This product uses UV light to detect residues. For safety reasons, this product does not contain any anti-yellowing agents, therefore prolonged exposure to the UV lights it emits may cause the certain parts of this device to turn yellow after time. This is completely natural and does not affect the functions of the device, nor cause harm to humans. This product uses UV light detection, therefore before opening the bottom cover or cleaning the device, ensure that the device is powered off or in Standby mode and make sure not to look directly into the light source. Please seek medical help immediately if you feel uncomfortable. Fruit and Vegetable test list Description Rich in phytochemicals (Chlorophyll /

Anthocyanin); colorants are released in large amounts when washing these fruits and vegetables. This may affect the test results. Fruits and Vegetables not applicable to the test results

(Including but not limited to:) Okinawa Spinach, Red Amaranth, Strawberry Rich in phytochemicals or plant spores, which are released in large quantities when washed and may affect the test results. Mushrooms, Cloud Ear Fungus, Seaweed, Enoki Mushroom

Place the PureGo onto the charging dock with the front side facing outwards.

(The side with the ASUS logo is the front side of the PureGo; the side with the model name and certifications is the rear of the PureGo.) 2. Connect the cable from the charging dock to the USB power adapter. 3. Plug the USB power adapter into a power outlet. NOTE:

Ensure to wait until your PureGo is fully charged before using it for the first time. Your PureGo is fully charged when the LED ring lights up green. This device uses a power adapter with a power input of 5V/2A. Ensure to use the bundled power adapter when charging the PureGo. 9 PureGo User Manual Calibrating your PureGo CAUTION!

Ensure to follow the calibration tutorial and calibrate when using your PureGo for the first time. You do not need to calibrate after every use, but we recommend calibrating your PureGo periodically (once every 1 to 3 months, depending on usage frequency) to ensure detection accuracy. We recommend recalibrating when changing usage locations to ensure detection accuracy. There may be slight differences in the water quality of the same area during different times. We recommend calibrating periodically, or calibrating when the PureGo APP reminder appears. To Calibrate your PureGo:

1. Press and hold the Start/Standby button for approximately 1.5 seconds until the LED ring lights up blue, then place your PureGo into clean water. Belt CAUTION! To ensure the optical detection chamber is completely immersed in the water, the belt should be below water level when your PureGo is placed into the water. 2. The LED ring will blink blue during calibration. When the calibration process is completed, the LED ring becomes a solid blue light. The calibration process should take about 25 seconds. 10 PureGo User Manual Detecting with the PureGo when washing fruits or vegetables PureGo's revolutionary smart water detection feature allows instant detection of the amount of pollutants in the water once it is placed in the water. When the LED ring begins blinking orange, we recommend continuing with washing the fruits and vegetables, or changing the water and soaking the fruits and vegetables again. When the LED ring blinks green, the cleanliness of the water is close to clean water. NOTE: For more information on the LED descriptions, please refer to the table on page 7. Recommended washing steps 1. Clean the surface of the leafy parts and dirt from the roots of the fruits and vegetables using clean water or with a tool. 2. Soak the fruits and vegetables in clean water for approximately 1 minute to allow agricultural pesticide or other residue such as dust to dissolve in the water. PureGo's revolutionary smart water detection feature makes it so that no buttons have to be pressed during the detection process; PureGo will automatically begin detection once it is placed in the water. CAUTION! To ensure the optical detection chamber is completely immersed in the water, the belt should be below water level when your PureGo is placed into the water. Belt 11 PureGo User Manual 3. Continue washing the fruits and vegetables with a small trickle of water to wash away agricultural pesticide or other residue on the surface of the fruits and vegetables, while continuing the detection process with the PureGo. 4. The cleanliness is indicated by the LED ring on PureGo:

Red (blinking): Lots of pollutants / impurities detected in the water, please change the water or continue washing thoroughly. Orange (blinking): Medium amount of pollutants / impurities detected in the water, we recommend continuing with washing the fruits and vegetables. Green (blinking): Low amount of pollutants / impurities detected in the water; the cleanliness of the water is close to clean water. You can stop washing. 5. Remove the inedible parts of your fruits and vegetables. NOTE: A short press on the Start/Standby button will start/end this session. 12 PureGo User Manual Notes when washing fruits and vegetables:

Please follow the recommended procedures and recommended water temperature (8C

~ 35C) when using PureGo to avoid detection abnormalities. This device is made to function in clear water. Do not use the device in other non clear water aqueous solutions such as sodas, tea, or coffee. Clear water is the best solution when washing fruits and vegetables. We do not recommend using commercial fruit and vegetable wash solutions, salt water, baking soda, or vinegar as it may not be able to remove agricultural pesticide, and may even prolong the degradation time of the agricultural pesticide, increase the chances of chemical contamination of the fruits and vegetables, or result in detection abnormalities. Take care not to damage the surface of the fruits and vegetables when washing them, as an excess of phytochemicals in the water may affect the detection accuracy. If you find damages or bruises on the fruits and vegetables when washing them, we recommend removing them from the water used for detection and rinsing them each individually. This device is used to assist with the washing of common fruits and vegetables. Do not wash items that may contaminate the water such as tea leaves or herbal medicine. Cooked food cannot be used with the detection feature of this device. If your LED ring lights up red due to an error while washing the fruits and vegetables, please refer to the following for help:
