5. Setup
- Unpacking: Carefully remove the OTG and all accessories from the packaging. Retain packaging for future transport or storage.
- Initial Cleaning: Wipe the exterior of the oven with a damp cloth. Wash all accessories (cooking tray, grill rack, rotisserie set, crumb tray) with warm, soapy water, rinse, and dry thoroughly.
- Placement: Place the OTG on a flat, stable, heat-resistant surface. Ensure there is at least 10-15 cm of clear space on all sides (back, top, and sides) for proper ventilation. Do not place near flammable materials or under cabinets.
- Power Connection: Ensure the power outlet matches the voltage specifications of the appliance (230V AC / 50Hz). Plug the power cord into a grounded electrical outlet. The cable length is approximately 1.5 meters.
- First Use (Burn-in): Before cooking food, operate the empty oven for approximately 15 minutes at the maximum temperature (230°C) using the 'Upper & Lower Heating' function. This helps to burn off any manufacturing residues and odors. A slight smoke or odor is normal during this process. Ensure the area is well-ventilated.

General Operation:
- Preheating: For best results, always preheat the oven to the desired temperature before placing food inside. Set the temperature knob, select the appropriate function, and set the timer for 10-15 minutes. The power indicator light will turn on.
- Placing Food: Once preheated, carefully place your food item on the grill rack or cooking tray using the provided handle or oven mitts. Close the oven door securely.
- Setting Time: Set the timer knob to the desired cooking duration. The power indicator light will remain on during operation. If using the 'Stay On' function, the oven will continue to operate until manually turned off.
- Monitoring: The illuminated chamber and tempered glass door allow you to monitor the cooking progress without opening the door.
- Completion: When the timer reaches 'Off', a bell will ring, and the heating elements will turn off. If using 'Stay On', manually turn the timer knob to 'Off'. Carefully remove the cooked food using appropriate heat protection.
Specific Functions:
- Baking/Roasting: Use 'Upper & Lower Heating' or 'Upper & Lower Heating + Fan' for cakes, pizzas, and roasts.
- Grilling/Toasting: Use 'Upper Heating' or 'Upper Heating + Fan' for grilling vegetables, paneer, or toasting bread.
- Rotisserie: For motorized rotisserie, select 'Upper Heating & Rotisserie' or 'Upper & Lower Heating + Rotisserie + Fan'. Secure the food onto the rotisserie rod, insert it into the oven's rotisserie sockets, and ensure it rotates freely.
7. Maintenance and Cleaning
Regular cleaning and maintenance will prolong the life of your OTG.
- Always Unplug: Before cleaning, always unplug the appliance and allow it to cool completely.
- Exterior: Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or metal scouring pads.
- Interior: Clean the interior walls with a damp cloth and mild detergent. For stubborn stains, use a non-abrasive cleaner. Avoid spraying cleaners directly onto the heating elements.

8. Troubleshooting
If you encounter any issues, refer to the following common problems and solutions:

- Uneven Cooking:
- Ensure the oven is preheated before placing food inside.
- Use the convection fan function for more even heat distribution.
- Avoid overcrowding the oven. Cook in smaller batches if necessary.
