SECTION 1: GENERAL INFORMATION WARNINGS
OBSERVE BEST PRACTICE: The instructions in this manual in no way supersede established medical procedures or staff preference concerning patient care.
ENSURE UNIT IS PROPERLY GROUNDED: To ensure grounding reliability, only connect the power cord to a properly grounded, 3-wire hospital grade outlet of the proper voltage and frequency. DO NOT USE EXTENSION CORDS. If the integrity of the connection is in doubt, the incubator should be operated from its internal battery.
EXPLOSION HAZARD: Do not use the examination light, the pulse oximeter, or oxygen monitor in the presence of flammable anesthetics or other flammable gases.
USE OF OXYGEN INCREASES FIRE DANGER: Spark-producing auxiliary equipment should not be placed in or near the transport incubator.
Avoid direct sunlight or radiant heat, which can cause a dangerous increase in chamber air temperature.
Avoid eye exposure. Direct light exposure may cause eye damage. Infants must wear eye protection.
The use of oxygen may increase the noise level within the infant chamber.
Air and oxygen tanks are pressurized and must be properly secured.
The transport incubator is Type B equipment and the baby may not be electrically isolated from earth. Care must be taken that additional equipment connected to the baby is electrically safe. To ensure patient electrical isolation, connect only to other equipment with electronically isolated circuits.
Do not change the lamp and touch the patient simultaneously.
When the infant tray is removed, do not touch exposed circuitry and patient simultaneously.
This incubator was calibrated with the infant chamber originally supplied. If this chamber is exchanged for an infant chamber of a different configuration or size, the temperature calibration will be affected. Consult International Biomedical before returning the incubator to service.
The incubator should be turned off and AC or DC power disconnected when cleaning.
Part No. 715-0079, Rev. B

SECTION 1: GENERAL INFORMATION
The use of devices which radiate high intensity electrical fields may affect the operation of the transport incubator. Constant assessment of the patient and all life support equipment is mandatory whenever interfering devices are operating on or near patient.
When using the transport incubator adjacent to or stacked with other equipment, observe the operation of the transport incubator and the other equipment to ensure normal operation.
Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer then 30 cm to any part of the transport incubator and associated cables. Otherwise, degradation of the performance of this equipment could occur.
When the incubator is attached to a Ferno 146 Collapsible Cart, the two highest positions should not be used as they can cause a tip hazard.
Do not use the pulse oximeter or oximetry sensors during magnetic resonance imaging (MRI) scanning. Induced current could potentially cause burns. The pulse oximeter may affect the MRI image and the MRI unit may affect the accuracy of the oximetry results.
If using pulse oximetry during full body irradiation, keep the sensor out of the irradiation field. If the sensor is exposed to irradiation, the reading might be inaccurate or the unit might read zero for the duration of the active irradiation period.
The pulse oximeter should NOT be used as an apnea monitor.
If an alarm condition (other than exceptions listed herein) occurs while the MUTE button is activated, only visual alarm indicators will be activated.
Pulse rate measurement is based on the optical detection of a peripheral flow pulse and therefore may not detect arrhythmias. The pulse oximeter should not be used as a replacement or substitute for ECG based arrhythmia analysis.
Connecting equipment to the outlets on this device creates a medical electrical system and the user is responsible for continued compliance with the requirements of IEC 60601-1.
Do not modify this equipment without proper authorization from International Biomedical.
An Infant Transport Incubator should be used by appropriately trained personnel and under the direction of qualified medical staff familiar with currently known risks and benefits of Infant Transport Incubator use.

POWER FEATURES The incubator can be operated in one of three power modes: external AC power, external DC power, or internal battery power. AC Power Mode AC power can be supplied using either 120 V or 230 V external AC power, depending on the incubator configuration. When operating in AC power mode, the AC OP indicator (Figure 2 - 1, item 29) will be illuminated. AC power has priority over all other power sources, external or internal. AC power should be used for warming the incubator in preparation for transport and must be used to recharge the battery. WARNING:
ENSURE UNIT IS PROPERLY GROUNDED: To ensure grounding reliability, only connect the power cord to properly grounded, 3-wire hospital grade outlet of the proper voltage and frequency. DO NOT USE EXTENSION CORDS. If the integrity of the available external power sources is in doubt, the incubator should be operated from its internal battery.
Part No. 715-0079, Rev. B
- 16 -
SECTION 2: OPERATING INSTRUCTIONS DC Power Mode DC power can be supplied using a 12 V power source. When operating in DC power mode, the DC OP indicator (Figure 2 - 1, item 30) will be illuminated. External DC power is supplied through a 3 conductor circular connector located on the back of the incubator (Figure 2 - 2, item 5). DC power has priority over internal battery power. While operating in DC power mode, the battery will not be charged. Battery Power Mode Battery power will automatically be selected when neither AC power nor DC power are available. When operating on internal battery, the BAT OP indicator (Figure 2 - 1, item 31) will be illuminated. Connecting AC or DC power will supersede battery power operation. The battery charger operates continually when the incubator is connected to an AC power source. When charging, the green BAT CHG indicator (Figure 2 - 1, item 28) will be illuminated. The rate at which the battery charges decreases when the incubator is powered on. A significantly low AC line voltage will also decrease the rate of battery charge. It takes approximately 8 hours to fully charge a completely discharged standard 26 ampere-hour battery when the incubator is supplied AC power and is powered down. If the incubator is on and warming up, the battery charge time is two to three times longer. The incubator will maintain an infant chamber temperature of 37 C for three hours on a fully charged battery with an ambient temperature of 20 C. NOTE:
When not in use, the incubator should be plugged into an AC source to recharge the battery. See SECTION 5 on BATTERY CARE.
To determine how much battery life is left, the Battery Life Display Button (Figure 2 - 1, item 26) can be pressed to display the status of the battery on the Main Display Screen (Figure 2 - 1, item 8). In this mode, the Battery Life Display Indicator (Figure 2 - 1, item 12) will be illuminated. When operating on AC power, the Main Display Screen will indicate the state of charge of the battery as an estimated percentage (to the nearest 20%). A fully charged battery will display 100% and a battery which has almost reached its safe discharge level will display 0%. When the incubator is operating from battery power or external DC power, the Main Display Screen will indicate the battery voltage (to the nearest 0.3 volt). Regardless of the power source, error code E03 will be reported if the battery voltage is outside of the 9.0 volt to 14.5 volt range. To continue normal operation, the battery voltage must be above 10 0.3 volts. For general operation, the use of external AC or DC power is HIGHLY RECOMMENDED. The internal battery should be used only when the incubator has no other energy source available. Part No. 715-0079, Rev. B
- 17 -
SECTION 2: OPERATING INSTRUCTIONS Power Interruption / Failure If external AC or DC power is lost while the incubator is powered on, the incubator will automatically switch over to battery power with no interruption in incubator performance or degradation of pulse oximeter and/or oxygen monitor accuracy. In the event of total power loss, all user-programmed settings (e.g. temperature setpoint, alarm limits) will default to the most recently programmed values.
POWERING UP THE INCUBATOR To turn the incubator on, press the Power Button (Figure 2 - 1, item 32) on the lower right hand corner of the Front Display Panel. When the incubator is turned on, all functional LEDs on the display panel will illuminate and the audible alarm will sound. This Power-up Indicator Test will last approximately two seconds after which the Main Display Screen will display the infant chamber air temperature set point. The PulseOx Display screen will alternately display the HI/LO alarm settings for 16 seconds. To interrupt the PulseOx display, press the PulseOx settings button. After the initial start-up, the PulseOx display will be in the “Off” status. After 5 seconds, if no buttons have been pressed, the display will change and show the actual measured infant chamber air temperature. The incubator will immediately attempt to regulate the infant chamber air temperature to the last set point stored in memory (refer to SECTION 2, SETTING THE INFANT CHAMBER AIR TEMPERATURE, for instructions on setting the temperature). One of three power source indicators will be illuminated, indicating which source is currently powering the incubator.
AC power indicator (Figure 2 - 1, item 29)
External DC power indicator (Figure 2 - 1, item 30)
Internal battery power indicator (Figure 2 - 1, item 31)
POWERING OFF THE INCUBATOR To turn the incubator off, press the Power Button (Figure 2 - 1, item 32) on the lower right hand corner of the Front Display Panel. The Power Button provides the means of electrically isolating the incubator circuits from supply mains simultaneously on all poles.
