Frequently Asked Questions - CS125-AO Cosori

How do I set up my Cosori CS125-AO for the first time?

Remove all packaging, place the oven on a stable, heat-resistant surface. Wash all accessories and clean the interior. Run a test using the Toast function at Level 7 for about 10 minutes to burn off any residues. Then you can connect to the VeSync app for smart features.

What cooking functions are available?

The oven offers 11 functions: Toast, Bagel, Air Fry, Bake, Broil, Roast, Pizza, Cookies, Dehydrate, Ferment, and Warm. Each has pre-set time and temperature settings that can be customized.

How do I customize the default settings for a cooking function?

While the oven is not cooking or paused, select the desired function using the control knob. Adjust the time and temperature using the TIME/TEMP button and knob. Press and hold the control knob for 5 seconds until the oven beeps once to save as default. To reset, press and hold the knob without changes.

Can I control the oven remotely?

Yes, through the VeSync app you can monitor cooking progress and change settings remotely. However, for safety, you cannot start cooking remotely. The app also provides in-app recipes and allows customization.

What is the Shake Reminder and how do I use it?

The Shake Reminder alerts you halfway through cooking to shake or flip food for even cooking. Press the SHAKE button to enable it. When activated, the oven beeps and displays 'SHAKE'. Open the door, shake the basket, and close the door to resume.

How do I clean the oven and accessories?

Unplug and allow the oven to cool. Use a non-abrasive liquid cleanser or mild spray on a soft cloth to wipe surfaces. For glass, use glass cleaner. Accessories can be washed with warm soapy water; for stubborn grease, use a paste of baking soda and water. Always dry thoroughly before use.

What should I do if dark smoke comes out of the oven?

Immediately press START/PAUSE and unplug the oven. Wait for the smoke to clear before opening the door. Dark smoke indicates burning food. Do not use the oven until the issue is resolved. If it persists, contact Customer Support.

Does the oven have a preheat function?

Yes, functions Air Fry, Bake, Broil, Roast, Pizza, and Cookies have automatic preheat. When you start the function, the oven preheats and displays 'PrE'. You can cancel preheating by pressing START/PAUSE again to start cooking immediately.

How do I connect the oven to the VeSync app?

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.

General Safety

• When the oven is not in use, and before cleaning, press ⚙ to turn it off, then unplug from outlet. Allow to cool completely before putting on or taking off parts.
• Do not immerse the housing, cord, or plug in water or liquid.
• Closely supervise children near the oven.

• Do not use your oven if it is damaged, not working, or if the cord or plug is damaged. Contact Customer Support (see page 33).

• Do not use third-party replacement parts or accessories, as this may cause injuries.

• Do not use outdoors.
• Do not place the oven or any of its parts on a stove, near gas or electric burners, or inside another heated oven.
• Be extremely cautious when removing a tray or rack if it contains hot oil, grease, or other hot liquids.
• Do not clean with metal scouring pads. Metal fragments can break off the pad and touch electrical parts, creating a risk of electric shock.
• Clean the crumb tray after using. Accumulated grease and crumbs can overheat and catch fire.
• Do not store anything on top of your oven when in operation. Do not store anything inside your oven other than recommended accessories.
• Do not operate with a separate remote-control system.
• Only use as directed in this manual.
• Not for commercial use. Household use only.

While Cooking

• Do not place oversized foods or metal utensils (except for Cosori accessories) into your oven.
• Do not place paper, cardboard, or non-heat-resistant plastic into your oven, or any materials which may catch fire or melt.
• To avoid overheating, do not use metal foil in the oven unless directed. Use extreme caution when using foil, and always fit the foil as securely as possible. If the foil contacts the oven's heating elements, this can cause overheating and risk of fire.
• Never put baking or parchment paper into the oven without food on top. Air circulation can cause paper to move and touch heating elements.
• Always use heat-safe containers. Be extremely cautious if using containers that aren't metal or glass.
• Keep your oven away from flammable materials (curtains, tablecloths, walls, etc). Use on a flat, stable, heat-resistant surface away from heat sources or liquids.
• Immediately turn off and unplug your oven if you see dark smoke coming out. Food is burning. Wait for smoke to clear before opening the oven door.

Plug & Cord

• 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.

Note: This oven uses a short power-supply cord to reduce the risk of entangling or tripping. Use extension cords with care. The marked electrical rating of the extension cord must be as great as the rating of the oven (see page 3).

Electromagnetic Fields (EMF)

This oven complies with all standards regarding electromagnetic fields (EMF). If handled properly and according to the instructions in this user manual, the appliance is safe to use based on scientific evidence available today.

Shake Reminder

• The Shake Reminder is designed to remind you to check on your food, usually to shake it. Press SHAKE to turn on the Shake Reminder.
• You can use the Shake Reminder with any cooking function except Toast and Bagel. We especially recommend using the Shake Reminder with the Air Fry function (see page 17).
  • The Shake Reminder will appear halfway through cooking time.
  • If SHAKE is pressed during cooking, it will appear halfway through the remaining cooking time.
• The Shake Reminder will alert you with several beeps, and "("SHAKE") blink on the display.
  • The Shake Reminder will go away once you open the oven door to take out the basket.

What to Shake

• Small foods that are stacked, such as fries or nuggets, will usually need shaking.
• Without shaking, food may not be crispy or evenly cooked.
• You can flip other food, such as steak, to ensure even browning.

How to Shake

• Add the Shake Reminder to your cooking program by pressing SHAKE.
  • We recommend using the fry basket if you are shaking food. You can optionally use the rack or tray instead.
• When the Shake Reminder appears, take the fry basket out of the oven and shake, mix, or flip the food.
  • To shake food, hold the basket just above a heat-resistant surface for safety purposes. Then, shake the basket.
• If the basket is too heavy to shake, place the basket on a heat-resistant holder or surface. Then, shake the basket. Do not use this method if there is a risk of hot liquids splashing.
• If the basket is too heavy to shake and there are hot liquids present, place the basket on a heat-resistant holder or surface. Use tongs to mix or flip the food.
• When you open the oven door to take out the basket, the oven will pause cooking automatically. When you close the door, cooking will automatically resume.
• Avoid shaking longer than 30 seconds, as the oven may start to cool down.

Clean oven accessories (including trays, etc.) and oven interior after every use.

Note:

• The walls on the inside of the oven have a nonstick coating for easy cleaning.
• Do not use abrasive cleaners, metal scouring pads, or metal utensils on any part of the oven, including trays and other accessories. These will scratch or damage their surfaces.

• Let all surfaces dry completely before plugging in or turning on the oven.

Cleaning the Accessories

Note: After each use, slide out the crumb tray and discard crumbs.

1. Apply non-abrasive liquid cleanser or a mild spray solution to a soft, damp sponge or soft, plastic scouring pad (not the accessory surface). Wipe accessories and soak in warm, soapy water if necessary.

2. For stubborn grease:

a. In a small bowl, mix 2 US tbsp / 30 mL of baking soda with 1 US tbsp / 15 mL of water to form a spreadable paste.
