• 단추: Used for binding and other functions
• LED : Green, Blue, Red indicators for status
• 2.4G 안테나: Two IPEX1 connectors for 2.4GHz antennas
• 900M 안테나: One connector for 900MHz antenna

4.2 Antenna Installation and Orientation

Proper antenna placement is critical for optimal signal reception and range. Ensure antennas are mounted away from conductive materials and at appropriate angles.

• Mount the 2.4GHz antennas at a 90-degree angle to each other for diversity.
• Position the 900MHz antenna to provide the best possible omnidirectional coverage, ideally perpendicular to the 2.4GHz antennas if space allows.
• Ensure the active part of the antenna (the last 31mm for 2.4GHz, and the full length for 900MHz) is clear of carbon fiber, metal, or other signal-blocking materials.

4.3 바인딩 절차

To establish communication between your FrSky Tandem series transmitter and the TD MX receiver, follow these binding steps:

1. Power on your transmitter and navigate to the RF System menu.
2. Select the TD protocol and choose the 'Bind' option.
3. Press and hold the F/S (Fail-Safe) button on the TD MX receiver while powering it on.
4. Release the F/S button. The Red and Green LEDs on the receiver will flash, indicating it is in binding mode.
5. On your transmitter, select 'Bind' again. The receiver's LEDs will change to indicate successful binding (refer to LED Status Indicators section).
6. Power cycle both the receiver and transmitter. The receiver should now show a solid Green LED, indicating normal operation.

5. 사용 설명서

5.1 개의 LED 상태 표시기

The TD MX receiver uses a combination of Green, Blue, and Red LEDs to indicate its current status. Understanding these indicators is crucial for proper operation and troubleshooting.

5.2 범위 확인

Before each flight, especially with a new setup or after modifications, perform a range check to ensure adequate signal strength. This procedure helps verify the integrity of your radio link.

1. Place your model at least 1 meter (3 feet) off the ground.
2. On your transmitter, activate the 'Range Check' mode (usually found in the RF System menu). This typically reduces the transmitter's power output.
3. Walk away from the model while observing the receiver's LED status and control response.
4. Ensure reliable control and telemetry feedback at a distance of at least 30 meters (100 feet).
5. Exit Range Check mode on your transmitter before flying.

5.3 OTA 펌웨어 업데이트

The TD MX receiver supports Over-The-Air (OTA) firmware updates directly from your compatible FrSky transmitter. This allows for convenient updates without physical connection to a computer.

• Ensure your transmitter has the latest firmware and the desired receiver firmware file loaded onto its SD card.
• Follow the specific OTA update procedure outlined in your transmitter's manual.
• During the update process, keep the transmitter and receiver close to each other and avoid interruptions.

5.4 Black Box Function

The Black Box function records flight data, which can be invaluable for analyzing flight performance or diagnosing issues. This data can typically be accessed and reviewed via your transmitter or companion software.
