1. Do not rub vertically or apply excess pressure to the Video Heads.

7.2.2. ADJUSTMENT PROCEDURES
7.2.2.1. BACK TENSION CONFIRMATION
Purpose:
To fine adjust the Back Tension so that the tape runs smoothly
with a constant tension.
Symptom of Misadjustment:
1) If the tape tension is less than the specified value, the tape
cannot come into proper contact with the Video Heads, resulting
in poor picture playback.
2) If the tape tension is too high, the tape will soon be damaged.
Equipment Required:
Back Tension Meter (Made in U.S.A., Purchase Locally)
VHS Cassette Tape (120-Minute Tape)
Specification:
22.4 gf±2.5 gf
(0.220 N±0.025 N)
1. Play back a T120 cassette tape from the beginning for approx. 10
to 20 seconds to stabilize tape movement.
2. Insert a Tension Meter into tape path and measure the back
tension.
