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

without a probe cover attached, clean the lens (see “Braun ThermoScan PRO 
4000 Thermometer” on page 64).

 option with Masimo 
or Nellcor brand sensors and accessories, respectively. Using the wrong or 
unapproved sensors or cables may cause improper performance.
