Any loss of electrical function should be investigated with the following steps:
1. Make sure that all cords are plugged in, including pendant, staff control cords and AC Power.

was operating continuously, the motors may stop functioning for a short period of time to allow them
to cool. Full function will resume in less than 15 minutes.
