Safety
Radio interference
Electrostatic discharge (ESD) precaution
WARNING: This is an FCC Class A product. In a domestic
environment, this product may cause radio
interference, in which case, the user may be
required to take adequate measures.
WARNING: Circuit board components are vulnerable to damage
by electrostatic discharge (ESD). ESD can cause
immediate or subtle damage to sensitive electronic
parts. An electrostatic charge can build up on the
human body and then discharge when you touch a
board. A discharge can be produced when walking
across a carpet and touching a board, for example.
Before handling any board, make sure you dissipate
your body’s charge by touching ground. This
discharges any static electricity build-up.
