1. Introducció
The SMG-239 is a versatile multi-frequency remote control designed to clone existing fixed and rolling code remotes for various access control systems, including garage doors, gate doors, barriers, and sliding gates. Its 4-in-1 functionality allows it to control up to four different devices or brands simultaneously, operating across a wide frequency range from 280MHz to 868MHz.

5. Setup and Programming (Cloning)
The SMG-239 remote control requires face-to-face cloning from your original remote. The process differs slightly for fixed code and rolling code remotes.
5.1. Cloning Procedure
- Esborra el codi existent: Press and hold the two top buttons (Button 1 and Button 2) on the SMG-239 simultaneously until the LED flashes rapidly (approximately 3 seconds). Release the buttons. This clears any pre-existing codes.
- Comandaments a distància de posició: Place your original remote control and the SMG-239 side-by-side, as close as possible.
- Iniciar la clonació: Press and hold a button on your original remote that you wish to clone. Simultaneously, press and hold the corresponding button on the SMG-239 where you want to store the code.
- Observe LED: The LED on the SMG-239 will first flash slowly, then rapidly, indicating successful cloning.
- Repetiu per a altres botons: Repeat steps 3 and 4 for any other buttons you wish to clone.

5.2. Fixed Code vs. Rolling Code
- Fixed Code Remotes: After successfully cloning a fixed code remote, the SMG-239 will be ready for immediate use.
- Rolling Code Remotes: For rolling code remotes, after cloning, the SMG-239 will need to be programmed or activated directly on your receiver unit (e.g., garage door opener motor, gate control board). Refer to your receiver's manual for specific instructions on how to pair a new remote.
Detailed instructions will be provided in the English manual included in your package.

6. Funcionament
Once successfully programmed, the SMG-239 operates identically to your original remote. Each of the four buttons can be assigned to control a different device or function:
- Botó 1: Typically used for Garage Door operation.
- Botó 2: Typically used for Gate Door operation.
- Botó 3: Typically used for Barrier control.
- Botó 4: Typically used for Sliding Gate operation.
Press the assigned button to activate the corresponding device.

7. Manteniment
7.1. Substitució de la bateria
The SMG-239 uses a CR2032 3V battery. When the remote's range decreases or the LED indicator becomes dim, it's time to replace the battery.
- Localitzeu el compartiment de la bateria a la part posterior del comandament a distància.
- Carefully open the compartment using a small tool or your fingernail.
- Traieu la bateria CR2032 antiga.
- Inseriu una nova bateria CR2032 amb el costat positiu (+) cap amunt.
- Tanqueu el compartiment de la bateria de manera segura.

7.2. Neteja
Wipe the remote control with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
8. Consells d'usuari
- For optimal cloning results, ensure both the original remote and the SMG-239 have fresh batteries.
- When cloning, try different positions if the first attempt is unsuccessful (e.g., back-to-back, antenna-to-antenna).
- If you encounter issues with rolling code remotes, remember that an additional pairing step with your receiver is almost always required after cloning.
- Keep the remote control away from extreme temperatures and moisture.
9. Solució De Problemes
- Remote not cloning: Ensure the SMG-239's code is cleared before attempting to clone. Make sure the original remote is transmitting a strong signal and is held very close to the SMG-239. Try replacing batteries in both remotes.
- Cloned but not working (Rolling Code): Remember to program/activate the SMG-239 with your receiver unit after cloning. This is a common step for rolling code systems.
- Interval de funcionament curt: Check the battery level of the SMG-239. Obstructions between the remote and the receiver can also reduce range.
