Broadcast Key
Enter a checkmark if you want keypad commands sent to one projector to be relayed
to all projectors in a serial network. Note that the
Proj
key will temporarily “override”
the effect of a broadcast setting and allow you to control a specific projector when
necessary. Disable the setting for all but one (any) projector in a network.
Backlight
Toggle to turn the built-in keypad backlighting on and off.
Front IR / Back IR
As needed for your application, set to “on” so that the front and/or rear IR sensor
locations on the projector respond to the IR keypad. Set to “off” to disable.
To disable both IR sensors, you cannot use the IR remote keypad to select the second
OFF setting. This safeguard prevents accidentally disabling an IR keypad while you
are using it. Instead, use either the built-in keypad or a wired remote (optional) to set
the remaining active sensor to
OFF. The projector will no longer respond to an IR
remote keypad.
Wired Keypad
The wired keypad is ON by default to when connected to the rear of the projector. The
projector will then respond to incoming commands from this port. To disable the
wired keypad, you must use a different keypad—the built-in or an IR remote
keypad—to select “off”. This safeguard prevents you from accidentally disabling the
wired keypad during use.
In the Configuration menu, select
the Geometry and Color submenu
when you need to modify overall
color performance and/or image
geometry for all sources.
Test Pattern
Choose the desired internal test
pattern, or select OFF to turn off a
test pattern. Alternatively, use the
Test
key for cycling through test patterns.
Keystone
Use to correct a keystoned image shape in which both sides of your image are inclined
toward the top or bottom edge. Keystone is typically caused by tilting the projector in
relation to the screen, so that the lens surface and screen are no longer parallel to each
other.
