Safety and Precautions
• Do not install the thin client in areas where it can become wet or 
be exposed to water.
• Only use the power cord shipped with the thin client.
• Ensure there is four inches of space surrounding the thin client. 
Inadequate ventilation can damage the device.
If your TC8900 Thin Client contains a smart card reader:
Prevent ESD (electrostatic discharge) damage to smart 
card readers by always discharging your body and smart 
card before using a reader (for example, by touching a 
grounded, unpainted, metal object). ESD can vary depending on 
many environmental conditions, including clothing that users wear 
and how they handle smart cards. ESD damage can potentially 
cause unsupported card reader behavior including failure. Always 
perform ESD prevention steps before using the card reader.
