Action

Consignees were to receive a recall notice by mail dated 06/30/2017. The notice identifies the reason for recall and goes on to instruct consignees to run verification tests on units to ensure they are operating properly. Only applicable tests should be performed on the unit. If the unit passes verification tests, then the attached acknowledgment form is to be signed and returned to Elekta. If the unit fails verification, consignees are instructed to contact their local Elekta Care Support Center for assistance. If a unit is no longer in use, consignees are asked to sign and return the acknowledgement form, noting that the unit is no longer in use. The firm asks that the recall notice be placed in an accessible area to users until the field action is closed. Appropriate personnel should also be provided the content of the recall notification.
