repair is required, contact someone in the facility immediately. DO NOT use the
equipment until the facility has verified that the equipment is working properly.

securely tightened, connected, and functioning properly. Pay particular attention
to the condition of cables and cable ends. If you notice a loose cable end or any
fraying of the cable or cable jacket, DO NOT use the product and contact
someone in the facility immediately.
