The probe head needs to be carefully protected.2. Please gently wipe the surface of the meter.3. Do not use corrosive cleaners.4. Do not clean the product in water or other liquids.5. Put this product in a dry place to reduce dust, pollution and sunlight.LCD cannot display the value1. If in the state of animal measurement, when the temperature is lower than 32C or higher than 45C, the LCD will not display the value but will display "LO" or "H".LCD display information "HI"When using non-contact infrared temperature, LCD displays the message "HI"The surface of the analyzed animal is above 45C.LCD displays the message "LO".When using non-contact infrared temperature. LCD display information "LO"The animal temperature was below 32C when analyzing the meter..Package List:1 x Animal Thermometer(Battery Not Included)1 x Instruction ManualNote:1. The measurement is too far away from the animal, within 5CM.2. When measuring, find a place where there is no hair, like the edge of the ear, or inside the ear. If there is hair, it will be the temperature of the hair, not the temperature of the skin.3. When testing, the animal should be still and not running.4. Please install the battery before use.
