1 Powering ON
(a) Be patient when powering the projector ON or switching lamp operation
modes. As the lamps warm up, brightness will gradually increase. (No light
appears on the wall during the first 25 seconds.) On the rare occurrence a
lamp does not ignite, the projector will try again several times. (For more
information see 3.7 The Lamp Menu)
(b) Wait for the projector to complete initialization before sending keypad
commands ("On" will appear on the LED display), otherwise it will be
ignored.
(c) The projector enforces a 90 second wait from the time the projector is
powered down and powered back up again. This gives the lamps enough
time to cool down to a point where they can be turned on again.
(d) Use the windows located on the lamp doors as indicators when trying to
determine whether a lamp is on or off without accessing software menus.
2 Lamp Operation Modes – Auto Switching
(a) The projector is designed to run in Dual Lamp mode (default), unless
another mode is manually selected. If a lamp fails while in Dual Lamp
mode, the projector will try re-igniting the lamp — it will not switch to a
single lamp mode.
(b) The projector will automatically switch from one single lamp operation
mode to another to maintain light on the wall.
(c) Check the status of a lamp in the Status menu, Lamp menu or by looking at
the windows on the lamp doors.
(For more information see 3.7 The Lamp Menu)
3 Lamp Operation Modes – Manual Switching
(a) One lamp will turn off only after the other lamp has successfully been
turned on. This allows you to view content without interruption when
switching between lamp operation modes. It takes 25 seconds for a lamp
that was just turned on to warm up and reach full brightness. When the
original lamp turns off you will notice a slight dimming, which indicates the
lamp switching operation is complete. At this point, you can perform any
adjustment, such as Color Wheel Delay. (For more information see 3.7 The
Lamp Menu)
4 Flexible Light Output Control
(a) Switching from Dual to Single Lamp operation modes can reduce light
output by approximately 50%.
(b) Adjusting lamp power in the range of 300W to 250W can provide
approximately 17% dimming capability.
(c)
Adjusting the Optical Aperture can significantly drive brightness down
(approximately 78%) while increasing contrast from 1100-5000:1 increase
contrast.
(d) Always check the optical aperture and lamp power levels before
troubleshooting brightness related problems.
5 White Boost
(a) White Boost automatically turns off when Edge Blending, adjusting
Brightness Uniformity or making Color Adjustments. A noticeable dimming
of the display occurs. For best results, set White Boost to 10 for data content
and 2 for video.
