- Connect the included USB Type-C cable to the fan.
- Connect the other end of the USB cable to a compatible USB power source (e.g., computer USB port, USB wall adapter, power bank).

Operating Instructions
1. Power On/Off and Speed Adjustment
The fan is controlled via a single main button (touch control).
- To Power On: Press the main button once. The fan will start at the Low speed setting.
- To Adjust Speed: Press the main button repeatedly to cycle through the speed settings:
- 1st Press: Low
- 2nd Press: Mid
- 3rd Press: High
- 4th Press: Turbo
- 5th Press: Power Off
- To Power Off: Continue pressing the button until the fan turns off, or press and hold the button for a few seconds (common behavior for single-button controls, not explicitly stated but logical).
2. Dual Blade Technology Explained
The Rhythm Air fan utilizes a unique dual blade system for superior airflow. The rear blades pull air into the fan, while the front blades direct this air into a focused, strong column. This differs from regular handheld fans with a single blade, which often result in unfocused airflow.

3. Using the Adjustable Stand
The fan features a 4-step adjustable stand integrated into its handle, allowing you to position it on a flat surface for hands-free operation.
- Gently pull out the stand from the back of the handle.
- Adjust the stand to one of the four available angles to achieve your desired airflow direction.
- The fan can also be held comfortably in hand for portable use.

Maintenance
1. Cleaning
To ensure optimal performance and longevity of your fan, regular cleaning is recommended.
- Ensure the fan is powered off and disconnected from any power source before cleaning.
- Wipe the exterior of the fan with a soft, dry cloth.
- For stubborn dirt, a slightly damp cloth can be used, but ensure no water enters the fan's internal components.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the fan's finish or internal parts.
- The manufacturer recommends "Hand wash" for care instructions, which implies gentle cleaning of the exterior.
2. Storage
When not in use for extended periods, store the fan in a cool, dry place away from direct sunlight and extreme temperatures.
