Auto Search & Temp Channel
Auto Search When a new source is introduced to the
projector, the projector will initially search
through the “user ” channel listing for a
match. If a match is found, this channel is
selected and the channel number is
displayed in the “Chan n, Select Channel”
command button located on the initial menu.
If no match is found in the “user” channel
listings, then auto-search will look through
the “factory ” read-only channel data for a
match. If a match is found, then thi s is
selected and the channel number displayed
in the “Chan n, Select Channel command
button is set to 0 (zero).
If no match is found in the factory channel
listing, then the projector will interpolate
between the next closest signal above and
below the current signal and establish a
temporary channel. Again, displaying 0
(zero) as the selected channel number.
User Channel List
The “user” channel list contains all user
established channels setups and some
common source setups from the factory.
Factory Channel List
The “factory ” channel list i s a read-only
listing that is originally created at the factory
and cannot be accessed directly by the
user. This list contains a variety (100+) of
common video and computer setups.
Temporary Channel
A temporary channel is denoted as a
channel that has either been copied from
the factory channel list or a new channel
created by syst em interpolat ion. A temp
channel is designated as Channel 0 (zero).

Channels
The temporary channel is never changed unless the user has changed at least one
parameter, i.e., Brightness, Contrast, H Pos etc.
Now assuming that at least one parameter has been changed, the temporary channel is
saved under either of the two following two circumstances;
At least 10 minutes ha s passed since the most rece nt change. This 10-minut e timer is reset
every time a parameter chan ge is made. If the tempor ary channel is saved under t his condition,
a new channel is created and t he projector is switch ed to this new channel. T he new channel is
set to the next open channel number and is tagged wit h the horizontal and v ertical frequencies.
A temporary channel is saved if any action is taken that causes a new or different channel to be
selected. This includes such actions as selecting a new channel manually, selecting a new source
manually, changing the input source so auto search forces a channel change, selecting this Help or
Edit Config, which both forces selection of the internal channel.
