Figure 2.1.
Other display adjustments are available through keypad commands and on-screen
menus—refer to Section 3, Operation.
NOTE: Requires motorized lens, available as an upgrade.
Once you’ve defined lens settings for the current display, you can automatically
recall these positions whenever you use this channel. This Intelligent Lens System
TM
(ILS
TM
) function is particularly useful if you are working with a variety of source
types that may differ in size and/or aspect ratio, since the custom lens settings you’ve
chosen for any channel will be quickly and accurately applied whenever you use that
channel.
ENABLING ILS
TM
:
In the Lens Control menu, enable the “Intelligent Lens System”
option (highlight it and press
Enter
). This will add the 4 lens positions—focus, zoom,
horizontal and vertical offset—to the current channel settings recorded in projector
memory (see 3.5, Using Inputs and Channels if you are unfamiliar with channels).
The lens will then automatically reposition itself according to these lens settings each
time you use this channel. The ILS
TM
is a global function—any lens settings you
subsequently define for other channels will also be recalled whenever you use those
channels.
You can still change lens settings as usual when the ILS
TM
is enabled. Changes will be
recalled the next time you use the channel.
DISABLING ILS
TM
: To use consistent zoom, focus, and offset settings for all channels,
delete the “Intelligent Lens System” checkmark (highlight the option and press
Enter
).
The lens will not move until you adjust one of its settings.
Operating Tips for Lens Settings and ILS
TM
NOTES: 1) ILS
TM
requires motorized lens mount. 2) Accurate ILS
TM
performance
requires a calibrated lens mount. Calibrate after installation of a lens, and repeat if
the lens is moved or bumped. See Section 3.
When defining the focus, zoom, horizontal offset and vertical offset slidebar settings
for a given channel, keep in mind the following considerations for optimized ILS
TM
performance:
• The lens mount must be calibrated.
• When decreasing (
), values are always even (1004-1002-1000-etc.).
• When increasing (
), values are always odd (1001-1003-1005-etc.).
• Lens movements begin slowly and subtly before reaching full speed—changes
may not be evident on screen until after a second or two of
or .
• When holding
or , lens movement gradually accelerates.
• As with any setting, you can directly enter a value using the numbers on the
keypad, if desired. Press
Enter
before and after.
• Because of how gears function, movement to an even value is always
approached from a higher value, even if the direction of lens movement must
