A Note About Switching Lamp Operation Modes
The projector is designed with two lamps so that it can potentially maintain
constant light on the wall. It automatically detects a failed lamp and responds
by switching lamp operation modes and turns the other lamp on. You may
see a brief period of no light on the wall until the new lamp is ignited and a
gradual increase to full brightness.
When you manually select a new lamp operation, the lamp turns off only
after the new lamp has successfully been turned on. On rare occasions, a
lamp will not strike on the first attempt. The projector, in this instance, has
been designed to attempt a re-strike of the lamp. With the current lamp still
on, the projector waits 30 seconds before initiating another lamp strike.
During this time, on-screen messages will appear and an amber LED will
flash every second until the lamp is successfully turned on. The projector
attempts to re-strike a lamp up to 3 times after the initial change in lamp
operation modes. With the 30-second wait period in between each attempt,
the projector may seem like it is not responding for up to a total of two
minutes. You can press any key during this time to cancel and return to the
original lamp operation mode. If you cancel the operation or the attempts to
strike the lamp have failed, the lamp is declared, "failed to strike" and the
projector remains in the original mode.
The same occurs if you are attempting to switch from Single to Dual lamp
mode; the projector reverts to the single lamp mode for the lamp that is
working.
LAMP CONDITIONING
- Enable this option to reduce the noticeable flicker effects that
are sometimes generated by the lamp. Although this option is not typically required
during normal operation, enabling it will pulse-modulate the lamp, reducing the
flicker effects seen in the image. It may take minutes or hours for this option to reach
full effectiveness. By default, this option is OFF.
More, Lamp 1 or More, Lamp 2 –There are two separate lamp submenus that can
be accessed from the Lamp menu. Each submenu is dedicated to one lamp – you can
view specific lamp information, such as lamp hours, lamp history and the current
status of the lamp. You can also record a new serial number for a new lamp and
change lamp operation modes. (Figure 3.30.)
