6. Operating Instructions
6.1 Heating Food
- Prepare Food: Place your cooked food into the stainless steel inner container. You can also use the small salad container for side dishes, but it should not be placed in the main heating unit during heating.
- Secure Lid: Close the lid firmly and engage all four lid buckles to ensure a leak-proof seal. Ensure the steam vent is clear.
- Connect Power:
- For home or office use, connect the 110V power cable to the appropriate port on the lunch box, then plug it into a standard wall outlet.
- For car or truck use, connect the 12V/24V power cable to the appropriate port on the lunch box, then plug it into your vehicle's cigarette lighter socket.
- Start Heating: The power indicator light will illuminate, indicating that heating has begun. The lunch box uses PTC constant temperature heating to warm your food.
- Heating Time: Heating typically takes 20-30 minutes at an ambient temperature of 25°C (77°F). If food is refrigerated, heating time may be longer. The device will automatically maintain a temperature of approximately 60°C (140°F) once heated, preventing overheating and preserving food quality.
- Enjoy Meal: Once food is heated to your desired temperature, unplug the power cable before consuming.
