Safety and Regulatory Information Warnings
!
Warning: Direct sunlight, phototherapy, other radiant heat sources, or heated mattresses can cause an increase in device and patient temperature.
!
Warning: Proper temperature control depends on continuous, unobstructed air circulation. Do not cover air circulation openings around the bed, as obstruction will result in loss of air circulation, loss of heat, and carbon dioxide buildup.
!
Warning: A hazard can exist if different alarm settings are used with the same or similar equipment on a single patient.
!
Warning: Do not raise the incubator hood while the patient occupies the device. Raise the hood only for hood disassembly or cleaning.
!
Warning: When bed panels are in an upright position, ensure that the bed panels are securely locked in place. Ensure all bed panels are secure prior to leaving the patient’s bedside.
!
! ! ! ! !
Warning: When using a chest tube drainage system, verify that the system has adequate floor clearance prior to transporting or activating the elevating base. Warning: Always set the brakes before placing a patient in the device. Warning: Do not leave the patient unattended while any bed panels are lowered or removed. Warning: Only use bed panels approved for this device. Warning: Do not leave the patient unattended when using the device.
!
Warning: Before raising or lowering the bed, check that there is adequate slack in tubing and leads and that no obstructions limit the range of motion.
!
Warning: Never place patient on the X-ray tray. The X-ray tray is located under the mattress.

Service Manual
Warning: When opening or closing bed panels or portholes, make sure that the patient, as well as, clothing, monitoring leads, tubing, and similar items are completely within the confines of the bed. Inspect all patient connected tubes or leads before and after sliding out, rotating, tilting, or raising and lowering the bed. Moving the bed can pull on leads and tubing, restrict gas or liquid flow, or move probes out of position.
Warning: Do not transport with storage drawer(s) open.
Warning: Tilting the mattress from its horizontal position can result in uneven heat distribution.
