Manufacturer Reason for Recall |
Incorrect field size -- Products manufactured prior to 1999 may experience jaw field size errors during interlock resulting in potential mistreatment if a light field check is not performed. This problem is present in machines with serial numbers less than 3094, as they do not contain redundant sensors for jaw position.

Action |
The firm has sent consignees a Customer Safety Advisory Notice on August 7, 2007 informing them that a misplacement of the X and/or Y jaws can occur if interlock #51 Jaw Field Position is asserted and then cleared with the left-hand key rest. The firm recommends that if an interlock issue is encountered tha treatment of the patient be discontined until this issue is resolved. |
