4. Gently pull the ear back to straighten the ear canal and snugly position
the probe into the ear canal, aiming towards the membrane of the
eardrum to obtain an accurate reading ( Fig.4-1)
5. Measuring the ear temperature: Use the index finger to hold the “Scan” button (located other side of
LCD display at the top) down until you hear a beep ( Fig. 4-2 ).
6. Remove the thermometer from ear, the temperature reading will display
on LCD screen.

This ear thermometer can store up to 9 readings. The memory function allows you to make temperature
comparisons for evaluation of temperature trends.
Using Memory Function
1. If the reading of the thermometer is within the normal temperature range of 93.2
o
F to 108.0
o
F (34
