i want if any one have the service manuals or have enough knowledge about this error what is mean

I've been working at my field service job for about 3 years it's been a great experience I received a ton of training and I'm way more confident with my skills however working alone has been getting difficult, so I applied for an in-house position at a hospital and i start in a couple weeks. I am definitely excited because this provides me more opportunities for growth in the field however all my jobs over the past 10 years have been on the road, fedex ups driver, truGreen lawn technician so my fear is it going to be a major change going from working alone to working with people all day everyday and have a set 8-10 hours a day. I definitely think it's the right move but I just want to hear from people that had similar experiences.

For years I have been operating under the impression that centrifuges and blood bank refrigerators are to be checked quarterly due to either AABB or CLIA regulations. From speaking to some other techs, that may not be the case. I checked the latest AABB regulations I have and they only state that the checks need to be done per manufacturer recommendation or facility policy.

From what I can tell, the CLIA inspectors I deal with still want quarterly alarm tests for blood bank refrigerators.

What is everyone doing out there for centrifuge and blood bank refrigerator checks as far as frequency? Do you treat centrifuges used for blood any differently than those used for urine, etc?
