1. You may have accidentally entered a special engineering code using the
key with certain numbers. Press to cancel the function and return to
presentation level.
2. If the screen blacks out, it is possible that excessive voltage noise on the AC
or ground input has interrupted the projector’s ability to lock on to a signal.
Turn the projector off, wait for the lamp fans to stop and unplug. Plug in
again and power up as usual.

1. Display adjustment may be required. Rotate the focus knob to adjust for best
focus, then adjust brightness, contrast and detail.
2. Is a BNC T-connector being used? Use a distribution amplifier to boost
signal levels.
3. Is the video input signal properly terminated? Set in Preferences menu.
4. The screen size may be too large. As screen size increases, magnification
increases, reducing brightness.

1. Display adjustment may be required. Adjust pixel tracking and phase.
2. The video input may not be terminated. Make sure the video input is
terminated (75
6
). If it is the last connection in a loop-through chain, the
video input should be terminated at the last projector only.
3. The signal cables carrying the input signal may be of poor quality. Use only
good quality signal cables. Electrohome cables are recommended.
4. The distance between the input source device and the projector may be too
great. If the distance between the input source device and the projector is
greater than 25 feet, signal amplification/conditioning may be required.
5. The input signal may be of poor quality.
6. If the source is a VCR or off-air broadcast, detail may be set too high.
