Lamp information
Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is 
automatically calculated by the built-in timer. The method of calculating the 
equivalent lamp hour is as follows:
Total (equivalent) lamp hour
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
See Setting Lamp Mode as Economic below for more information on Economic mode.
The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That 
is, using the projector in Economic mode helps to extend the lamp hour by 1/3.
To obtain the lamp hour information:
1. Press Menu/Exit and then press  /  until the SYSTEM SETUP: Advanced 
menu is highlighted.
2. Press   to highlight Lamp Settings and press Mode/Enter. The Lamp 
Settings page displays.
4. You will see the Equivalent Lamp Hour information displaying on the menu.
5. To leave the menu, press Menu/Exit.
You can also get the lamp hour information on the INFORMATION menu.
Extending lamp life
The projection lamp is a consumable item that normally can last up to 3000-4000 
hours with proper usage. To keep the lamp life as long as possible, you can do the 
following settings via the OSD menu.
• Setting Lamp Mode as Economic
Using Economic mode reduces system noise and power consumption by 20%. If 
the Economic mode is selected, the light output will be reduced and result in 
darker projected pictures.
Setting the projector in Economic mode also extends the lamp operation life. To 
set Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > 
Lamp Mode menu and press  / .
• Setting Auto Power Off
This function allows the projector to turn off automatically if no input source is 
detected after a set period of time to prevent unnecessary waste of lamp life.
To set Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off 
menu and press  / . The time period can be set from 5 to 30 minutes in 5-minute 
increments. If the preset time lengths are not suitable for your presentation, select 
Disable. The projector will not automatically shut down in a certain time period. 
						

							Maintenance 52
Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears suggesting it is time 
to replace the lamp, please install a new lamp or consult your dealer. An old lamp 
may cause a malfunction in the projector and in some instances the lamp may 
explode.
CAUTION
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too 
hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator 
still lights up after turning the power back on, please contact your dealer. See Indicators on 
page 56 for details.
The following Lamp warning displays will remind you to change the lamp.
StatusMessage
The lamp has been in operation for 3000 
hours. Install a new lamp for optimal 
performance. If the projector is normally run 
with Economic Mode selected (See Lamp 
Mode (Normal) on page 48), you may 
continue to operate the projector until the 
3950 hour lamp warning appears.
The lamp has been in operation for 3950 
hours. A new lamp should be fitted to avoid 
the inconvenience when the projector runs 
out of lamp time.
The lamp has been in operation for 4000 
hours. 
It is strongly recommended that you replace 
the lamp at this age. The lamp is a 
consumable item. The lamp brightness 
diminishes with use. This is normal lamp 
behavior. You can replace the lamp whenever 
you notice that the brightness level has 
significantly diminished. If the lamp is not 
replaced beforehand, it must be replaced 
after 3000 hours usage.
The lamp MUST be replaced before the 
projector will operate normally.

disposal laws. See www.lamprecycle.org 
• To reduce the risk of electrical shock, always turn the projector off and disconnect the 
power cord before changing the lamp.   
• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes 
before replacing the lamp.
• To reduce the risk of injuries to fingers and damage to internal components, use caution 
when removing lamp glass that has shattered into sharp pieces.
• To reduce the risk of injuries to fingers and/or compromising image quality by touching 
the lens, do not touch the empty lamp compartment when the lamp is removed.
• To assure optimal performance from the projector, it is recommended that you purchase 
the InFocus projector lamp for lamp replacement.
• If lamp replacement is performed while the projector is suspended upside-down from the 
ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury 
or damage to the human eyes caused by fractured lamp.
1. Turn the power off and disconnect the projector from the wall socket. If the 
lamp is hot, avoid burns by waiting for approximately 45 minutes until the lamp 
has cooled.

and scatter broken glass in the projector.
• Do not place the lamp in locations where water 
might splash on it, children can reach it, or near 
flammable materials.
• Do not insert your hands into the projector after 
the lamp is removed. If you touch the optical 
components inside, it could cause color 
unevenness and distortion of the projected 
images.
6. As shown in the figure, lower the new 
lamp first into the connector on the 
projector and align the two holes on the 
projector.
