9. Operational EMC Requirements
The operational EMC immunity requirements and emission limits for DISPLAYTECH modules are
provided in table 1: EMC specification for operational modules.
After a charge of 4kV, the display module is allowed to go down for 2 seconds and need to comeback
again. With 8kV the display module is allowed to go down and has to comeback after a reset.
