NOTES: 1. Since these settings are precisely factory adjusted, in
general, they should not be re-adjusted. If it is specifi-
cally required, a special meter is needed.
2. To facilitate adjustment, the deck should be placed in
a vertical position.
3. For the reels mounted on both left and right reel!
tables, use the same size ones.
4, Before all the following adjustments (2-8-1 ~ 2-8-3),
perform next instructions in order to activate the rele-
vant circuit.
a. Thread the tape to lift up both tension/shut-off
arms,
b. Set the POWER switch to ON.
c. Leave the deck as it is for 5 to 10 minutes.
5. There should be almost equa! values between tape
tension at point A during fast forward mode and at _
point B. during rewind mode.
