The unit is switched on by pressing the POWER button (1);
the cassette holder illumination indicates that the unit is ready
for operation. Simultaneously, the protective cover for the
heads is retracted.
Tape Type Selection
Your HiFi cassette deck is equipped with a fourfold tape type
selector switch (13) which facilitates use of the tape types in
use today.
Consult the table (page 28) for the tape type to be used and
select the optimum operating position for this tape with switch
(13).
For tape types which you cannot find on the table the following
listing of tape data will help you to find the correct switch
position.

Musicassettes should be played in switch position Fe or Cr ac-
cording to the data on the cassette. If designation or other in-
formation on the tape type is missing, select switch position Fe.
DOLBY NR/MPX filter
The Dolby noise reduction system gives a lasting reduction of
the inherent tape noise and thereby increases the dynamic range
of the recording.
To play cassettes that have been recorded with the Dolby system
and which have the Dolby trademark DO, or Dolbyized recor-
dings you have made yourself as described in page 13, operate
the switch marked OO -MPX (15). The built-in Dolby system
then works automatically and needs no special adjustment
when used in conjunction with tapes listed on page 28 or their
equivalents.
The DOLBY NR switch is coupled with the MPX filter; this
means disturbing high frequencies during tape recording of VHF
programs are filtered out.
Select the correct switch position in accordance with the follow-
ing table.

Index Counter
The index counter (16) is a convenient means of noting and
quickly locating specific spots on a recorded tape. lt functions
during recording, playback and fast winding in any direction.
It is good practice to set the index counter reset knob (12) to
"000" at the beginning of each tape. If you note the number
on the index counter at the beginning of a particular selection
you can later quickly find all the selections on a particular cas-
sette.
Inserting and removing cassettes
Thanks to the unique cassette holder (DLL) the cassette can
be directly inserted. Hold the cassette in such a manner that
the tape faces downwards, insert the cassette top-edge first and
pivot it downwards to a vertical position until it clicks into
place (Fig. 2). The cassette removal is every bit as easy and can
be done at any stage of operation. The two STOP keys (2) cause
the tape movement to be stopped and the tone heads to be
retracted whenever the cassette is removed. In this way, no
separate stop key is necessary.
Fast forward and reverse
»» (9) fast wind from left to right
44 (5) fast wind from right to left
The functions "fast forward” pp and "fast reverse!’ 4 are used
to find particular points on the tape.
The device switches off automatically at tape end. Pressing the
keys "fast forward” (9) or "fast reverse” (5) cancels the functions
START » (7) and RECORD (4).
Start
Recording and replay are initiated by means of the » (7) button.
PAUSE
The PAUSE button (10) is used for preparing to record and
stop for brief interruptions in recording playback. The function
you have selected is maintained when the pause button is de-
pressed.
Pressing the pause button once more returns the equipment to
the preceding mode of operation.
Auto Stop
The equipment contains an electrical tape monitoring device
which initiates the auto stop. This unit functions independently
of tape foil and cassette. If operational defects such as jammed
cassettes occur, the unit automatically switches off the drive.
Monitoring with Headphones
The “PHONES” jack (22) may be used for stereo headphones
with an impedance of 4 — 2000 Ohms, for monitoring on both
record and playback.
Making your own cassette recordings
In addition to the notes previously given for playback, the fol-
lowing points should be observed for recording:
* Set the tape selection switch (13) according to the type of
tape used.
* Switch on DOLBY NR (15); if necessary switch on MPX
filter.
* Set the counter (16) to “000”.
Recording preparation and recording level setting
Press the PAUSE (10), RECORD (4) and » (7) keys in that
order. The RECORD key must be held depressed until the
> key has been pressed. The RECORD light (20) will show the
unit is ready for recording.
Using the input selection switch INPUT (17) select the desired
input source:
