2. Scope
RCG and TCG cameras must be handled with utmost care to avoid damage to the image sensor. Follow the
instructions in this document to properly prepare RCG or TCG cameras for operation.
3. Safety notes
3.1. Electrostatic discharge (ESD)
Electrostatic charge builds up in the body when walking on carpeted floor. This can discharge when
touching metal objects like a door handle. Such ESD can damage electronic devices, especially when tools
or hands get in contact with connectors. We recommend measures to avoid damage by ESD:
• Unpacking: Remove the camera from its anti-static packaging only when your body is grounded.
• Workplace: Use a static-safe workplace with static-dissipative mat and air ionization.
• Wrist strap: Wear a static-dissipative wrist strap to ground your body.
• Clothing: Wear ESD-protective clothing. Keep components away from your body and clothing. Even if
you are wearing a wrist strap, your body is grounded but your clothes are not.
3.2. Sensor damage
Follow the instructions thoroughly to avoid damage to sensor and camera. Work in a dust-free environment
(class 100 or better) with humidity according to ESD requirements.
