1-1 Adjustment Preparation
(1)
Keep DY stick to CPT funnel.
(2)
Turn ON the set and receive cross-hatch signal
(or circle pattern signal). Adjust the static conver-
gence coarsely according to item (VlII, 1-4).
(3)
Receive white pattern signal and adjust the white
balance according to item 4-6.
(4)
Set BRIGHTNESS control and CONTRAST con-
trol to maximum and apply heat-run to the set
with circle pattern signal received for 40 min. or
more.
1-2 Purity Adjustment
THIS ADJUSTMENT METHOD APPLIES TO
THE PURITY ADJUSTMENT BY USING
MICROSCOPE.
(1) Adjust coarsely White balance, Static conver-
gence (center) and Focus.
(2)
Receive circle pattern and heat-run more than T
minutes with CONTRAST and BRIGHTNESS to
maximum. Do not delete the raster nor vary the
current before fixing the position of DY. Heat-run
should be done with perfect raster. (DY and tilt
should have been coarsely adjusted.)

(4) Adjust the position of purity magnet and DY. Keep
the landing balance of
햴
and

, and adjust so that
the landing of
햴
and

is as follows while observ-
ing with a microscope.
