Troubleshooting: Infrared
Is the room bright, or is direct sunlight present?
Is anything blocking the line of sight?
Are high intensity fluorescent lights present?
Notes:
The most common problems with infrared concern maintaining the line of sight between the transmitter and receiver, and interference from bright light. In some room setups, it may not be possible to maintain the line of sight with a personal infrared system (where both the transmitter and receiver are portable.) Make sure the speaker does not block the transmitter by walking in front of it, or moving papers in front of it. The same is true of the receiver. The student may inadvertently move objects in front of or accidentally cover the receiver. If this is not the problem, check to see if the lighting in the room is bright or from high intensity lights If these are in use, you may have to switch to a different transmitting method.
