Tone-Speaker
Clockwise rotation of this control increases the
treble response. Also, when turned cloekwise frorn
the SPEAKER position, the speakers are muted when
the recorder is in the RECORD mode. Complete coun-
terclockwiserotationof tNs control provides a means
to monitor recordings.
Speed Control
The speed control knob should point to 7.50 or
3.?5 according to the speed desired. This Recordio
has twotape speeds, ?.50-inches per second and 3,?5-
inches per second. Insofar as quality of recording-
reproductionis concerned, speed is an important fac-
tor. The higher the speed, generally, the greater will
be the fidelity.
Caution: Do not turn the speed control knob unless
the STOP button is depressed.

Preparing For Operation
1. Remove the AC power cord, reel of tape, empty
reel, and the microphone from the rear storage com-
partment.
2. Depress the STOP button.
3. Plug the AC cord into a convenient wall receptacle
of the proper rating.
4. Place the speed control knob in the 3.?5 or ?.50
position.
Caution: Donotturn speed control knob unless STOp
button is depressed.
When the forward (> ) or reverse (1) buttons
are depressed, the RECORD and PLAY buttons are
Iocked so they cannot be pressed down, with the pos-
sibilityof spilling tape. The buttons should always be
presseddownfirmlyuntilthey latch. The STOP button
mustbedepressedbefore changing functions or speeds
of the recorder.
Important: Always depress the STOP button when the
Recordio is not in use.
Threading The Tape
1. Placea reel of tape on the supply pan (Ieft) making
sure the reel slots catch the protrusions of the pan.
2. PIace an empty reel, the same si.ze or larger, on the
take-uppan (right). Again make certain the reel slots
catch the protrusions of the pan.
3. Releasethe STOP button by pressing lightly on any
one of the other buttons so that all buttons are in the
released position. This releases the tapebrakes, sim-
plifying tape threading.
4. Unwindaboutl4-inches oftape from the supply reel.
Hold a section straight with both hands and insert the
tape in the tape slot making sure the duII coated side
faces upward.
5. Insertthe free end of the tape into a slot in the hub
of the empty reel. While holdingthe tape in place, give
the reel tvo or three turns to secure the tape to the
reel.
To Record From Microphone
1. Insertthemicrophoneplug into the jack on the rear
panel labeled MIC.

2. With the STOP button depressed, turn the ON-OFF
VOLUME controltothe right (clockwise) until a "click"
is heard. Allow the recorder to warm up until the
REDI LITE is illuminated.
3. Place the speed control knob in the position de-
sired, As a general rule, 3.75-inches per second for
voice, and ?.50-inches per second for music.
4. Depress the PUSH TO RELEASE button with the
Iefthand and with the right hand depress the RECORD
button - then release the PUSH TO RELEASE button.
5. While holding the microphone about 3-4-inches away
from the mouth, speak in a normal tone of voice and
adjust the VOLUME control to the point where the
OVffi,LOAD indicator flashes at the louder or "peak"
passages.
Note: To monitor the sound being recorded, turn the
TONE-SPEAKER control to its extreme coun-
terclockrvise position. Care must be taken to
keep the microphone far enough from the re-
corder to prevent squeal due to acoustic feed-
back.
Rewind ( < ) 0r FastForward ( > )
When it is desirable to play a certain portion of
a tape over again, it is not necessary to rewind the
entire reel. By depressing the rewind ( < ) bution the
tape willreverse at a rapid speed. By depressing the
fast forward ( > ) button the tape will advance at a
rapid speed.
To Record From Radio 0r TV
Whileitis possible to record sound from an ex-
ternal source simplybyplacingthe microphone in front
of thespeaker, this is not recommended as background
noises willbe recorded alongwith the desired program
materials.
For noise free recordings, record directly from
the speaker voice coil terminals of the radio or TV re-
ceiver. For this purpose, a patch cord is available
from your Recordio dealer.
1. Inserttheplugof the patch cord into the jack on the
rear panel labeled iNPUT.
