Important Usage Notes 1. Memory Function Application: The memory function acts like a built-in clock. Simply set the time once initially, and it will automatically synchronize to the current moment every time you use it afterwards. This is especially convenient for people with regular meal schedules.2. Heating Temperature Specification: The lunch box offers an adjustable heating range of 170°F to 220°F. Please note that this temperature refers to the heating plate itself, not the final temperature of the food contents. 3. Heating Time Planning: A full heating cycle requires approximately 2 hours. To ensure your meal is thoroughly warmed, please plan ahead and start the heating process at least 2 hours before your intended meal time. 4. Battery Level Pre-check: Before each use, please verify the battery level. For a complete 2-hour heating cycle, it is recommended to ensure the battery is charged to at least 90% to prevent interruption. 5. Material Safety Notice: The inner pot is constructed from food-grade 304 stainless steel, which contains nickel. Individuals with a known nickel allergy are advised against using this product. 6. Optimal Heating Tip: As heating originates from the bottom, ensure full contact between the food and the container base for efficient heat transfer. For more even heating, consider adding a small amount of water to drier foods. 7. Compatibility Advisory: To ensure optimal performance and safety, please use the provided original charger and inner pot. The use of non-original components may lead to compatibility issues or suboptimal performance.
