Siemens recommends specific preventive maintenance (PM) intervals. The service manual details:
This is the most referenced section of the manual. For example: acuson s2000 service manual
It is critical to differentiate between the Acuson S2000 User Manual (for sonographers) and the Service Manual (for engineers). | Feature | User Manual | Service Manual
| Feature | User Manual | Service Manual |
| :--- | :--- | :--- |
| Audience | Radiologists, Sonographers | BMETs, Field Engineers |
| Content | Preset settings, measurement tools, patient data management | Schematics, voltage points, error codes, disassembly |
| Contains passwords? | No | Yes (Service login: levvrag / typical passwords) |
| Calibration data | No | Yes (Doppler flow phantom setups) | Sonographers | BMETs
Given that the S2000 is used in patient contact environments, the service manual includes leakage current test protocols (per IEC 60601-1). It specifies the exact resistance values for protective earth ground (less than 0.1 ohms) and touch current limits.
