2. Point the remote directly at the infrared sensor on the Sony device.
3. Maintain a clear line of sight; avoid obstacles between remote and device.
4. For advanced functions (like BRAVIA Sync), additional setup via the TV menu may be required.

Tip: If the remote partially works (e.g., volume but no power), try reprogramming with an alternate Sony code.

Learning Function (Custom Codes)

For models equipped with a learning function, you can teach the RMT-144A commands from another remote.

1. Place the two remotes facing each other, 2-3 cm apart.
2. On the RMT-144A, press and hold the LEARN button and the button you wish to program (e.g., POWER) until the indicator flashes.
3. On the original remote, press and hold the corresponding button you want to copy. The indicator on the RMT-144A will flash rapidly, then stay on to confirm learning.
4. Test the learned button. Repeat for other functions as needed.

WARNING! Learning may not work with all remotes (e.g., RF remotes). Ensure the original remote is IR. Do not expose the IR sensors to bright sunlight during the process.
