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. Select “Always” to use the keys in this manner all of the time, even with single displays. For normal keypad function, select “Never” (default). Set to When PIP Active to 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
	Menu		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.
About lamp operation,		f The projector by default is set to power on in Dual Lamp mode. No light appears on
modes and auto-switching			the wall during the first 25 seconds of power up; 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.
