The bed also has control circuitry coupled to the lift system to 5 command operation of the lift system. The control circuitry further includes an angle sensor to provide a signal indicative of an angle at which at least one of the base and the upper frame are tilted away from a substantially horizontal orientation. The control circuitry has an indicator that is activated to indicate to a caregiver that the lift system should be operated to move the upper frame to the low position when the 10 angle sensor indicates that the angle is greater than a threshold amount.
