Before working in any GE Healthcare MR suite or performing any GE Healthcare service procedure, you must:

  • Have read and understood all hazard conditions and safety requirements in the latest revision of the GE Healthcare MR Service Safety Manual (5452735).
  • Have successfully completed all relevant GE Healthcare Environmental Health and Safety (EHS) courses (or for non-GE employees, equivalent workplace training courses).
  • Comply with all site-specific training and workplace safety requirements.

If you have any safety concerns at any time, do not begin work or immediately stop work and move to a safe location. Immediately contact your supervisor or site safety officer for instructions on how to proceed.

About this task

An error indicates an issue in the E-Stop circuitry. The E-Stop circuit, when activated, will remove power from Gradient, RF, and patient handling components until it is manually reset by pressing the EMO Reset button on the front of the PDU. A message indicating that the system is in EMO Reset state will also be posted to the system message log.

Troubleshooting the E-Stop circuitry consists of three functional areas: Equipment Room, Scan Room, and Operator Room.
