WARNING
The HID system incorporates components that might be affected by electrostatic discharge currents flowing
through certain component terminals. The main source of electrostatic discharges is human body, especially
under low humidity conditions, with carpet floors or isolating shoes. If such conditions are present special
care should be taken while manipulating HID modules. Operators, before even touching any components,
must make sure that their bodies are not charged by either touching a grounded surface or by using an
antistatic grounded wrist bracelet.
