7. Remove the probe after the temperature measurement is complete and firmly press 
the ejection button on the top of the probe to release the probe cover. 
8. Return the probe to the probe well and wash your hands.
Monitor Mode
Monitor Mode displays the temperature of the probe as long as the probe remains in 
place at the measurement site and remains within the operating patient temperature 
range. The patient’s temperature will reach final equilibrium in approximately three 
minutes in the oral and rectal sites and five minutes in the axillary site.
To take a temperature in Monitor Mode:
1. Verify that the correct probe (oral/axillary = blue ejection button or rectal = red 
ejection button) and matching probe well are installed (see “SureTemp Plus” on 
page 27).
2. Hold the probe handle with your thumb and two fingers on the indentations of the 
probe handle and withdraw the probe from the probe well.
3. Insert the probe into a probe cover and press the probe handle down firmly. The 
probe handle moves slightly to engage the probe cover. 
4. Take the patient’s temperature using the Normal Mode as previously described. Leave 
the probe in place after Spot LXi beeps and the temperature is displayed. 
5. Hold the probe in place for approximately 30 seconds after the temperature is 
displayed until the temperature display shows the Monitor Mode indicator.
6. Hold the thermometer in place for a total of three minutes for oral and rectal mode or 
five minutes for axillary mode. The thermometer will not beep to indicate a final 
temperature. 
7. Record the temperature before removing the probe from the site; the monitored 
temperature is not stored in memory for recall.
8. Remove the probe from the patient and firmly press the ejection button on the top of 
the probe to release the probe cover. 
9. Return the probe to the probe well to reset the thermometer to Normal Mode. 
Temperature Measurement Range Indicators
When Spot LXi detects a temperature out of the SureTemp Plus measurement range, it 
beeps twice and displays the exceeded temperature limit. A small arrow flashes to 
indicate whether the out-of-range temperature measurement is too high (up arrow) or too 
low (down arrow).
WARNING Long-term continuous monitoring beyond three to five minutes is not 
recommended in any mode.
Note
Spot LXi does not retain Monitor Mode temperatures in memory for recall.
