is displayed, please refer to the

“TROUBLESHOOTING” section for details to correct the

problem.

2. Apply the thermometer to the measurement site.

Use the oral, rectal or underarm site for measurement.

NOTE:

Even if the “L” indicator fails to display (when only the

temperature is displayed), this is not an error. So the

temperature may be taken as is.

3. When the reading is ready, the thermometer will emit a

[beep-beep-beep] sound three times. Remove the

thermometer from the measurement site and read the

result.
