4-I. STRT CHANNEL (Start Channel)
When active, this function allows you to
determine the initial channel number when the
TV is turned ON. This feature is useful for an in-
house information channel, since the TV would
always select that channel when it is turned on.
Setting this to 255 causes the last channel
viewed when TV was turned off to be the tuned to
channel when the TV is turned on again.
The range of values is 0 - 255. Use (adjust) keys
to choose numbers that determine the start
channel.

5-I. CHAN LOCK (Channel Lock)
CHAN LOCK is ideal if a cable box (or similar) is
the sole source for programming—and the TV
must always be on the same channel. Changing
channels with Channel Up/Down or keypad
numbers is impossible. Channel Lock is inactive
when set to 0 (default).

7-I. START VOLUME
This function allows the Installer to determine the
initial volume level setting when the TV is turned
ON. This feature is useful for an in-house
information channel, since the TV would always
select that volume level when it is turned on. The
range of values are 0- 63, 255. If 255 is selected,
the current volume level will be retained in
memory when the TV is turned off; at TV turn on,
volume level is automatically set to the previous
or last level.

ADJUST. The factory default is 0, which provides
full range of volume control. It may be best to set
the same value on every TV.

value setting higher than in the MAX VOLUME
level (described below).
