MAINTENANCE
MAINTENANCE
Lamp
HIGH VOLTAGE
HIGH TEMPERATURE HIGH PRESSURE
Contact BOXLIGHT before replacing the lamp.
For the optional lamp, see the item “Optional Parts” of the Table \
12.
Before replacing the lamp, switch power OFF, remove the power cord from \
the power outlet, and
wait approximately 45 minutes until the lamp has cooled. The lamp may ex\
plode if handled at high
temperatures.
Lamp Life
Projector lamps have a finite life. The image will become darker, and hu\
es will become weaker,
after a lamp has been used for a long period of time. 
Replace the lamp if the LAMP indicator is red, or the CHANGE THE LAMP me\
ssage appears
when the projector is switched ON. See Table 9 of P.20 and Table 10 of P\
.21.
•The LAMP indicator is also red when the lamp unit reaches high temperatu\
re. Before
replacing the lamp, switch power OFF, wait approximately 20 minutes, and\
 switch power ON again.
If the LAMP indicator is still red, replace the lamp.NOTE
WARNINGAmercury lamp used in this LCD projector is made of glass and has high
internal pressure.  The mercury lamp can burst with a big noise due to d\
eterioration
resulting from a shock, crack and passage of time, and can end its servi\
ce life in unlit
condition.  Lamps also have a considerably different service life and ca\
n sometimes end up
in burst or turn to unlit condition soon after use.  Furthermore, when t\
he lamp is blown up,
glass fragments can get scattered around the lamp house and some gas con\
taining mercury
inside the lamp can leak out of the projector’s air vent.
• Handle the lamp with utmost care as it can burst during use if subj\
ected to a shock or
impact or if scratched or cracked.
• Probability for the burst will increase if the lamp is used for ext\
ended period of time or
used exceeding the period of replacement.  You are advised to follow ins\
tructions for lamp
replacement as soon as they are given (Refer to Table 9 of Page 20, Tab\
le 10 of Page 21).
Avoid any reuse of an old lamp (used lamp) since such reuse can result\
 in burst.
• In case the lamp gets blown up in a short period of time after use,\
 some electrical failures
or troubles other than the lamp itself may be suspected as causes.  Unde\
r such
circumstances, consult BOXLIGHT.
• Should the lamp burst (accompanied by a big bursting noise), perf\
orm ventilation
sufficiently, and exercise maximum caution not to inhale any gas out of \
the projector’s air
vent or not to let it enter your eyes or mouth.
• Should the lamp burst (accompanied by a big bursting noise), make\
 absolutely sure to
unplug the power cord from the outlet. 
You should not engage in cleanup or replacement of the lamp by yourself since scattered 
glass fragments can damage the inside of projector or can result in personal injury when 
you handle it. 
• When you dispose of any used lamps, be sure to observe and follow l\
ocal ordinances and
regulations of the area or district where they are subjected to disposal\
.  Generally speaking,
the lamps are treated similarly as glasses and bottles in most cases, bu\
t there are areas or
districts where lamps are classified as a separate collection, and so be\
 sure to use caution. 
• Never use the lamp in a state where the lamp cover is removed.

operation within ten minutes of switching power ON. The power will be turned off automatically in
over 10 minutes.
1. Switch power ON, and press the RESET button, for approximately three seconds. The ‘LAMP
xxxx hr’ message will appear on the lamp timer on the bottom of the screen.
