Reason for Recall: The Dose Error Reduction System (DERS) can potentially give an incorrect recommended value for the pump infusion rate during the initial infusion setup. This is due to a specific key sequence when the override feature of the DERS drug limits is activated. A device malfunction can result in an increased risk of over-infusion or under-infusion if the infusion is started with this rate value. This can cause serious adverse health consequences, including death.

看到原本在廢料堆裡的另一片電源板，突然想到，如果沒DC輸出，那是不是會較好查修，用一般的Switching Power的概念下去查修，呵，掛上示波器，真的初級振盪電路就沒工作了，再量一下UC2842的VCC輸入，原本的18V只剩12V，應該是這問題吧，往回查看18V在哪衰掉了，結果查到C11電容怪怪的，解下來，只剩15u，換了一個後，UC2842電壓回升到15V，示波器掛上，有振盪訊號了，Ya..再量一下，DC 14.1V，應該是OK了，請同事拿去裝上試看看，OK。
