VistaPro 2000 Users Manual3-2
INFRARED SENSORS  - The infrared (IR) sensors on the front and rear of VistaPro
2000 
receive infrared signals from the IR keypad for remote control of the
projector. For proper operation make sure that these sensors are not blocked.
ZOOM ADJUST  - The lens barrel of a zoom lens (optional) rotates to adjust the
size of the image at the current throw distance (projector-to-screen distance).
Note that minimum and maximum image sizes depend on the specific zoom lens
installed (see Section 5, Specifications).
FOCUS ADJUST - The focus knob adjusts the sharpness of the image at the current
throw distance.
VERTICAL OFFSET ADJUST - The vertical lens adjustment knob adjusts the vertical
position of the image in relation to the projector lens. See Section 2, Installation
and Setup for details.
COMPOSITE/S-VIDEO INPUT - Accepts a composite video and S-Video signal from
devices such as VCRs.
RGB INPUT - Accepts RGB and sync signals from devices such as computers.
RS-232 INTERFACE (WITH LOOP THROUGH) - Allows one or more projectors to be
remotely controlled by a computer or controller, and provides a communications
connection for Marquee
 and third-party (Extron) signal switchers.
AC LINE CORD INPUT -
 Accepts only
 the special VistaPro 2000
 notched AC line
cord supplied with projector. The projector requires AC power of 100 to 240
VAC, 50 to 60 Hz @ 11 amps.
WARNING:
 Use only the special VistaPro notched AC line cord.
Do not attempt operation if the AC supply is not
within the specified voltage and power range.
STATUS LEDS - 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 chart as a guide:

INFRARED REMOTE  KEYPAD - Keypad for controlling the projector from a
distance.
BUILT-IN KEYPAD - Alternative location for entering commands.
REMOTE JACK - Accepts a wired remote keypad for remote control of the
projector.
HARD RESET  - Emergency access for powering down the projector in the event
of a system failure. Insert pen point or small screwdriver.
You may use any of three different keypads to control VistaPro 2000:  The IR
Remote, the Built-in Keypad, or the Wired Remote Keypad (optional). Each
keypad provides complete control of the projector, however you may find one
keypad more appropriate than another, depending on your specific installation
and application.
On each keypad, some keys cause a direct action (such as 
 to turn the
projector on or off). Other keys provide access to actions via on-screen menus
and other windows. Keys labeled with both a direct function as well as a number
(such as 
 and  ) default to their direct function (in this case  ) unless
numeric entry is expected and required to complete a specific command — there
is no separate function key for enabling direct vs. numerical entry.
The built-in keypad is located on the back panel of the projector.

							OPERATION
VistaPro 2000 Users Manual3-4
The VistaPro 2000 IR Remote Keypad is the most commonly used keypad. It
controls the projector by way of  wireless communications from a battery-
powered infrared (IR) transmitter. Use the 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.
Figure 3-3. Infrared (IR) Remote or Wired Keypad
The wired remote keypad connects to the VistaPro 2000 remote jack via a 25 ft
extension cable. It is recommended when:
· the location of the keypad in relation to the projector or screen is inadequate
for IR Remote Keypad operation.
· the lighting conditions are unsuitable for proper IR transmission IR Remote Keypad

· you are controlling multiple projectors in the same room and need to control
each by its own remote keypad.
NOTE: This keypad is identical in appearance and key function to the IR remote
keypad that comes standard with the projector. See Figure 3.3
The following guidelines apply when using a keypad.
1) Press keys one at a time.
2) Hold down  for about a second in order to turn the projector on or off.
For other keys, a momentary press similar to a mouse click is sufficient.
3) Press  for approximately one second to temporarily illuminate the

keys, release and press again to repeat an action.
5) If you press a key while the projector is busy with another action, such as
during power-up, the key press may not take effect.
When you turn on the projector it begins operating at presentation level, which
displays either the Electrohome VistaPro logo or, if you have disabled the logo,
an image from an existing source signal. The projector temporarily leaves
presentation level when you use the keypad to change control settings, display
menus, or access on-line help. For example, pressing 
 after startup displays
the main menu of six triangular icons for access to specific functions —
presentation level is no longer active. Pressing 
 again (or  ) returns to
presentation level. Basic keypad commands are explained below.
Keypad operating settings (protocols)
The remote keypad and the optional wired keypad both can store keypad
operating settings (also 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
A) set during manufacture. See section 2.10, Keypad Protocols for complete
instructions on changing protocol.
Power ON/OFF
Press/hold for about a second to turn the projector on or off. The Electrohome
logo is displayed at startup until you select a source (see 3.5, Using Sources). If
desired, the logo can be eliminated from startup entirely (see Preferences menu).
NOTES: 1) Whenever the VistaPro 2000 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) The projector will not
turn on unless it has been off for about 2 minutes. Likewise, the projector must
be on for about 2 minutes before you can turn it off.
