5. Setup

1. Prepare the Bottle: Fill your baby bottle with milk or desired liquid.
2. Wrap the Warmer: Place the bottle inside the YARNOW warmer wrap. The flexible PU material allows it to stretch and conform to most standard baby bottle sizes. Secure the wrap around the bottle using the integrated fasteners (e.g., hook-and-loop closure).
3. Connect Power: Connect the USB cable from the warmer's control unit to a compatible USB power source. This can be a power bank, car charger, laptop, or a wall adapter (not included).

6. Operating Instructions

1. Power On: Once connected to a power source, press the power button on the control unit to activate the heating function. An indicator light (if present) will illuminate to show the device is active.
2. Heating Process: The warmer will begin to heat the liquid. The heating time may vary depending on the initial temperature of the liquid, the volume, and the ambient temperature. The device is designed for fast and even heating.
3. Temperature Control: The warmer maintains a consistent warm temperature. There are no manual temperature adjustments on this model; it is designed to warm to a safe and comfortable feeding temperature.
4. Check Temperature: Before feeding, always test the liquid temperature by dripping a small amount onto your wrist to ensure it is not too hot.
5. Power Off: Press the power button again to turn off the heating function. Disconnect the USB cable from the power source when warming is complete or when the device is not in use.
