The Polycom  Administrator’s Guide for the VSX 

Series contains troubleshooting information that 

can help you identify and correct issues 

associated with the VSX 8000 and the accessories 

connected to it.
The Rear Projection SMART Board 3000i 

Installation Guide contains troubleshooting 

information that can help you identify and 

correct issues associated with the display and its 

annotation capabilities.
The table below lists other issues that can occur 

with the Polycom Instructor RP system.

SMART

Does not respond to touch 
control.

The touch screen is not calibrated 
for the camera or video source in 
use.

Calibrate the touch screen.

Screen is blank.

The system is in standby.

Touch the screen. If that does not 
activate the system, press the green 
projector lamp power button on the 
pen tray.

Annotation color is different 
from the color of the pen.

The pens were not placed in the 
tray that matches their color (the 
color of the annotation is the color of 
the tray, not the color of the pen).

Place the pen in the tray that 
matches its color.

Annotations appear bigger 
than what you draw or write 
on the screen, they appear in 
the wrong place, they do not 
appear at all, or they appear 
erratically.

The camera or video source is not 
calibrated correctly. If the touch 
screen is out of calibration for the 
camera or video source in use, 
annotations may appear several 
times bigger than what you draw or 
write on the screen or they may 
appear in the wrong place, and 
touch control may be disabled or 
erratic. If this occurs, you must 
recalibrate the touch screen.

Calibrate the cameras and video 
sources again according to the 
steps in the Calibrate the Annotation 
Box section on page 12.
