67$786#/(6#0 Two LEDs (light emitting diodes) located to the right of the
Video Input Panel indicate Status (top) and Power (bottom). During normal
operation, the Power light is steady green and the Status light flashes green
each time a key is pressed or when the projector receives a serial command. Use
the following as a guide:
NOTE: A steady red power light accompanied by a coded pattern of red and
yellow flashes from the status light indicates an internal system error. Consult
the rear LCD display for an explanation. Should the problem persist, contact a
qualified service technician through your dealer or at Electrohome.
$&#/(#0 Indicates whether or not the projector is receiving proper AC current
(20 amps maximum). This LED should be 
2Q (green) whenever the projector is
plugged in. If it goes off during operation, this indicates that the projector
received more than 20 amps of current and that the projector’s circuit breaker
triggered an automatic shutdown of the projector.

restart by first moving the breaker back to the 
2Q position, then try powering up
as usual. If the breaker continues to “trip” (moving to 
2II), the projector will
remain inoperable until the AC problem is corrected. Never use the circuit
breaker as an

This keypad is located at the rear of the projector. An LCD window above this
keypad provides feedback regarding current status and activities of the projector.
The IR Remote Keypad controls the projector by way of wireless
communications from a battery-powered infrared (IR) transmitter. Use the IR
remote keypad the same way you would use a remote keypad supplied with a TV
or VCR. When making key presses, point the keypad either toward the screen or
toward the front or rear of the projector. One of two sensors on the projector will
detect the signals and relay the commands for internal processing.
The wired remote keypad connects to the front 3-pin XLR jack via a 50 ft.
extension cable. It is recommended when: %XLOW0LQö

Keep in mind the following guidelines:
4,
 Press keys one-at-a-time; there are no simultaneous key presses required.
5,
 For any key having an “*” (3RZH U-, for example), hold the key for a second or
two in order to toggle the function with a single key press. For other keys (or
to use a “*” key in conjunction with 
21 or 2))), a momentary press
similar to a mouse click is sufficient.

 Press the “lightbulb key” for approximately one second to temporarily
illuminate the backlight for the keys without sending any other command.

 , 21 , and 2)) repeat their “arrow” actions when held down. For
other keys, release and press again to repeat an action.
8,
 If you press a key while the projector is busy with another action, such as
during a power-up, the key press may not take effect.
When you turn on the projector it begins operating at presentation level, such as
an image from the most recently used source signal. The projector temporarily
leaves presentation level whenever you use the keypad to work with control
settings, display menus, or on-line help. For example, pressing 
0HQX after startup
displays the main menu — presentation level is no longer active, although the
image continues to be displayed in the background. Press 
0HQX again (or ([L W ) to
return to presentation level.
Specific keypad commands are explained below:

Press and hold for a second or two to turn the projector on or off with a single
key press. Or press 
3RZH U- followed immediately by 21 or 2)) if you want to
guarantee the correct toggle (useful if you are unsure of the present status).
NOTES: 
1) Whenever the projector is turned off, the lamp cooling fans remain
on for about five minutes to cool the lamp sufficiently
. Do not unplug the
projector unless the lamp cooling fans have shut off. 
2) It is a good idea to
avoid turning a projector back on until it has been off for at least five minutes.
Hot re-strikes of the lamp may reduce lamp life.

,QSXW
Press 
,QSXW   when you want to display from a specific source location, such
as a switcher connected serially to the projector’s switcher port. The first digit
represents the switcher number (usually 1-9, or “0” for one of the four inputs on
the projector), the second digit represents the slot number (1-9). For example:
,QSXW   = display data from switcher 1, slot 2.
NOTES: 1) Although you don’t need to use the input key unless a switcher is
connected to the projector, you can also use 
,QSXW to access the four input “slots”
on the projector itself: use
 
 as the first digit (representing the projector as the
switcher), then 
, ,  , or  as the second digit (the desired input slot
number).

Press 
&KDQ to select a channel representing a specific source setup defined and
stored in projector memory. Once you enter a channel number, the display will
automatically update according to the setup parameters defined for that channel.

whether it is really off or if the shutter is just closed. If you press 
3RZH U- and
simply hold it for a second or two in hopes of turning the projector on, the
projector will turn off if the projector is actually already on. Instead, to avoid the

Press 
&RORU to adjust the color saturation level, or the amount of color in a video

saturation level is displayed.

whenever you want to mute all display yet maintain access to all projector
functions. Open the shutter to regain the display.
NOTES: 1) Like standby, closing the shutter automatically reduces internal light

the projector’s resident test patterns. For example, 
)X QF will display a 128-
step grayscale pattern, or )X QF will display a scrollable list. A list of test
common pattern codes appears on the back of the IR remote keypad and in the
Service subsection later in this manual.
You can also use 
)X QF followed by a special 2-digit number to directly access
certain options in the Size / Position or Image Settings menus — this will enable
a second method for adjusting the option immediately, without going through the

To broadcast to all projectors in a network, press 
 )X QF.
NOTES: 1) Once 
)X QF is pressed in presentation level, the projector will not
respond to non-numeric entry until 2 digits have been entered or until 5 seconds
of inactivity have elapsed. 2) Certain engineering codes will freeze an image or
display an unfamiliar menu or image. Should you accidentally select one of
these special codes after pressing

The remote keypad and the optional wired keypad both store keypad operating
settings (called protocols) in memory. In some advanced applications, such as
when you want to use two separate keypads to control two projectors
independently, you may want to override the original protocol (called C) set at
manufacture for one of the keypads. See section 2.10, Keypad Protocols for
complete instructions on changing protocol.
