Using the Lightbook Projector
2-9
After the projector returns to its normal operating temperature, turn the
main power switch off and back on to clear the over-temperature indicator.
NOTE: The remote control’s
/O
key will not function after an
over-temperature condition until the main power switch is turned off and on.
Projector Not Open
Both the
and
indicators will flash quickly if the projector is not
completely open. Make sure that the projector locks into the open position.
Replace Lamp
The indicator will glow red if the primary bulb burns out. The indicator will
flash if the spare projection lamp burns out. If both lamps have burned out,
you cannot continue your presentation until you replace the lamp. See page
4-2 to replace the lamp.
NOTE: When the lamp nears the end of its life, it may shut off without the
lamp staying on. If this happens, press the
button twice. If the lamp does
not stay on, switch to the spare bulb or replace it.
