E.4  Function and Requirement 
The ultrasound gel warmer can heat the ultrasound gel to about 40±1°C at the most. 
When the gel is placed inside the warmer, the time it takes to heat from an ambient 
temperature of 18°C to 28°C should be no more than 0.5 hours. 
The ultrasound gel warmer can work continuously over 12 hours. 
NOTE:  1.  When the ambient temperature is higher than the required temperature of 
the warmer, the warmer does not function. 
  2.  The warmer can only heat one bottle of gel at a time.
