder is switched on by pressing mains switch@). Depend-
ing on the position of track selector (, the recording level meters
© or @ or both will then light.
The recorder is switched off by pressing the mains switch) again.
Ensure that the tape is brought to a standstill by pressing the stop
button @ before switching off the apparatus.
Inserting the tape - figs. 1 and 3
The recorder will accept either plastic or metal reels with a
diameter up to 18 cm andis suited for use with tapes of thickness
from 25 to 55 micron (1 micron ‘um’ = 0.001 mm). Thus, in
addition to ordinary Long-Play (LP) tape, Double-Play (DP) tape
may also be employed. Triple-Play (TP) or Super-Long-Play tape of
a thickness less than 25 micron is not recommended.
Threading the tape is very simple because in the stop position the
pressure roller (4) (fig. 9) retracts into the apparatus.
@ The reels should be attached to the reel discs by placing them
over the spindles @) and turning the top of the spindles 60 degrees
(fig. 3). The reels are then firmly clamped to the discs.
@ Attach a full reel of tape to the left-hand reel disc. This reel must
turn anti-clockwise as the tape unwinds.
e@ Attach an empty reel to the right-hand reel disc. The diameter of
the empty ree! must be large enough to accomodate the entire
tape from the full reel.
@ Unwind about 30 cm of tape and lead it around the tape tension
stabilisers @) and under the head cover (fig. 1).
@ Lead the end of the tape between the flanges of the empty reel,
draw a short piece through the threading slot in the flange, press
the start of the tape against the reel and turn the reel anti-
clockwise until it begins to take up the tape.
If the empty reel has no threading slot, insert the end of the tape
between the flanges of the reel, press it against the inner side of
the core and turn the reel anti-clockwise until it begins to take up
the tape.
@ Switch on the apparatus by pressing mains switch (6). Then
press start button @% and keep it depressed until the coloured
leader tape and the metal switching foil have passed the switching
contact © (fig. 9), then press stop button @.
Automatic stop
When the metal switching foil at the start and the end of the tape
passes the switching contact © (fig. 9), the motion of the tape is
stopped and the depressed buttons are disengaged.
lf tapes without metal switching foil are used, the depressed
buttons will be disengaged after a few seconds by the integral
tape-breakage protection mechanism.
Tape counter
Make a habit of setting the tape counter @ to zero by pressing the
zero reset button immediately after threading a tape. The counter
reading at which each recording on the tape commences, maybe
noted on the index card of the tape storage box. Later, a recording
can be swiftly located by fast forward winding or rewinding to the
counter reading concerned.
Tape travel buttons
The tape travel buttons are of the ‘tip touch’ type and they control
the mechanism via a servo motor, the so-called ’servo-control’.
The incorporation of logic circuitry precludes wrongful operation
and
makes
it
possible
to
switch
