3. Setup and Programming
The BFT D111171 VTM2 transmitter requires programming to a compatible BFT receiver unit before use. The specific programming procedure varies depending on the receiver model.
General Programming Steps (Consult Receiver Manual):
- Ensure the receiver unit is powered on.
- Locate the programming button or sequence on your BFT receiver. This is often labeled 'PROG', 'MEMO', or similar.
- Activate the receiver's programming mode (e.g., press and hold the programming button until an LED changes state).
- While the receiver is in programming mode, press the desired button on your new BFT D111171 transmitter.
- The receiver's LED or indicator should confirm successful programming.
- Exit the receiver's programming mode (e.g., short press the programming button or wait for timeout).
For detailed instructions, refer to the user manual of your specific BFT gate or garage door opener receiver unit, or visit the official BFT website for support documentation.
4. Operating Instructions
Once programmed, operating the BFT D111171 VTM2 transmitter is straightforward:
- Button 1 (Top Green Button): Typically controls Channel 1. Press this button to activate the associated function (e.g., open/close gate).
- Button 2 (Bottom Green Button): Typically controls Channel 2. Press this button to activate the associated function (e.g., pedestrian opening, light control).
Ensure you are within the operational range of your receiver unit for reliable communication.
5. Maintenance
Battery Replacement:
The transmitter requires a battery for operation (battery not included with purchase). When the transmission range decreases significantly or the indicator light (if present) does not illuminate, it is likely time to replace the battery.
- Carefully open the transmitter casing (refer to specific model instructions if available, often involves a small screw or clip).
- Remove the old battery.
- Insert a new battery of the correct type and polarity. (Battery type is typically a 12V A23 or similar, but verify with the old battery or BFT specifications).
- Close the casing securely.
Cleaning:
Clean the transmitter with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or internal components.
6. Troubleshooting
- Transmitter not working:
- Check if the battery is inserted correctly and has sufficient charge. Replace if necessary.
- Ensure the transmitter is properly programmed to the receiver. Re-program if unsure.
- Verify that the receiver unit is powered on and functioning correctly.
- Reduced operating range:
- The battery may be low. Replace it.
- Check for sources of interference (e.g., other radio devices, large metal objects) between the transmitter and receiver.
- Ensure the receiver's antenna (if external) is not obstructed or damaged.
- Buttons unresponsive:
- Check for physical damage to the buttons or casing.
- Ensure the battery is correctly installed.
If problems persist after attempting these troubleshooting steps, contact BFT customer support or a qualified technician.
