Note: All work on Electric FIREFLYs needs to be done taking static grounding precautions. Failure to use a grounded
static mat and wrist strap when handling or retrofitting the FIREFLY to an electric meter could result in static discharge
damage to the electronics. Units found to be damaged in this manner will not be covered by Datamatic warranty. See
