Numbers Select Main Image
Use Numbers Select Main Image to use the
numeric keys #1-8 as input keys. This remapping
of the keypad (see right) can be particularly useful
with PIP displays, providing a convenient shortcut
for changing the primary (background) image
without first having to return to the Main menu.
To use the keys in this manner all of the time,
even with single displays, select Always. For
normal keypad function, select Never (default).
Set to PIP Only to use activate number keys only
when PIP is in use.
NOTE: Numbers Select Main Image keypad
functionality works only when menus are closed.
The dual lamp illumination system used in this projector gives you the flexibility to
choose an operation mode (single lamp or dual lamp) to suit the specific needs of your
installation. The unique lamp auto-switching feature also provides the potential to
operate the projector for extended periods without interruptions related to lamps or
lamp replacement.
A complete understanding of how the projector works is critical in effectively
maintaining its continuous operation. The Lamp Menu and the options provided, such
as selecting a lamp operation or power mode and monitoring lamp status can help in
achieving bright, uninterrupted projection.

The projector by default is set to power on in Dual Lamp mode. No light appears on
the wall during the first 25 seconds of power up, as this is the time it takes to ignite
the lamps. As the lamps warm up to their full potential, you will notice brightness
gradually increasing. Before sending a keypad command, wait for the projector to
complete its initialization phase ("ON" will appear in the status LED display),
otherwise the request will be ignored. After this time, you can switch to one of the
Single Lamp modes or make any other software request.
On rare occasions, a lamp may not ignite on the first attempt. A brief description of
what you will notice in each of the lamp modes is described below.
•
In Dual Lamp mode, only the light from the lamp that successfully ignited
will be seen on the wall. In this case, the projector will wait 90 seconds and try
re-striking the lamp. The projector will attempt only 2 re-strikes of the lamp. If
it fails to turn the second lamp on it will automatically switch to the Single
lamp operation mode for the lamp that was successfully turned on. If during
one of its retries, the projector successfully turns the second lamp on, the lamp
operation mode remains in Dual Lamp.
If both lamps fail at the same time, an error is reported and the projector
automatically powers down.
