Check:
You understand the correct setup, operation, and safety precautions for your lunch box.
Step 3: Prepare your meal and place it inside the container
Fill your food container with the meal you want to heat, leaving some space for expansion if necessary. Place the container inside the lunch box.
Tip:
Use microwave-safe or heat-resistant containers. Avoid overfilling to prevent spills or uneven heating.
Check:
The meal is properly contained and positioned inside the lunch box, ready for heating.
Step 4: Plug in the lunch box and turn it on
Connect the power cord to the lunch box and plug it into a compatible outlet. Switch the device on according to the manual’s instructions.

Ensure the cord is not strained or placed where it could be a tripping hazard.
Check:
The lunch box’s indicator light (if available) turns on, confirming it is heating.
Step 5: Set the heating time or temperature
Adjust the timer or temperature control as specified in the manual for your meal type. If unsure, start with a short period (10-15 minutes) and add more time if needed.

Use the default or recommended settings for your food to avoid overheating or underheating.
Check:
The device is operating normally, and the meal begins to heat evenly.
Step 6: Allow the meal to heat and monitor progress
Let the lunch box run for the set time. Avoid opening it during heating to prevent heat loss and uneven warming.
Tip:
If your lunch box has a transparent lid or window, observe the meal to check progress without opening it.
Check:
The meal has reached your desired temperature, indicated by time elapsed or a built-in indicator.
Step 7: Unplug and carefully remove your meal
Turn off the device and unplug it. Using heat-resistant gloves or a cloth, carefully remove the container from the lunch box.
