The letter instructed distributors to examine inventory for affected units, complete and return the provided Distributor Response Form, arrange for the replacement of affected oxygen sensors, perform all preventive maintenance checks on NOxBOXi devices prior to distribution of units, ensure all applicable personnel are notified within the organization, notify all customers who have received affected units.
