When HV Regulation, Item (0), is selected the cross
hatch is replaced with a black raster. A black raster
is required to perform this adjustment.
In the Coarse Adjustment Mode, the AUDIO but-
ton selects the following sub functions:
• CONV-GREEN --- Green Cross Hatch
• CONV-RED --- White Cross Hatch
• CONV-BLUE --- White Cross Hatch
• DF --- White Cross Hatch
In all the Coarse Adjustment Sub Functions, the
VIDEO button selects the Adjustment Item, and the
ADJUST, Up and Down buttons set the data.
CONV-GREEN is used to set Coarse Raster Ge-
ometry Correction. The Adjustment Items are listed
in Table 3-2. Before performing the adjustments in

justment Mode.
The adjustments under CONV-GREEN include
Width, Pincushion, X and Y axis Tilt, and Vertical
Keystone.
CONV-RED and CONV-BLUE are used to per-
form Red and Blue Coarse Dynamic Convergence
Adjustments. In both the Red and Blue modes, a
white Crosshatch is displayed. However, only Red
is adjustable in the Red Mode, and only Blue in the
Blue Mode.
The Adjustment Items under CONV-RED, and
CONV-BLUE, are shown in Tables 3-3 and 3-4,
respectively. These adjustments include:
