As technology advanced, we have kept the Warmer simple & easy to use with one touch controls. The heater with reflector makes it easier to work with the baby by efficiently providing even heat distribution across the cradle and not into the surrounding environment. Air control is an electronic feedback system which functions as a thermostat to maintain a constant temperature of baby cradle by regulating the heat output of Radiant Warmer. It Also acts as a WATCH DOG as Air over temperature cuts off heater even if the Warmer is operating in Servo mode. The Manual mode allows the Warmer to be kept ‘baby ready’ without nuisance alarms. When needed the Warmer provides safe, powerful& controlled warming to restore the temperature drop experienced by the baby immediately after delivery.
