Creating Your Own Startup Screen
You can transfer any image from your computer or video source to the 
projector, and then use it as your startup screen. You can also use it as 
the screen to be displayed when the projector is not receiving a signal 
or when you press the 
A/V Mute button. The image can be a 
company logo, slogan, photograph, or any other image you want to 
use. 
Capturing the Image
Start by displaying the image you want to use. It can be an image from 
either a computer or video source such as a DVD player or digital 
camera. Then follow these steps to capture the image and transfer it to 
the projector:
1. Press the 
Menu button on the remote control, highlight the 
User’s Logo menu, and press Enter.
2. When you see a message asking whether you accept the present 
image as the user’s logo, select 
Yes and press Enter.
3. A selection box displays over the image. Use the  pointer 
button to select the area of the image you want to use. Then press 
Enter.

■Highlight No-Signal Msg. if you want to display your image 
(instead of a blank screen) when there is no video signal 
incoming from the currently selected source. 
■Highlight A/V Mute if you want your image to appear when 
you press the 
A/V Mute button.
5. Select

Controlling Multiple Projectors
If you’re using more than one projector for your presentation, you can 
use the projector’s ID system to switch between them using a single 
remote control. To do this, you need to set a different ID for each 
projector. During the presentation, it’s easy to change the remote 
control’s ID to match that of the projector you want to use. When 
you want to switch, simply change the remote control’s ID to match 
that of your second projector.
Setting the Projector ID
The projector’s default ID is 1. Follow these steps to change it:
1. Press the 
Menu button on the remote control.
You see the projector’s menu screen. 
2. Select the 
Advanced2 menu and press Enter. Then highlight 
Projector ID and press Enter.
3. Press the right or left side of the  pointer button to increase or 
decrease the ID value. 
4. Press 
Enter to set the value.
5. When done, press 
ESC to exit the menu system.
note
By default, the remote 
control’s ID is set to zero, 
which allows it to control 
any projector. If you want to 
control multiple projectors 
simultaneously, and you 
don’t want to switch 
between them (each 
projector would need its own 
screen), you can leave the 
remote control’s ID set to 
zero. In this situation, you 
would not need to change 
the projector’s ID.

Changing the Remote Control ID
To change the remote control’s ID to match that of a projector, follow 
these steps:
1. Press the 
ID button on the remote control. You see it light. 
2. Press one of the numbered buttons on the remote control to select 
the ID of the projector you want to operate. 
The 
ID button’s light shuts off and the new ID is registered.
3. Repeat steps 1 and 2 each time you want to switch projectors.
To check the remote control’s current ID, do the following:
1. Press the 
ID button twice in succession. After a moment, the 
button flashes. 
2. Count the number of flashes; this number corresponds to the 
remote control’s ID. (If it doesn’t flash, the ID is set to zero.)

Customizing Projector Features
You can use the menu system to change the video signal input at 
certain ports, turn sleep mode on or off, adjust the network settings, 
change the language, and customize several other features.
Image Setup Options
Use these settings to change how the projector processes incoming 
video signals. Several of these settings should normally be left at the 
factory default setting (except for the 
Computer and BNC Input 
settings). 
■Computer Input (in the Setting menu)
Select the setting for the type of equipment you’ve connected to 
the 
Computer port:
Analog-RGB: For a computer connection
RGB-Video: For a video player that outputs an RGB video signal 
■BNC Input (in the Setting menu)
Select the setting for the type of equipment you’ve connected to 
the BNC ports: 
Analog-RGB: For a computer connection
RGB-Video: For a video player that outputs an RGB video signal
YCbCr: For a video player that outputs an NTSC component 
video signal
YPbPr: For a video player that outputs an HDTV component 
video signal
■Video Signal (in the Video menu)
Leave this setting at 
Auto unless you are using a 60-hertz PAL 
system (select 
PAL60). You can change this setting only if you’re 
displaying an image through the 
Video or S-Video port.  
						

							138Using the Projector’s Menus
■Progressive (in the Advanced 1 menu)
This setting should normally be left at its default setting (
Video 
or 
Film/Auto). Converts interlaced signals to progressive signals. 
When set to 
OFF, interlaced signals are processed without 
conversion (available for video signals only). 
■BNC Sync Termination (in the Advanced 2 menu)
This setting should normally be left 
Off (for TTL input). If an 
analog (75-ohm) terminator is required, as for a switcher, change 
the setting to 
ON. 
Remote Monitoring Setup Options
These options let you set up the projector so it can be monitored and 
controlled from a remote computer (see Chapter 7). 
■Standby Mode (in the Advanced 1 menu)
Select 
Network ON to enable the projector to be monitored over 
a network when it’s in standby mode. 
■Network (in the Advanced 2 menu)
Used for managing the projector over a wired network (see 
Chapter 7). If the network assigns addresses automatically, turn 
on 
DHCP. Otherwise, turn off DHCP and enter the projector’s IP 
Address
, Subnet Mask, and Gateway Address, if applicable. 
If you want to monitor the projector using a network 
management utility, select 
SNMP and enter at least one trap IP 
address. 
■COM Port (in the Advanced 2 menu)
Used for communicating with a computer running the EMP 
Link21L utility software. Select 
RS-232C or USB, depending on 
the port that’s being used for communication with the computer. 
Turn off the projector and then turn it back on for the new 
setting to take effect. 
note
When Standby Mode is set 
to 
Network ON, the 
exhaust fan continues to 
operate after the projector 
has cooled down. This is 
normal.
note
Press the Num button on 
the remote control to use the 
number keypad.

Miscellaneous Setup Options
■No-Signal Msg. (in the Setting menu) 
Selects a screen color or image to display when the projector is 
not receiving a signal. The logo setting displays an image that 
you previously transferred to the projector (see page 132).
■Sleep mode (in the Setting menu)
When sleep mode is on, the projector turns off the lamp if it 
has not received any input signals for 30 minutes. Turn sleep 
mode off if you want the lamp to remain on all the time (this 
is the default setting).
■Message (in the Setting menu)
Selects whether the image source or the color mode is 
displayed on the screen.
■Rear Proj. (in the Advanced 1 menu)
Turn on to project from behind onto a transparent screen.
■Ceiling (in the Advanced 1 menu)
Turn on when the projector is mounted upside-down from 
the ceiling.
■Language (in the Advanced 1 menu)
Select from nine languages to be used for the projector 
menus.
