Ear Temperatures
Spot LXi with the Braun ThermoScan PRO 4000 thermometer takes a temperature in the 
ear. The thermometer probe shape prevents insertion far into the ear canal which could 
perforate the tympanic membrane.
To take an ear temperature reading:
1. Pull the bottom of the thermometer gently toward you to remove it from the housing.
2. Locate the probe cover box inside the thermometer housing. Firmly push the probe 
tip into the probe cover box. When the probe cover is in place the thermometer turns 
on automatically. 
3. Listen for the ready signal beep and three dashes to appear on the thermometer 
display.
4. Fit the probe snugly into the ear canal and then push the Start button. 
a. If the probe is positioned correctly in the ear canal the «ExacTemp» light flashes. 
When the thermometer detects an accurate measurement, the «ExacTemp» light 
is continuously on, a long beep signals the end of the measurement, and the 
display shows the result.
b. If the probe is positioned incorrectly in the ear canal or is moved during the 
measuring process, the «ExacTemp» light goes out, a sequence of short beeps 
sounds, and the display shows an error message («POS» = position error). 
5. Press the ejector button to eject the used probe cover into the trash when you are 
finished taking the temperature.
6. Return the thermometer to its holder. Spot LXi displays the patient’s temperature and 
temperature scale in the Temperature Display area on the LCD (see “Display 
Window” on page 24). 
WARNING Keep the probe window clean, dry, and undamaged at all times to 
ensure accurate measurements. To protect the probe window, always keep the 
thermometer in the storage cover while transporting or when not in use.
WARNING Only use Braun ThermoScan probe covers with this thermometer. 
Using other manufacturer’s probe covers or no probe cover may produce 
temperature measurement errors and/or inaccuracies. If the thermometer is used 
without a probe cover attached, clean the lens (see “Braun ThermoScan PRO 
4000 Thermometer” on page 64).
WARNING Do not autoclave.
WARNING The thermometer is not waterproof. Do not immerse or drip fluids on 
it. Should this occur, dry the thermometer with warm air. Check for proper 
operation and accuracy.
