dinamap pro 1000 monitor error hw26631

Hi

I've got an older model Dinamap pro 1000 patient monitor and about once a day, it gives a loud blaring alarm and shuts down and needs to be rebooted. In the logs, it says, error HW26631, and I was able to find this explanation for the code: "operating system 300 hertz timer re-entry error."

Does anyone know how to repair this and if it can be repaired?

thanks

Tom
