Warning: Do not clean or disinfect while the device is in clinical use.

Warning: Always wear gloves while cleaning and disinfecting the device.

Warning: Do not service the device while it is in clinical use.

Warning: Always disconnect power prior to performing service or maintenance.

Warning: This device should only be serviced by authorized service personnel.

!

Warning: Allow the device to dry after cleaning and disinfection. Small amounts of flammable agents, such as glycol, ether, alcohol, or similar cleaning or disinfecting solvents left wet on the device can ignite.

!

Warning: Dispose of all waste properly as per federal, state, and local waste disposal regulations. Improper disposal could result in personal injury and environmental impact. Caution: Do not allow alcohol or substances containing alcohol, such as handdisinfectants, to come in contact with any acrylic part. Alcohol can cause clouding of acrylic parts. After using a hand-disinfectant, allow your hands to thoroughly dry before touching the device.

!

Warning: Using a device with a fan motor that has worn parts can produce unacceptable noise levels within the patient compartment.

!

Warning: Limit the load on the device on the outside of each upright to 18kg. Do not mount shelves to the outside mounting rail more than 137 cm from the floor.

Safety Information Safety and Regulatory Information

!

Warning: Overloading the shelves and rails can affect the stability of the device. Always try to evenly distribute the weight of options on both sides of the unit for a more balanced load.

!

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. Caution: Do not remove the compartment sensor mounted to the bed panel on the Control Panel end; the compartment sensor must remain in the correct position for proper operation.

!

Warning: A hazard can exist if different alarm settings are used with the same or similar equipment on a single patient. Caution: Pins of connectors identified with the Electrostatic Discharge Sensitive symbol should not be touched and connection should not be made to these connectors unless Electrostatic Discharge precautionary procedures are used. Caution: Do not mount or rest a radiant warmer or incandescent light on or over the device canopy; ineffective heating and damage to the canopy may result. If using incandescent phototherapy lamps, check manufacturer’s recommended minimum distance to canopy. Caution: Detailed information for more extensive repairs is included in the service manual solely for the convenience of authorized service personnel trained by General Electric having proper knowledge, tools and test equipment. Caution: Do not clean or disinfect the device with organic solvents, scouring compounds, strong acids, or strong bases. These compounds may damage components. Caution: Do not autoclave or gas sterilize any plastic parts unless stated otherwise in the manual.

!

Warning: Do not raise the incubator hood while the patient occupies the device. Raise the hood only for hood disassembly or cleaning. Caution: U.S. Federal law restricts this device for sale by or on the order of a licensed medical practitioner. Caution: This device is for professional use only.

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 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: 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.

!

Warning: Do not transport with storage drawer(s) open.

Caution: Do not move the device by pushing or pulling on the bed panels. This action may lead to the deterioration and breakage of these components. Caution: Do not place objects on the device legs.

Caution: To minimize the generation of static electricity, do not polish the side panels with a dry cloth.

Warning: Radiant warmers may increase a patient’s insensible water loss. Take appropriate measures to maintain the patient’s fluid balance while caring for them on a radiant warmer. Warning: Radiant energy can adversely affect blood components. When using intravenous tubing systems for delivery of blood components to patients occupying a device, limit the volume of a single transfusion to a quantity that can be infused within four hours or per clinical protocol.

!

Warning: Radiant energy may cause more rapid urine evaporation, and may lead to inaccurate urine diagnostic test analysis and inaccurate diaper weight measurements. Frequent measurement of urinary output is recommended.

!

Warning: Use Baby Mode unless Manual Mode is specifically prescribed. Always monitor the patient with the skin temperature probe and an independent thermometer device.

!

Warning: Do not place objects in the radiant heat path. Objects will be heated and could block heat to the patient.

Service Manual

Warning: Use of electrosurgical units or other electrical field radiating equipment can affect the operation of the device. Keep the patient probe lead as far away as possible from electrosurgical cables. Do not allow excess electrical cables to be laid on the bed platform. Use of electrosurgical units or other instruments that radiate electrical fields can cause indirect heating, by several tenths of a degree of the skin temperature probe due to absorbed electrical energy. When using these devices near the radiant warmer, operate the device in Manual Mode for maximum safety and use a skin temperature probe to monitor patient temperature. For added safety, you should consider use of the skin temperature alarm found in the Setup menu.

Warning: Do not place patient under radiant heat during Warmup Mode. Warmup mode is used to quickly warm and maintain heat in an empty bed. Warmup mode is not designed for clinical use with a patient due to the fact that the Check Baby Alarm is disabled. Warning: The heater, lamps, and surrounding areas are hot when in use and for 30 minutes after power down. Warning: Do not use a mercury thermometer while device is in use.

Warning: Do not place the patient in the bed during Warmup mode.

!

Warning: Once the patient is admitted, do not keep the device in Manual mode at 100% power for extended periods of time.

!

Warning: Observe the patient frequently, looking for signs of heat stress such as skin redness, warmth to touch, diaphoresis, or increased heart rate.
