Planned maintenance service schedules
Specific customer requirements and/or your site environment may necessitate more or less frequent intervals for planned maintenance (PM) service. An agreement to perform PMs less frequently than these recommendations can be made with the understanding that a reduction of system performance may result.
To further enhance productivity, the PM procedures have been divided into four types:
- Type 1 – Safety and Regulatory
- Type 2 – Image Quality
- Type 3 – Other (System not available for patient scans)
- Type 4 – Other (System available for patient scans)
The PM matrices list all the PM procedures and the frequency they should be completed, according to schedules listed below. The schedules indicate the procedures that are performed during each visit. They also show the type (1 - 4) for each procedure. The services should be completed at the indicated intervals and should be performed only by qualified service personnel.
The PM service schedule lists all the PM procedures and the frequency they should be completed according to schedules A -D. The checks are on a sequential yearly schedule, for example A is the first three months, B is the second three months, etc.
| Schedule | Timeframe |
|---|---|
| A | 0 to 3 months |
| B | 4 to 6 months |
| C | 7 to 9 months |
| D | 10 -12 months |
| CAUTION | |
|---|---|
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. | |
