How to fix a Digoo DG-PC809 that failed to power on?
If your Digoo Thermometer doesn't power on, it might be due to a few reasons. First, the battery level could be too low, so try replacing the batteries with new ones. Second, check if the polarities of the batteries are reversed and ensure they are mounted correctly. If neither of these steps works, the thermometer might be damaged, and you should contact the dealer or manufacturer.
Why is my Digoo DG-PC809 reading too high?
An inaccurate high reading on your Digoo Thermometer can occur for several reasons. If you've just come from a hot environment or have been exposed to hot air from an air conditioner or heater, wait at least 30 minutes in a room between 10.0°C/50.0°F and 40.0°C/104.0°F before taking your temperature. Also, low battery can cause this issue, so replace the batteries.
What to do if my Digoo DG-PC809 reading is too low?
If your Digoo Thermometer shows a reading that seems too low, there are a few potential causes. The infrared sensor lens of the probe may be dirty; clean it with cotton swabs dipped in anhydrous ethanol. Also, ensure the probe is close enough to the target; for forehead readings, the probe should cover or touch your forehead, or be placed in your ear canal. Finally, if you've just come from a cold environment, allow yourself to acclimate in a room between 10.0°C/50.0°F and 40.0°C/104.0°F for at least 30 minutes before measuring your temperature.
What does Err mean on my Digoo DG-PC809?
The 'Err' message on your Digoo Thermometer indicates that the environment temperature is not within the range of 10°C to 40°C (50°F to 104°F). First, ensure the probe is clean. If the environment temperature is out of range, both the patient and thermometer should be in a room between 10.0°C/50.0°F and 40.0°C/104.0°F for at least 30 minutes before taking a temperature measurement. If the problem persists, contact the dealer or manufacturer.
What does 'Hi' mean on my Digoo Thermometer?
If your Digoo Thermometer displays 'Hi', it means the measured human body temperature is over 42.9°C/109.2°F. First, make sure the probe is clean. If the environment temperature is out of range, both the patient and thermometer should be in a room between 10.0°C/50.0°F and 40.0°C/104.0°F for at least 30 minutes before taking a temperature measurement. If the problem persists after trying the above method, please to contact the dealer or manufacturer.
What does 'Lo' mean on my Digoo DG-PC809?
If your Digoo Thermometer displays 'Lo', it indicates that the measured human body temperature is below 32.0°C/89.6°F. First, make sure the probe is clean. If the environment temperature is out of range, both the patient and thermometer should be in a room between 10.0°C/50.0°F and 40.0°C/104.0°F for at least 30 minutes before taking a temperature measurement. If the problem persists, contact the dealer or manufacturer.

The DIGOO DG-PC809 is a medical infrared thermometer designed for measuring human body temperature by detecting infrared energy emitted from the forehead or the eardrum. This versatile device offers two primary measurement modes: forehead mode, suitable for people of all ages, and ear mode, recommended for individuals over three months old. The thermometer is designed for quick and accurate readings, providing results in approximately one second.
The thermometer operates on the principle of collecting infrared energy emitted from either the eardrum in the ear canal or the skin of the forehead. This infrared energy is then focused by a lens and converted into a temperature reading by thermopiles and measurement circuits.
The DG-PC809 model provides a 'beep' cue at the end of a temperature measurement. The DG-PC809E model broadcasts the temperature in English via speakers, while the DG-PC809V model emits vibration feedback at the end of a measurement. Beyond these specific feedback mechanisms, the intended use and core functionality of all three models are identical.
The device is equipped with an intelligent alarm system. An orange LED lights up to indicate a low fever, while a red LED illuminates for a high fever. These thresholds are preset but can be adjusted by the user to suit individual needs after consulting a doctor. The low fever alarm is initially set at 37.5°C/99.5°F, with an adjustable range from 37.5°C/99.5°F to 37.9°C/100.2°F. The high fever alarm is preset at 38.0°C/100.4°F, with an adjustable range from 38.0°C/100.4°F to 38.9°C/102.0°F.
The DG-PC809 is designed for ease of use with a one-button interface for power, measurement, and settings.
To take a forehead temperature:
To take an ear temperature:
The thermometer can store up to 32 sets of measurement data. When the memory is full, the oldest reading is replaced by the newest. To recall memories, press and hold the setting button for about 3 seconds from shutdown until the 'M' symbol flickers. Subsequent presses of the button will cycle through the stored temperature values.
The device supports conversion between Celsius (°C) and Fahrenheit (°F). From shutdown, press and hold the Setting button for about 6 seconds until the 'C' or 'F' symbol flickers. Releasing and pressing the button again will toggle between the units.
Users can turn the buzzer, speaker, or vibration function on or off. From shutdown, press and hold the setting button for about 9 seconds until 'ON' or 'OFF' appears on the screen. Release and press the button again to toggle the function.
The thermometer automatically shuts down after 30 seconds of inactivity to conserve energy. Alternatively, it can be manually turned off by holding the Power button for 5 seconds.
The device is powered by two AAA dry batteries. A low battery indicator will appear on the screen when the voltage drops below 2.6V±0.1V, signaling that the batteries need replacement. To replace them, slide off the battery cover, remove the old batteries, and insert two new AAA batteries according to the marked polarity.
Regular cleaning and disinfection are crucial for maintaining the thermometer's accuracy and hygiene. For cleaning the thermometer body:

Storage guidelines:
The device is designed with high-precision parts, so it should be protected from severe impact or shock. Do not twist the instrument or the infrared sensor. If any signs of damage appear on the infrared sensor lens or the instrument itself, do not attempt to repair it; contact the dealer or manufacturer.
