4.4. Universal Infrared (IR) Remote Function
This remote includes five programmable infrared learning keys, allowing it to learn functions from your existing TV remote. This enables control of common TV functions directly from the Air Mouse remote.
IR Learning Steps:

- Press and hold the designated IR learning key on the Air Mouse remote (refer to the remote's button layout for specific keys, usually marked for IR learning). The LED indicator will typically blink slowly.
- While holding the learning key, press the button on your original TV remote that you wish to copy. The LED on the Air Mouse remote should blink rapidly, indicating successful learning.
- Repeat for other programmable keys.
- Press the learning key again to exit IR learning mode.
4.5. LED Indicators
