Valley Electronics Daysy Instructions For Use Manual page 17

Daysy ends the measurement with a grumble buzz
instead of beep-beep.
The measurement timed out and was not successful. Use these tips
and retake your temperature:
– Put the tip of Daysy all the way under your tongue. The tip must
be nicely surrounded by body tissue to get a good measurement.
– Close your mouth while measuring.
– After starting a measurement, do not take Daysy out of your mouth
until you hear a beep-beep.
– If you have a fever, Daysy may not accept the temperature.
