to keep it intact for future, then use Backing up Settings procedure on page 4-38.
To use a factory-preset source file:
1. Highlight the channel with the desired source file and attach it to the
highlighted channel (see Section 3.8 on page 3-12).
2. Note that any adjustments to the “attached” source will also alter the data
from the original factory source file.
3.5.1. Internal Source
Every channel has a preset internal source shown as S OURCE 0 on the
S OURCES list. This is factory set “default timing” for the projector with
scanning rates of 33.3kHz (horizontal) and 59.3Hz (vertical) and is similar
to HDTV. This internal source is used to display menus when there is no
source input connected to the projector. To use this internal source,
select C
HANNEL 0, then press E NTER . This internal source can be copied
to any other channel but it cannot be cut, edited, or pasted to.
