  If the 3M Medical Equipment warming unit's alphanumeric display flashes a temperature of 43°C (Model 245) or 48°C (Model 247) or higher, along with the word “HI,” and the alert indicator illuminates with a sound, consider these possibilities: * If an extreme change in flow rates occurred, open the flow to reduce the temperature. The alerts will stop when the display reads 41°C, and the unit will be ready to use. * If the unit reached the set point temperature before the cassette was inserted, the alerts will stop when the display reads 41°C, making the unit ready for use. * If fluids were prewarmed above 42°C, turn off the unit, discontinue the infusion, and avoid prewarming fluids before using the Ranger warming unit.

  If the 3M Medical Equipment warming unit's alphanumeric display flashes a temperature of 33°C or below along with the word “LO,” and the alert indicator illuminates with a sound, the alert should stop when the temperature rises above 33°C. This under-temperature condition may be caused by very high flow using very cold fluid, or a defective heater/relay. If the alert continues, turn off the unit, unplug it, and discontinue use.
