WARNING
Make sure the lens cap is on
before removing or installing a lens assembly.
Grasp the lens assembly near the point where it enters the projector and slowly
unscrew (counter-clockwise) until the assembly is free from the projector. Use
both hands and take care not to touch the lens surface, which is easily damaged.
Set aside.
Make sure the new lens is protected by the lens cap. Install the new lens in the
projector by carefully screwing the assembly into the projector just until snug. If
the lens assembly seems difficult to turn, it may be cross-threaded. Carefully
remove and try again. Use both hands and do not force or over-tighten.
Remove lens cap and reposition the projector closer to or further from the screen
as necessary for the screen and new lens type. For example, if using a 1.2:1 lens,
throw distance should be roughly equal to 1.2
x
the screen width. Adjust vertical
offset as necessary so that display is rectangular.
If the projector is not operating properly, note the symptoms of the problem and
use the following guide to assist you. If you cannot resolve the problem yourself,
contact your dealer for assistance.
The power cord will not fit into the power socket...
1. A standard power cord is inadequate for the power requirements of the
VistaPro 2000 and will not fit into the projector's power socket. Use only the
notched power cord that came with the projector.
The projector will not turn on when
is pressed...
1. Make sure that
is held down for approximately one second and that
the projector has been off for at least 2 minutes.
2. Are both LEDs OFF on at the back of the projector? Check that the power
cord is properly connected at the both the wall outlet and the projector.
3. Does the green "Status" LED flash with each key press? If not, VistaPro
2000 is not receiving the keypad's IR signals. Ensure the keypad is directed
at either the front or rear of the projector, or at the screen. Also make sure
that the path between the IR keypad and the projector (or screen) is not
blocked.
4. The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing
Keypad Batteries for instructions.
5. The IR keypad may have been disabled by a change in protocol. See 2.10,
Keypad Protocols and 3.6, Controlling System Parameters.
6. Use
the
key on the built-in keypad to turn the projector on.
The projector is on but there is no display of source input...
1. Is an active source connected properly? Check the cable connections. Is that
source selected? Press
,
,
, or
to select a source. Or
use
to switch to other sources. See 2.4, Source Connections and 3.5,
Using Sources.
