poor head-to-tape contact and deteriorates sound

the heads be kept clean at all times. With a stiff cotton

The capstan shaft, pinch wheel, tape lifter and other parts
over w h c h the tape travels should also be cleaned
TAPE LOADIEG
Place a full reel of tape o n the Supply Reel Table and an
empty reel on the Take-Up Reel Table. Thread the tape as
illustrated by the dotted lines in the figure on page 8.
If
automatic shut-off is desired, thread the tape through the
Automatic Shut-Off Lever and set Automatic Shut-Off

I-TRACK STEREO RECORDING PLAYBACK
SYSTEM
This model employs a 4-track stereo recording/playback
system which divides the magnetic tape into four tracks.
two of which are used simultaneously. The first stereo
recording/playback takes place on tracks 1 and 3, and the
second o n tracks 2 and 4 after the reels have been inverted.

Yormally, the steel pole pieces which form part of the
recording and playback head become slightly magnetized.
The effect of magnetization is that it will cause consider-
351s drop out or introduce noise into your recordings. I t is
recommended that head demagnetization be performed
2:riodically.
This can be accomplished with a bulk de-
3s-gnetizer by bringing it close t o the heads and making
lekeral small circ.ular motions over all head surface areas as
bell as the head housing.
Be sure to cut o f f the power o f the unit prior t o demagnetizing
the heads.
-
Both prongs o f the demagnetizer should be covered with masking
rape t o prevent the heads from being scratched.
*
Do not use magnetized tools in the vicinity o f the heads.
* Read the demagnetizer instructions carefully before operation.
