• Communication devices such as: personal computers, computer routers,
television sets, VCRs, wireless routers (wireless broadband, wi-fi, or 802.11)
or other cordless telephones.
• Excessive heat sources.
• Noise sources such as a window with traffic outside, motors, microwave
ovens, refrigerators, or fluorescent lighting.
• Excessive dust sources such as a workshop or garage.
• Excessive moisture.
• Extremely low temperatures.
• Mechanical vibration or shock such as on top of the washing machine or
