VOLTAGE & CYCLE CONVERSION
Voltage
This model is equipped with a built-in step-down trans-
former offering six stages of power voltage from 100 V to
240 V AC for world-wide operability. The voltage is preset
at the factory according to destination. However, the
operator is requested to check the setting prior to operation
and if necessary, adjust as follows: (A) Remove Fuse Post
by turning in direction of arrow. (B) Reset Voltage Selector
Plug so that proper area voltage shows through the Plug
cut-out. (C) Change fuse according to voltage: 100 V to
120 V: 1.5 A, 125 V fuse; 200 V to 240 V: 1 A, 250 V
fuse. (D) Tighten Fuse Post.
.Be sure to disconnect power cord before attempting to readjust
voltage.
.The line voltage should be held within a 10% deviation of
standard area voltage.
Cycles
Correct tape speed cannot be obtained if the Cycle
Conversion Switch on rear panel is not properly positioned.
Set to 50 Hz or 60 Hz according to area power source.
TAPE SPEED SELECTION
This model can be operated at either 7-1/2 or 3-3/4 ips tape
speed. Simply depress Tape Speed Selector Switch according to desired speed. The recording time with an 1800 ft.
tape is as follows: (stereo) 3 hrs at 3-3/4 ips; 1.5 hrs. at
7-1/2 ips; (monaural) 6 hrs. at 3-3/4 ips; 3 hrs. at 7-
i/2 ips.
DIRECT FUNCTION CHANGE SYSTEM
This model employs a direct function change control
system for speedy mode selection. The necessity of
depressing the Stop Key before changing modes is eliminated. Further, the controls are equipped with individual
colored lights which indicate each operating mode.
.When extremely thin tape of over 2,400 ft. in length is used, to
avoid tape damage, it is imperative that the Stop Button be
depressed before changing modes.
FAST FORWARD & REWINU
For rapid forwarding of the tape, depress Fast Forward
Key, and for rapid rewinding of the tape, depress Rewind
Key. This feature enables fast selection of your favorite
programs.
AUTOMATIC STOP & SHUT-OFF
One of the exclusive features of this model is the automatic
stop and shut-off functions of the unit. For automatic stop
(to stop reel movement at the end of the tape), leave the
Automatic Stop/Shut-off Switch at OUT position. For
automatic shut-off (to cut off the power of the entire unit
at the end of the tape), depress the Automatic Stop/
Shut-Gff Switch to IN position.
.If automatic shut-off is desired after one complete reverse cycle,
affix sensing foil to outside of tape at desired reversing point and
depress the Automatic Stop/Shut-Off Switch.
.If automatic continuous reverse is desired, apply sensing foil to
the outside of the tape for normal to reverse operation, and to
the inside of the tape for reverse to normal operation, at desired
reversing points and leave the Automatic Stop/Shut-Off Switch at
OUT position. Note that in this case, if the Automatic Stop/
Shut-Off Switch is depressed, automatic shut-off will be effected
at the end of one complete reverse cycle and the power of the
entire unit will be cut off.
.The AC Outlet at the rear of the recorder is inter-locked with the
Automatic Stop/Shut-off Switch so that if another machine is
connected to this outlet and the Automatic Stop/Shut-Off Switch
is depressed, the power of both units will be cut off when
automatic shut-off is effected.
PAUSE CONTROL
This model is equipped with a Pause Button for moment-
arily stopping recording or playback function. Pause
control is especially convenient for editing tapes; i.e., when
a certain portion of the program is not desired, depress the
Pause Button. Note that the Pause Indicator La~p will light.
Simply depress again to release.
REMOTE CONTROL
