3. Operating Instructions
3.1 Smart Reservation Mode
This mode allows you to set a target meal time. The lunch box will automatically calculate and begin heating approximately 2 hours in advance to ensure your food is warm when needed. Ensure the lunch box is turned on at least 2 hours before your set meal time for the preheating cycle to initiate.

3.4 Heating Tips for Optimal Results
- Temperature Display: The screen shows the heating plate's temperature. The food's core temperature will be slightly lower, designed to prevent overheating and preserve taste.
- Boost Efficiency: Use the included insulation bag to improve heating speed and heat retention.
- Even Heating: For drier foods, add a small amount of water to create steam. Ensure food is in contact with the bottom of the container. For large items, adding a small amount of sauce or water can promote thermal circulation.
- Thorough Heating: If more thorough heating is desired, moderately increase the temperature or set the reservation time 20-30 minutes earlier.
- Frozen Foods: For best results, thaw frozen food in the refrigerator overnight before heating.
