Solution
Breeze, water, sweating, cosmetic on forehead may affect
measurement.
Check deviation value setting. Defaulted value is 0.8° C.
While if the teasting environmental temp changes so enormously or
if the trmometer is used directly from high-temp object to very low-
temp one, the measurement difference will happen. The thermometer
should be kept in a relative stable environment for 10 minutes to get
heat balance before stating a new measurement.
Ensure measurement distance is 3 cm to 5 cm
Take out and reassemble battery
Check if the thermometer is under menu setup. In procedure of menu
setting, thermometer is unable to measure and therfore no response.
Take out battery and install battery again.
Check if beeper is switched off.
Check battery level or take out and install the battery again.
