7 Notes on Handling and Assembly
7.1.

Notes on Handling

When using this product, ensure safe design by heeding the following precautions.
1. Prevention of Electrostatic Discharge (ESD)
Event based sensors and other ICs can easily be damaged by static discharge. When handling these modules, takethe following measures to prevent static discharge.
(1) Either use non-chargeable gloves, clothes or material. Also use conductive shoes.
(2) Use a wrist strap when handling directly.
(3) Install grounded conductive mats on the floor and working table to prevent the generation of static electricity.
(4) Ionized air is recommended for discharge when handling Event based sensors.
(5) For the shipment of camera, use bag treated for the prevention of static charges.
2. Notes on storage and operating environments
Do not store or use the lens modules in harsh environments with high temperatures, high humidity levels, and highconcentrations of dust or in environments where condensation may form from moisture or dampness.
