necting cable; the Nakamichi 1000/700 Remote
Control may be connected to the remaining
socket to permit parallel control.
13 LINE FREQUENCY
Selects 50 or 60 Hz AC power
14 A.C. OUTLETS
Two outlets with a total power rating of 800W,
components to be controlled by the Program
Timer are to be plugged into these outlets.
Precautions
Make sure the total power consumption of
all components plugged into the Program
Timer is less than 800W.
. Make sure the proper frequency has been
selected with the rear panel switch.
. Avoid severe extremes in temperature and
excessive vibration as these will affect the
accuracy of the Program Timer.

Display
Functions
The timer may be set to show one
of four displays:
1. Time of Day — Under normal conditions
(when no other function buttons are de-
pressed) the display shows the time of day.
Time shown will be in hours and minutes
with an indication of AM or PM.
EXAMPLE: 12:28 A.M. (28 minutes
past 12 midnight)
2. Time of Day in Seconds — When the ‘‘Sec’”’
button is depressed, the display shows sec-
onds past the minute of the time of day. If
one were to press the ‘‘Sec”’ button in the
above example, a typical reading may be
8:12 , and this is read as 12:28 AM and
12 seconds.
(Depressing the ‘’Sec’’ button will always
give the seconds for the time of day regard-
less of whether the ‘’Timer’’ and/or the
“Sleep” button is “’on’’.)
é
Sleep Time Remaining — Depressing the
“Set” button while the “Sleep” switch is
on” will cause the display to show the
remaining sleep time in minutes.
a?
EXAMPLE: 758 (58 minutes
before shutdown)
. Start Time — Depressing the ‘’Set’’ button
while the ‘“Timer’’ switch is ‘‘on’’ will cause
the display to show the time for which the
system has been programmed to turn “on”
automatically.
Note:
(1)
(2)
The display features a power interruption
warning system. In the event a power fail-
ure or other accidental power shutoff
should occur, a portion of the display will
signal the failure upon restoration of the
AC power by alternately flashing on and
off. The flashing will stop once the time of
day has been reset.
When both the ‘‘Sleep’’ and the ““Timer”
switches are ‘“‘on’’, depressing the ‘Set’
button will cause the sleep time remaining
rather than the start time to be displayed.

c)
double-check to make sure the line freq-
uency is correctly set (see PRECAUTIONS);
make sure the “Sleep” and ‘‘Timer”’’ buttons
are in the “off” position (i.e., out);
plug the Program Timer’s AC cord into a
household outlet (do not be concerned
about the flashing segment of the display —
this is the power interruption warning
system — it will stop flashing once you
begin to set the time).
Begin by setting the seconds.
While holding the ‘’Sec’’ button down, de-
press the ‘’Fast’’ and “Slow” buttons simul-
taneously. This will reset the clock to
0:00
Keeping both the “Sec” and the “Slow”
buttons down, release the ‘‘Fast’’ button.
This will hold the count at zero.

per indication of AM or PM. The clock
segment of the DS-200 Program Timer its
now fully set.
To view the seconds at any given time,
depress the ‘’Sec”’ button.

Using the Automatic Timer
The automatic timer built into the DS-200 Pro-
gram Timer allows unattended radio broadcast
recording and various “‘wake-up” functions. In
the following discussion the term ‘“‘start-time’’
will refer to the specific time at which the
automatic timer will turn “‘on’’ the components
plugged into the Program Timer.
All audio connections among the various com-
ponents, i.e. the tuner, preamplifier, tape deck
and power amplifier, should be made as usual.
AC Power and remote control connections
should be made as shown in the diagrams at
right:

g) Since the power amplifier will not be re-
quired during the unattended recording, its
Power switch may be turned “off.’’
h)
Put
the
Timer
into
the
‘‘Record’’
mode
by
depressing
the
‘‘Record/Play’’
button.
The
Record
Indicator
will
light
to
show
that
the
system
is
in
Record
mode.
This
step
applies
to
recording
with
Nakamichi
models
1000
and
700
only.
The DS-200 will turn “on” the tuner, the tape
deck and the preamplifier at the desired start-
time. If recording with the 1000 or 700, and if
step (h) above has been properly executed, the
Timer will additionally put the 1000 or 700
into ‘‘Record”’ at the desired start-time. To take
the Program Timer out of the automatic timer
mode, simply depress the ‘“Timer’’ switch to
the ‘off’ position (i.e., out); the AC power to
the components will be immediately restored.
The next time the ‘‘Timer’’ switch is pushed
“on.” the same start-time will be in effect; but
take care to repeat step (h) when using the
Nakamichi 1000 or 700 because turning the
“Timer” off will return it to the “Play’’ mode.
Note:
(1) It is not necessary to set the seconds when
setting the desired start-time. The Timer
will turn ‘‘on”’ the system at the exact
minute. DEPRESSING THE “Sec,”
“Fast,” and “Slow’’ BUTTONS SIMUL-
TANEOUSLY AT ANY TIME, RE-
(2)
(3)
(4)
(5)
GARDLESS OF THE TIMER MODE,
WILL NECESSITATE RESETTING THE
TIME OF DAY.
The automatic timer will turn “off” all
components one hour after the preset
start-time. Maximum recording time with
the timer, therefore, is one hour (one side
-of a C-120 cassette).
As long as the start-time is not altered, the
automatic timer will turn “on” the com-
ponents once every 24 hours at the same
time if the ‘’Timer’’ switch is left ‘‘on.”
The ‘““Record/Play’’ button, however, must
be reset to the ‘‘Record’’ mode after each
cycle (applicable to models 1000 and 700
only).
The ‘‘Record/Play” button will not be
functional unless the “’Timer’’ button is
“on.” Always check the Record Indicator
lamp to make sure you have placed the
automatic timer into the ‘‘Record’’ mode
(applicable to models 1000 and 700 only).
Should a power interruption occur (as in-
dicated by a flashing segment), the start-
time will have to be reset in addition to
the time of day.

2) Using the DS-200 for Wake-up
a) All connections should be the same as for
unattended recording. |
b) Set the preamplifier for Tuner or Tape,
whichever is to be the source of wake-up
music.
c) Adjust the tuner for the desired station, or
load the cassette tape into the deck, and set
the desired listening level.
d) Set the automatic timer to the desired start-
time (wake-up time) in the exact manner as
for unattended recording (see step (e) of the
preceeding section).
e) If the tuner is to be the source, turn the
tape deck’s power switch “off.” If the tape
deck is to be the source, the tuner may be
turned “‘off."" If the Nakamichi 600 is to be
the source, make sure it is placed in the
Play/Pause mode.
f) Make sure the power switches for the pre-
amplifier and power amplifier are ‘‘on’’.
Note:
(1) If, when using the 1000 or 700 as the
playback source, you inadvertently put
the automatic timer into the ‘‘Record”’
mode (the Record Indicator lamp will be
lit), you can return it to the “Play’’ mode
simply by depressing the ‘’Record/Play”
button a second time.
(2) To double-check the automatic timer set-
baad
ting at any time, depress the “Set” button
while the ‘‘Timer’ switch is “‘on.’’ This
will cause the start-time to be displayed.
Using the Sleep Timer
With the DS-200 Program Timer it is possible to
listen to up to one hour of taped or broadcast
music while going to sleep without worry of
leaving any of the components “‘on”’ overnight.
In the following discussion ‘‘sleep time remain-
ing’ will refer to the amount of time left before
the system shuts down the power.
Make all AC connections as shown in the dia-
gram under ‘‘Using the Automatic Timer.”
Directions for setting the Sleep
Timer |
a) Set the Preamplifier as you would for nor-
mal! listening. The source may be the tuner,
the Nakamichi 1000, 700 or the 600 Cas-
sette Console (or any other tape deck with a
full shut-off feature that is plugged into the
Program Timer).
b) Turn the “Sleep” switch ‘’on” (i.e., push
in). This automatically sets the sleep time
remaining to 59 minutes. The system will
now shut down after 59 minutes of play.
c) It is possible to reduce the amount of sleep
time remaining as follows:
i)
While
the
‘‘Sleep’’
switch
is
still
‘‘on”,
depress
the
‘‘Set’’
button.
This
will
cause
the
sleep
time
remaining
to
be
displayed
in
minutes.
|
ii)
Keeping
the
“‘Set’’
button
down,
use
the
“Fast"’
and
“‘Slow’’
buttons
to
reduce
the
sleep
time
remaining
to
the
desired
amount.
Any
amount
of
time
from
59
rhinutes
to
1
minute
may
be
selected.
iii} When you have set the proper sleep time
remaining, release the ‘‘Fast’’ or ‘Slow’
button FIRST. Then release the ‘Set’
button.
Note:
(1)
Should
the
‘‘Sleep’’
switch
be
turned
‘’on”
when
the
‘“Timer’”’
switch
is
already
‘‘on,”
the
sleep
timer
will
not
automatically
reset
to
59
minutes.
Turn
the
“Timer”
switch
“off,”
and
then
depress
the
“Sleep”
3 switch.
(2)
If
the
“Sleep”
switch
is
turned
“off”
in
the
middle
of
a
sleep
cycle
and
then
sub-
sequently
restored,
the
sleep
time
remain-
ing
may
have
to
be
reset.
Check
the
sleep
time
remaining
with
the
‘Set’
button.
(3)
The
“Sleep”
switch
may
be
left
“on”
after
one
sleep
cycle.
It
will
not
repeat
every
24
hours
like
the
automatic
timer.
It
must
be
reset
before
every
use.

Using the Automatic Timer and
Sleep Timer Simultaneously
Since the automatic timer and sleep timer are
independent in their action, the two may be
used simultaneously. One may, for example,
fall asleep while listening to music and be a-
wakened by music from your stereo system.
Follow the directions for setting the automatic
timer and the sleep timer.
Special Uses of the DS-200
Program Timer
The accuracy and versatility of the Program
Timer allow its use for several special applica-
tions, such as elapsed time counting and inter-
val timing.
For these applications follow the directions be-
low:
a) Reset the clock to zero by depressing the
‘Fast’ and ‘‘Slow”’ buttons simultaneously
while holding the ‘‘Sec’’ button down.
b) Release only the ‘Fast’’ button to hold the
count.
c) Release the ‘‘Slow” button at the start of
the event. This will start the count.
d) For short duration events, hold the ‘‘Sec’’
button down. For longer duration events,
release the ‘’Sec’’ button; the count will
continue and the display will show hours
and minutes elapsed.
e) To momentarily hold the count, depress the
“Sec’’ and the ‘‘Slow” buttons simultane-
ously. To resume the count, release the
“Slow” button.
IMPORTANT:
The time of day must be reset after any such
special use of the Program Timer. The auto-
matic timer setting (start-time) is unaffected
and does not require resetting.
