Setup

Operating Instructions
Dual-Zone Cooking with SYNC Function
The HotKing oven features two independent cooking zones, allowing you to prepare different foods simultaneously at varying temperatures and times. The SYNC function ensures both zones finish cooking at the same time.
- Independent Zone Control: Each zone (A and B) can be set with its own cooking function, temperature, and time.
- SYNC Feature: To use the SYNC function, set the desired cooking parameters for both zones. Press the SYNC button, and the oven will automatically adjust the cooking times so both zones complete simultaneously.

Maintenance and Cleaning
Regular cleaning ensures optimal performance and extends the lifespan of your HotKing Air Fryer Toaster Oven.
- Unplug and Cool: Always unplug the appliance from the power outlet and allow it to cool completely before cleaning.
- Removable Accessories: All included accessories (air racks, baskets, baking trays, rotisserie tools, divider, crumb tray) are dishwasher safe for convenient cleaning. For stubborn residue, soak in warm, soapy water before scrubbing.
- Interior Cleaning: Wipe the interior walls with a damp cloth and mild detergent. Avoid abrasive cleaners or metal scouring pads, as they can damage the non-toxic stainless steel interior.
- Exterior Cleaning: Wipe the exterior with a damp cloth. Do not use harsh chemicals or abrasive materials.
- Crumb Tray: Regularly remove and empty the crumb tray to prevent grease buildup and potential fire hazards.
Troubleshooting
If you encounter any issues with your HotKing Air Fryer Toaster Oven, please refer to the following common troubleshooting tips:
- Appliance not turning on: Ensure the power cord is securely plugged into a working electrical outlet. Check your household circuit breaker.
- Food not cooking evenly: Ensure food is arranged in a single layer in the basket/tray. Avoid overcrowding. For best results, flip or shake food halfway through cooking. Verify correct temperature and time settings for the selected function.
- Excessive smoke: This may be caused by grease buildup. Clean the crumb tray and interior thoroughly. Ensure fatty foods are placed on a baking tray with a rack to allow fat to drip away.
- Digital display flickering: As noted in some demonstrations, the digital display may appear to flicker on camera due to refresh rates, but it operates normally in real life.
