Section 3: Operation

CHANNEL - A channel is a collection of measurements, locations and settings that tailor the display of a signal to your specific needs. Since source types and applications can vary greatly, you will likely want to adjust and define a wide variety of parameters, such as brightness, contrast, size, etc., in order to customize and optimize the display from or for a particular source. For example, the display settings you choose for a VCR source may be very different from those you choose for a high resolution computer source, or one signal may simply vary from another signal used previously through the same input location. Once you have adjusted a display parameter, such as pixel tracking or contrast, all current settings are collectively stored

in the projector’s memory as a unique 2-digit channel, such as . You can have

numerous distinct channels available for the same input, any of which can be selected by using the Channel key on the keypad followed by the 2-digit channel number.

Shown at right is a sample channel list as would be available from Channel . This is typically called the channel list.

	NOTE: The Channel key may display a channel list
	or not, depending on what you have defined for
	“Display Channel List” (see Menu Preferences
	later in this section).
	In order to access channels by using Channel on the
	keypad, you must first create the channels. See	Channel List
	below.
Creating a New	' To use a new source with the projector, a new channel must be added to projector
Channel	memory so that the projector will respond properly to an input signal from that source
– AUTOMATIC –	in the future. A new channel can be created automatically, as described here, or it can

be copied from an existing channel and then edited as necessary (see Copying or Deleting Channels later in this section).

When you select a direct input ( Input 1 , Input 2 , Input 3 , Input 4 , or Input 5 ), the projector’s existing channels are searched for matching input and signal parameters. If no match to the incoming input signal is found, a new channel is temporarily created based on factory-defined defaults for this type of signal. The channel number assigned is the lowest available number from 1-50.

NOTES: 1) An automatic channel will be discarded unless one or more of its parameters are changed, and will not appear in the channel list (see below). 2) If two channels have the same distinguishing source characteristics except for the reversal of sync connectors (i.e., H-sync and V-sync, are switched), they are still defined as distinct channels. 3) You cannot define a new channel without an incoming signal.

If the incoming signal does match an existing channel, the image will be set up and displayed as usual according to the parameters currently defined for that channel.
