The
push-buttons
for
"fast-forward"
and
"fast-rew1nd"
(
Pos. I
&
2 lnflg,2
)
have two oper-
atlng
posltions
each. If
they
are
depressed only halfway, they do
not
lock and
the
correspondings
lights do not light up. Any deslred
point
on
the
tape can be located
easily
by
alternately depress-
ing these two buttons
halfway. The hand may be
rested
on the deck
for
this
purpose.
The requlred
polnt
may
be
located by means of the tlming lndicator. If a certain
place
has
to be found
by ear,
the tape must be brought into
contact with the replay head by means of the knuried wheel

,
If' one of the keys is
momentarily fully depressedthe
tape is
spooled
with full
speed and at
the
same
time, Ilfted off the
heads. It ls
posslble
to
go
from
"
fast- forward
"
directly into
"
fast-rewlnd
"
but the fast wind action can only be stopped by
pressing
the
"
stop
"
key. In case
of
tape breakage or at the end of tape, the machine is switched off automatlcally by
means of the
tape
tenslon balance,
The tape
may be monltored during
fast wind
by
operating the knurled wheel on the Ieft

Timlng Indlcator
A
new feature of this tlmlng lndlcator ls the
fact
that it is callibrated in
minutes
and seconds
instead of tape footage.
at
15 ips the time can be
read
directly
at 7
I/2
ips
the tlme read on the lndlcator should be multlplted by 2.
The
programme
duratlon is indlcated with the remarkable
accuracy
of better than
+
.3
%. This
includes
all
errors due to different
tapes,
sllppage,
etc. Thls
accuracy is
malntained
gven
during
fast
wlnd and makes the use of a stop-watch unnecessary in
most
cases.
The tlming lndlcator counts up to 99
mlnutes
59 seconds and is driven by
the large idler on the
right hand side.
The
tlmlng
indicator can be
re-set to zero by means of the re-set lever which is
accesslble
through
a slot
on the right hand slde of the machine. The counter may be re-set while the machine is
runnlng.
In order to start
tlmlng from the
beginning
of
a
recordlng, the re-set lever
can be kept
depressed on
the runnlng machine up to
a
given
cue.
For correct
zeroing of the counter, the re-set lever must be depressed fully up to the click. Where
several
recorders
are
lnstalled side by
side,
the re-set lever may be difficuit to reach. In this case,
an
extenslon lever may be obtained
as an additional
extra.
