Measuring Temperature
While in the forehead mode, a smil-
ing face “ ” will display to indicate a
temperature lower than 38°C (100.4°F). If
the temperature is equal to or higher than
38°C (100.4°F), you will see a frowning
face “ ” on the display, accompanied
by one long beep followed by two short
beeps (see Figures 7 and 8).
The LCD displays “Lo” or “Hi” when the
temperature measured is outside the ther-
mometer’s sensory range (see Figures 9
and 10).
“Err” appears if the operating temperature
is outside the permissible range of 16°C
to 35°C (60.8°F to 95°F) (see Figure 11).
After one minute without use, the device
automatically powers itself off to conserve
battery life.
