Configuración e programación

The LiftMaster 300MC remote operates on a 300 MHz frequency and uses 10 dip switches for coding. To program your new remote, you will need to match its dip switch settings to those of your existing remote or the receiver unit of your garage door opener/gate system.

Step 1: Locate Dip Switches

Abre o casing of your existing remote control or the receiver unit of your garage door opener/gate system to locate the 10 dip switches. These switches are typically small, numbered toggles.

Nota: The location of dip switches may vary. Refer to your original garage door opener or existing remote manual if you have difficulty locating them.

Step 2: Access Dip Switches on 300MC Remote

Abre con coidado a casing of your new LiftMaster 300MC remote. The dip switches are usually located inside the battery compartment or under a removable cover.

Step 3: Match Dip Switch Settings

Observe the ON/OFF (or +/0/-) positions of the 10 dip switches on your existing remote or receiver. Using a small tool (like a pen tip or small screwdriver), adjust the dip switches on your new LiftMaster 300MC remote to exactly match these positions.

Ensure each switch is set to the identical position (ON or OFF) as the original.
Incorrect settings will prevent the remote from operating your garage door or gate.

Paso 4: Proba de funcionamento

Once the dip switches are matched, close the casing of both remotes. Stand within range of your garage door opener or gate system and press the button on your new LiftMaster 300MC remote to test its functionality.

If the system does not respond, re-verify the dip switch settings and ensure the battery in the new remote is correctly installed and functional.
