are emitted. If the measured temperature is above 42.2 °C (108 °F),
“Hi” appears on the LCD display and four short acoustic signals are
emitted.
Note
If you keep getting di erent measurement results, you should measure
the temperature in the test mode.
To measure the temperature in the test mode proceed as follows:
•
During the measurement hold down the start button ( ) for three
seconds.
•
Twist the measuring probe from side to side while taking the meas-
urement to register the whole auditory canal or fi nd the highest tem-
