3. Operating Instructions
The Air Relax Plus AR-3 control unit features an intuitive interface with dedicated buttons for power, mode selection, target area selection, pressure adjustment, and time setting.
Control Unit Functions:
- ON/OFF Button: Powers the device on or off.
- MODE Button: Cycles through the available therapy modes (P, S, F).
- TARGET Button: Allows selection of specific chambers for targeted compression.
- PRESSURE Button: Adjusts the compression intensity (4 levels).
- TIME Button: Sets the session duration (15 or 30 minutes).
Therapy Modes:
The AR-3 offers three primary therapy modes and a targeted compression option:
- P Mode (Progressive Peristaltic Therapy): Chambers inflate sequentially from the feet upwards. Once the third chamber inflates, the first chamber deflates. This continues until all chambers are inflated, then they deflate in sequence.
- S Mode (Cyclical Uniform Therapy): Each chamber inflates one at a time, holding the pressure until all chambers are full. Then, all chambers deflate simultaneously.
- F Mode (Continuous Therapy): All chambers inflate simultaneously and hold pressure for the duration of the session, then deflate together.
- Targeted Compression Mode: Use the TARGET button to select specific chambers you wish to inflate. This allows for focused compression on particular areas.
To begin a session, power on the device, select your desired mode, adjust pressure and time, and then start the massage. After use, turn off the device and disconnect the leg sleeves.

4. Sizing Information
To ensure optimal performance and comfort, select the correct leg sleeve size. Measure the length from the top of your inside leg at the crotch to the heel (inseam). If you are between sizes, it is recommended to choose the longer sleeves for a more accurate result.
