- Polarizer Care: The polarizer is soft and easily scratched. Do not touch with anything harder than an HB pencil lead. If contaminated, exhale on the surface and gently wipe with a soft dry cloth.
- ESD Protection: Observe standard ESD precautions during handling and assembly. A relative humidity of 50%-60% is recommended.
Handling & Compliance
- The module is RoHS compliant.
- Observe standard ESD precautions during handling and assembly.
