Electromagnetic Compatibility
ESD with communication connectors In order to prevent operating malfunctions,
it is recommended, that the operating per-
sonnel discharge themselves prior to
touching communication connectors or
perform other suitable measures to reduce
effects of electrostatic discharges.
