5. Setup Instructions
- Prepare the Wraps: Lay the leg compression wraps flat. Ensure the left (L) and right (R) wraps are correctly identified.
- Wear the Wraps: Insert your feet into the foot part of the wraps, then wrap the calf sections around your legs. Secure the Velcro straps firmly but comfortably. Do not overtighten, as the air chambers will inflate.
- Attach Size Extenders (Optional): If your calves require more room, attach the included size extenders to the Velcro fasteners on the wraps before securing them.
- Connect Air Hoses: Ensure both air hoses from the wraps are securely inserted into the corresponding ports on the handheld controller. The controller has clearly marked 'L' and 'R' ports.
- Connect Power: Plug the power adapter into the handheld controller, then plug the adapter into a power outlet.

7. Modes and Intensities
The FT-009A offers a versatile massage experience with its distinct modes and adjustable intensities:
- Mode A (Sequence Mode): This mode simulates kneading and stroking of tissues, with air chambers inflating and deflating in a progressive sequence from the feet upwards. This helps to gently push blood flow towards the heart, aiding in muscle recovery and reducing fatigue.
- Mode B (Whole Mode / Circulation): This mode focuses on broader compression, often inflating multiple chambers simultaneously or in a pattern designed to enhance overall blood circulation throughout the treated area. It is particularly beneficial for addressing leg edema and general swelling.
Each mode can be customized with 3 Intensity Levels (Low, Medium, High), allowing you to find the perfect pressure for your comfort and therapeutic needs. The device incorporates 10 professional massage techniques across these modes to provide a comprehensive and effective massage.

- Storage: Store the massager in a cool, dry place away from direct sunlight and extreme temperatures. Keep it away from sharp objects to prevent damage to the air bags.
