Section V — Instructions for Use
Peak Select System
The Genius™ 2 Tympanic Thermometer and Base uses the patented Peak Select System. This system is well known from our Genius™ Thermometer. It reduces technique errors by taking multiple readings and automatically selecting the most accurate temperature for display. Whereas the Genius™ only used 32 readings for Peak Select, the new and improved Genius™ 2 Tympanic Thermometer and Base uses 100 readings.
Genius™ 2 Tympanic Thermometer and Base is an ear canal thermometer for neonates, newborns, children, and adults.
Prior to the introduction of tympanic thermometry, patient temperatures were measured in the mouth (oral), in the rectum (rectal), or in special cases with an indwelling Swan-Ganz™* catheter (core). If a patient’s temperature was measured simultaneously with each of these methods, different absolute temperatures would be obtained. The Genius™ 2 Tympanic Thermometer and Base compensates for the average difference in temperature at each of these sites by adjusting the displayed temperature.
A checker / calibrator is available for this device. The device should be checked if it is dropped or if it is stored at less than -25°C or above 55°C.
“ASTM laboratory accuracy requirements in the display range of 37 to 39°C (98 to 102°F) for Infrared thermometers is ± 0.2°C (± 0.4°F), whereas for mercury-in-glass and electronic thermometers, the requirement per ASTM Standards E 667-86 and E 1112-86 is ± 0.1°C (± 0.2°F).”
The following equivalence modes are available on the Genius™ 2 Tympanic Thermometer and Base. Data is available from
Covidien llc on request.
Ear: In ear (EAR) mode, the display will indicate the absolute temperature without adjustment.
Oral: In oral (ORL) mode, the tympanic temperature is adjusted to display an oral temperature equivalent.
Oral Mode = Ear Mode + 0.60°C.
Core: In core (CORE) mode, the tympanic temperature is adjusted to display the core temperature equivalent.
Core Mode = Ear Mode + 1.04°C.
Rectal: In rectal (REC) mode, the tympanic temperature is adjusted to display the rectal temperature equivalent.
Rectal Mode = Ear Mode + 1.16°C.
The Genius™ 2 Tympanic Thermometer and Base utilizes a single use disposable probe cover during temperature measurement.
The probe cover was designed especially for use with the Genius™ 2 Tympanic Thermometer and Base. The use of probe covers produced by any company except Covidien llc will result in erroneous temperature measurement. In order to aid in infection prevention and control, always install a new probe cover prior to taking a temperature. The probe covers are contained in a cassette that is located in the thermometer base. To load a probe cover on the thermometer, firmly insert the probe tip into the probe cover. When installed on the thermometer, the probe cover membrane should be smooth with no holes, tears, or wrinkles.
After the patient temperature has been taken, eject the probe cover by pressing the eject button and then dispose of properly.

Thermometer Display Icons and Alarms
Thermometer operation is communicated to the user via the LCD display and an audible device contained inside the thermometer case. After the probe cover is installed or the batteries have been changed, the thermometer will perform a system reset. The thermometer will perform an internal test to verify that the system components are functioning properly.
If the display shows a system error 4 and the system error icon, the ambient conditions are changing too rapidly for the device to be used. Allow the device to equilibrate for 20 minutes before using.
If the display shows any other system error, then reset the thermometer by installing a probe cover. If the system error does not clear, then contact the factory for available service options. The applicable manufacturer addresses are located in Section XII,
The biotech function is used to select the operational mode of the thermometer and to verify the installed software version. All operational mode settings in biotech mode are stored in nonvolatile memory and retained through system power cycles, such as changing batteries. All factory calibration parameters are also stored in nonvolatile memory.
The factory default settings are shown below:
