CAUTION
Electrostatic discharge can damage or cause the failure of semiconductor devices such as integrated
circuits and transistors. The symbol at right may appear on a circuit board or other electronic assembly
to indicate that special handling precautions are needed.
• A properly grounded conductive wrist strap must be worn whenever an electronics module or circuit board is
handled or touched. A service kit with a wrist strap and static dissipative mat is available from Siemens
(PN15545-110). Equivalent kits are available from both mail order and local electronic supply companies.
• Electronic assemblies must be stored in anti-static protective bags when not installed in equipment.
