4. When the threshold temperature for i-Thaw or FastThaw is reached, the channel status will
display the estimated temperature range for the needle shaft (Screen 4-20).
NOTE: The shaft temperature is displayed as a temperature range because tissue and
procedural variables will affect the temperature.
