READ AND SAVE THESE INSTRUCTIONS IMPORTANT SAFEGUARDS Follow basic safety precautions when using your smart air fryer toaster oven. Read all instructions. Key Safety Points • Do not touch hot surfaces. Use handle. • The outside of the oven, including the door, is hot during and after use. • Always use heat-resistant gloves, pads, or oven mitts when handling hot materials, and when placing items in or removing items from the oven, including trays, racks, accessories, or containers.
• This oven is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the oven by a person responsible for their safety. • Do not allow children to clean or perform maintenance on the oven. • Keep the oven and its cord out of reach of children. • Not for commercial use. Household use only.
Power & Cord Extension Cords • This oven uses a short power-supply cord to reduce the risk of entangling or tripping. • Your oven has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not alter the plug in any way. • Do not let the power cord (or any extension cord) hang over the edge of a table or counter, or touch hot surfaces.

These will scratch or damage their surfaces.
TROUBLESHOOTING Problem Possible Solution The oven will not turn on. Make sure the oven is plugged in. Food is not completely cooked. Increase cooking temperature or time. Decrease cooking temperature or time. Food is overcooked or burned. Make sure food items are not too large and are not touching the heating elements. Food is cooked unevenly. Make sure food items are not too closely packed into a tray, rack, or other container. The oven may produce some white smoke or steam during cooking.
VESYNC APP TROUBLESHOOTING Problem Possible Solution During the setup process, you must be on a secure 2.4GHz Wi-Fi® network. Confirm that the network is working correctly. Make sure the Wi-Fi® password you entered is correct. Why isn’t my oven connecting to the VeSync app? Turn on Bluetooth® on your phone (for Android™ users, make sure Location is turned on as well). Make sure your oven and phone are within 30 ft / 10 m of each other.
