One important test following OEM recommended maintenance procedures is checking the slip ring system. Each manufacturer has prescribed times documented in the maintenance manuals. Precautions must always be taken when working on any medical device. Extreme caution is necessary when testing the slip ring system.

Always disconnect hazardous voltage before testing--failure to do so may result in serious injury or death.

Additonal safety recommendations when working around the gantry:

- Do not wear loose clothing or jewelry. Clothing may get entangled in the rotating frame and jewelry may short out high voltage.

- Do not stand near the rotating frame when it is in operation when covers are not present. Make sure rotating drives are off.

- Do not stand near slip ring assembly while power is present and the covers are off. Always make sure power is off. High voltage components will retain a charge for a short period of time. You can always check supplies with your DVM to confirm safety.

- Always lock out and tag out at the main disconnect for optimal safety.

- Always use and follow procedures described in the OEM service manual when servicing any CT scanner.
