Operating Instructions: Programming Your Remote
To program your new remote control, follow these steps carefully. This process involves setting the remote's code type and then pairing it with your garage door opener's receiver.
- 1. Enter Switching Code Mode: Press and hold the '2' and '3' buttons (left and right buttons) on your new remote control simultaneously for approximately 6 seconds. The indicator light on the remote will remain on, signaling that it has entered switching code mode. Release the buttons.
- 2. Select Code Type: While in switching code mode, press the button you wish to use for your garage door opener a specific number of times to select the desired code type:
- Press the button 1 time for Merlin 2.0 (433.3MHz, 433.92MHz, 434.54MHz).
- Press the button 2 times for 433.92MHz Liftmaster.
- Press the button 3 times for 433.92MHz Billion Code.
Choose the option that matches your existing Merlin remote or opener's specifications.
- 3. Exit Switching Code Mode: After selecting the code type, press any other button on the remote control to exit the switching code mode.
- 4. Pair with Receiver: Once the remote control is configured, you must now pair it with your garage door opener's receiver. Refer to your garage door opener's manual for specific instructions on how to put your receiver into learning mode. Typically, this involves pressing a 'Learn' or 'Code' button on the opener unit itself. Once the receiver is in learning mode, press the programmed button on your new remote control. The opener's light or a click will usually confirm successful pairing.

If you encounter difficulties, ensure your garage door opener is powered on and that you are within range of the receiver during the pairing process.

Consult the back of the remote for battery type (e.g., CR2032 coin cell) and replacement instructions.
- Cleaning: Clean the remote control with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the casing or internal components.
