Settings Displayed in Customer Menus: When adjusting a
bar graph setting in the Video and Audio Menus, a number
is displayed showing the actual numeric value stored in
EEPROM for that setting. On menu items without a bar
graph setting, two dashes indicate that the Factory Mode
is on.
•
Video Preference Settings Inhibited: In the Video Menu,
the Custom Video Preference settings are inhibited while
the Factory Mode is on and will NOT be stored in EEPROM.
(This allows the factory to temporarily change the settings
and not store them permanently.)
01 Preset Px: Used to store the customer menu adjust-
ments in the nonvolatile memory of the EAROM. Set-
tings for Contrast, Brightness, Color and Tint are stored
in this manner. 0 is Custom and 1 is Preset.
02 Preset Ax: Saves your custom audio settings (Bass,
table, balance, audio mode, Soundrite, front surround,
speaker) in nonvolatile memory (not affected by power
loss). Memory status is indicated by a 1 for "custom
settings already stored", or 0 for "custom settings have
not been stored."
03 Power Manage: Used for saving energy. When set to
0, Power Manage is off. The number represents the
hours that the TV will remain on, unless there has been
activity from either the control panel or remote.
04 Vert Pos: Moves Captions and displays vertically on
the screen. Use the ADJUST keys.
05 Horz Pos: Moves Captions and displays horizontally
on the screen. Use the ADJUST keys.
06 Band/Afc: There are 8 possible settings for this op-
tion.
0 = Broadcast Fixed
5 = CATV Fixed
6 = HRC Fixed
7 = ICC Fixed
07 Min Volume: Determines the minimum volume level
allowable with the VOLUME (VOL) Up/Down Control.
In this way, for example, someone cannot set the vol-
ume too low to hear. The factory default is 0, which
provides full range of volume control. It may be best
to set the same value on every TV.
