2. Programación del control remoto
The RR3720 can be programmed to control most projector brands. It supports both direct code entry and an automatic search function.
Automatic Code Search (Recommended)
This method is generally the easiest and most effective for finding the correct code for your projector.
- Ensure your projector is turned on.
- Point the RR3720 remote towards your projector.
- Mantenga pulsado el "Auto" button on the remote until the indicator light (usually the Power LED) begins to flash. This indicates the remote is in search mode.
- Liberar el "Auto" button. The remote will now cycle through codes.
- As soon as your projector turns off or responds (e.g., displays a menu), immediately press any button (e.g., "Fuerza" or "Input") to lock in the code. If you wait too long, the remote may pass the correct code.
- Test all functions of the remote to ensure proper operation. If some functions do not work, repeat the automatic search process.
Direct Code Entry (Refer to included code list)
If you have a specific code for your projector brand, you can enter it directly.
- Locate the code list provided with your RR3720 remote. Find the codes for your projector brand.
- Mantenga pulsado el "Fuerza" botón y el "Input" button simultaneously until the indicator light stays lit.
- Enter the 3-digit code for your projector brand using the number buttons (1-4, or other buttons if they have secondary number functions).
- If the code is accepted, the indicator light will turn off. If it flashes rapidly, the code was incorrect or not recognized.
- Test the remote's functions. If it does not work, try another code from the list for your brand or use the automatic search method.

Reemplazo de batería
Replace batteries when the remote's indicator light does not illuminate or flashes weakly, or when the remote becomes unresponsive. Always replace both batteries at the same time with new AAA alkaline batteries.
Limpieza
To clean the remote, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the remote's surface or internal components.
Almacenamiento
Store the remote in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period (e.g., more than one month), remove the batteries to prevent leakage and potential damage to the remote.
Solución de problemas
- El control remoto no responde:
- Compruebe si las pilas están insertadas correctamente con la polaridad correcta.
- Reemplace las baterías viejas con baterías AAA nuevas.
- Asegúrese de que no haya obstrucciones entre el control remoto y el receptor de infrarrojos del proyector.
- Verify that the remote is programmed correctly for your projector model. Re-attempt the automatic code search.
- Algunas funciones no funcionan:
- The current code may not fully support all functions of your specific projector model. Try repeating the automatic code search to find a more compatible code.
- Some projectors may not have certain functions (e.g., volume control if no internal speakers).
- Projector does not turn off during auto search:
- Ensure the remote is pointed directly at the projector's IR receiver.
- Make sure the projector is powered on before starting the auto search.
