Timer Controlled Record Operation
1. Connect your C-3 and stereo system to
the clock timer as shown in the diagram.
2. Make all the preparations as for normal
recording, but leave the deck in the stop
mode.
3. Set the clock timer for the desired start-
ing time.
4. Set the TIMER switch on the C-3 to
REC.
When the selected time arrives, power will
be applied to the C-3 and recording will
begin. When the tape reaches the end the
pinch roller will be released, the heads will
be lowered and the capstan motor will
stop. Power will still be connected to the
deck, however, and the control panel will
be inoperative. None of the buttons will
have any effect until the TIMER switch is
turned to OUT. Check that the cassette you
wish to récord on has its record protection
tabs in place otherwise the C-3 will go into
the play mode.
Timer Controlled Play Operation
1. Check that the C-3 is correctly con-
nected to the amplifier for normal
playback operation.
2. Connect the C-3 and amplifier to a clock
timer as for timer controlled recording
(above).
3. Make all preparations as for normal
playback, but do not set the tape in
motion.
4. Set the TIMER switch on the C-3 to
PLAY.
When the selected time arrives, power will
be applied and the C-3 will begin to play.
When the tape reaches the end the pinch
roller will be released, the heads lowered
and the capstan motor stopped. The control
panel will be inoperative and no button will
have any effect until the TIMER switch has
been set to OUT.
Over Dubbing (Punch in Recording)
During playback, you can go directly from
playback
mode
to
record
mode
by
holding
in the RECORD button and pressing the
play (> ) button at the same time. The
deck will begin recording from that location
while the tape continues to run. This opera-
tion is called “punch in” recording or
“running splice’. It allows you to record
over or correct a recorded section of the
tape without stopping the tape first and
then selecting record mode.
