Operating Instructions
Scheduled Heating Mode
This mode allows you to set a specific mealtime, and the lunch box will automatically begin heating in advance to ensure your food is hot and ready at the desired time. The memory function saves your settings for daily auto-start.
- Set Current Time: First, set the current time on the device to match the actual time.
- Schedule Mealtime: Then, set your desired mealtime (e.g., 12:00 PM). The device will calculate when to start heating.
- Power On: Ensure the lunch box is powered on at least 2 hours before the scheduled mealtime for automatic heating to function correctly.

Instant Heating Mode
For immediate heating, use the Instant Heating Mode. This mode bypasses scheduled settings and initiates a full 2-hour heating cycle immediately. This is suitable for unplanned meals or sudden schedule changes. For routine use, scheduled heating is recommended.

Temperature Adjustment
The heating plate can reach temperatures between 170°F (77°C) and 220°F (104°C). Use the up/down arrows on the control panel to adjust the desired heating plate temperature.

Heating Tips
- The display shows the temperature of the heating plate. The actual food temperature will be slightly lower to prevent burns and preserve flavor.
- For optimal heating and heat retention, place the lunch box in the insulated bag during the heating process.
- Ensure food contains moisture. The lunch box utilizes moisture to generate steam for thorough heating. It works best with foods like pasta, meats, vegetables, stews, and saucy dishes. If food is dry, add a small amount of water to the container to enhance heating.
- Ensure food makes contact with the bottom of the container for effective heating, as heat is applied from the base. For irregularly shaped items, add sauce or water to boost steam.
- For more thorough heating, consider increasing the temperature setting or setting your mealtime 20-30 minutes earlier to allow for extended warming.
- For frozen food, it is highly recommended to thaw it in the refrigerator overnight before heating.
