The manufacturer's technical support specialist verified the reported complaint.During laboratory analysis, the product surveillance technician (pst) duplicated the reported complaint.He observed the fraction of inspired oxygen (fio2) knob was tight against the metal front panel of the epgs causing mechanical binding of the fio2 knob.This likely caused by unintentional inward bump of the knob and failure of the knob would cause the error message that was displayed.The product will be sent to service to be brought to manufacturer¿s specifications before being returned to the customer.If additional information becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be filed accordingly.
