Loosen the three captive screws on the lamp module.
WARNINGS: 
 To avoid burns, allow the projector to cool for at least 60 minutes before 
you replace the lamp.
 Do not drop the lamp module. The glass may shatter and cause injury.
 Do not touch the glass lamp screen. Fingerprints can obscure projection 
sharpness.
 Be extremely careful when removing the lamp housing. In the unlikely 
event that the lamp ruptures, small glass fragments may be generated. 
The lamp module is designed to contain most of these fragments, but 
use caution when removing it.
5
Carefully remove the lamp module by grasping and lifting the metal 
bail wire. Dispose of the lamp in an environmentally proper manner. 
6
Install the new lamp module, making sure that it is properly seated.
7
Tighten the three captive screws.
8
Replace the cover over the lamp module by inserting the tabs into the 
tab bays and pushing the rest of the cover down into place.
9
Plug in the power cable, press the power switch then press the Pow e r 
button to turn the projector back on.

Resetting the lamp timerIf the lamp timer has reached the maximum number of hours for the projec-
tor lamp, the LED on the projector ’s keypad will show a lamp error (see 
“LED Behavior” on page 46). To reset the lamp timer, simultaneously press 
the decrease volume button and increase volume button on the keypad for 
10 seconds. At that point the LED will turn green and you can power on the 
projector. You can also navigate to the Settings>Service menu and select

RS-232 commands Communication ConfigurationVisit our website for additional RS-232 settings and information.
To control this projector via RS-232, connect a null modem cable and set the 
control system serial port settings to match the following communication 
configuration: Command FormatAll commands consist of 3 alpha characters followed by a request, all 
enclosed in parentheses. The request can be a read request (indicated by a 
?) or a write request (indicated by 1 to 4 ASCII digits).
A read request example: 
(AAA?) where
( starts the command
AAA denotes the command
? denotes the read request
) ends the commandA read command returns the range and the current setting, for example:
A write request example: 
(AAA####) where
(starts the command
AAA denotes the command
#### denotes the value to be written 
(leading zeros not necessary)
) ends the command
Some commands have ranges, while others are absolute. If a number greater 
than the maximum range is received, it is automatically set to the maximum 
number for that function. If a command is received that is not understood, a 
? is returned. With absolute settings, 0 is off, 1-9999 is on. The one excep-
tion is the Power command, where 0 is off and 1 is on.
To assure the projector can process a command, wait 3 seconds before enter-
ing the next command.

							48 Error Conditions
Not all commands are supported for all projectors. If an unsupported com-
mand is issued, the command will be ignored. If a command is received that 
is not understood, a ‘?’ character will be returned indicating the command 
was not understood.LimitationsThe projector cannot respond to commands coming in at a high-rate. There-
fore, a delay must occur between commands to ensure that the command 
gets properly executed. To assure the projector can process a command, 
wait 3 seconds before entering the next command. 
The Step column refers to increasing or decreasing the menu bar position 
since the On-screen Display is not an exact match of values. For example, 
Step 2 changes the data by 2 through the CLI (Command Line Interface). 
The menu bar is up (or down) by 1.
