2. Safety Warnings

• The user must possess relevant professional knowledge for mounting and operating VTX products. Any illegal use may cause potential danger.
• Operate FPV equipment under professional guidance and read this manual carefully. The user assumes responsibility for personal injury or property damage resulting from ignoring these statements or violating operating regulations.
• VTX units generate significant heat during normal operation. Ensure adequate airflow for a well-ventilated environment to prevent burns. Avoid touching the VTX during operation.
• Ensure all cables and plugs are correctly installed. Before powering up, verify the antenna is correctly installed to the VTX RF output.
• The VTX contains precision components. Do not disassemble, repair, or modify this product personally. Contact your dealer for technical support if the VTX malfunctions.
• Adhere to local radio regulations. A HAM license may be required for operating on HAM channels or at certain power levels. Some channels may require notification to local radio regulatory agencies.
• Ensure compliance with all local laws and regulations regarding drones and radio operation. Strictly avoid flying in no-fly zones such as airports, military facilities, and over crowds.
• For TANK SOLO: The 5V output is exclusively for a camera or cooling fan. Do not connect power input/battery to the 5V output, as this will cause serious damage to the VTX.

6. Operating Instructions

6.1 Power and Frequency Settings

The VTX features a button for controlling power levels and channels. The chosen channel and band will be indicated by flashes of the LED. The number of flashes corresponds to the band (e.g., 1 flash for Band A, 2 for Band B, etc.) and the channel within that band.

Frequency Table (Example for MAX SOLO, refer to image for full table)

Power Level Settings

• PIT Mode: Indicated by a flashing Power LED. In this mode, the VTX transmits at a very low power to prevent interference during setup.
• Exiting PIT Mode: Press and HOLD the Power Button to cycle through available power levels.
• Overheated: If the VTX overheats, the Power LED will flash rapidly, and the VTX will temporarily reduce transmit power. Transmission will resume normally once the unit cools down.

6.2 SmartAudio Control

Both RUSH MAX SOLO and RUSH TANK SOLO VTX units feature built-in SmartAudio Control Protocol, allowing quick parameter adjustments via OSD (On-Screen Display) or radio control when connected to a Flight Controller (FC) or CRSF receiver.

1. Connect the SmartAudio port on the VTX to a Free UART-TX pad on your Flight Controller.
2. In the BetaFlight configurator, navigate to the 'Ports' tab. For the UART connected to the VTX's RX pad, select 'TBS SmartAudio' under the 'Peripherals' column. Set the speed to <auto> and save the settings.
3. To access the OSD menu via your radio control: Center the throttle (THR), move the yaw stick to the left, and the pitch stick up simultaneously.
4. Within the OSD menu, navigate to 'Function' > 'VTX SA' to set the VTX working state.
5. In the 'CONFIG' menu: If set to 'RACE' mode, the VTX will automatically enter PIT mode after booting. If set to 'FREE' mode, the VTX will transmit normally after booting. After changing the working mode, you must reconnect power for the settings to take effect.

7. Maintenance

• Keep the VTX clean and free from dust and debris.
• Ensure adequate airflow around the VTX during operation to prevent overheating, especially for high power settings.
• Regularly check all wiring connections for looseness or damage.
• Inspect the antenna for any bends or breaks. Replace if damaged to ensure optimal performance and prevent VTX damage.
• Store the VTX in a dry, cool environment when not in use.

8. Troubleshooting

• No Video Signal:
  • Check all video connections between the camera, VTX, and flight controller.
  • Ensure the antenna is securely connected to the VTX.
  • Verify the VTX is powered on and receiving adequate voltage.
  • Confirm your FPV goggles/receiver are on the correct frequency and band.
• Poor Video Quality / Static:
  • Check for interference from other electronic components on the drone.
  • Ensure the VTX has sufficient airflow to prevent overheating, which can degrade signal quality.
  • Verify antenna condition and orientation.
  • Try a different channel or power level.
• VTX Overheating:
  • Ensure the VTX is mounted in a location with good airflow.
  • Consider adding a small cooling fan if space permits (especially for MAX SOLO).
  • Reduce the power output if high power is not strictly necessary for your flight range.
• SmartAudio Not Working:
  • Verify the SmartAudio wire is correctly connected to a UART-TX pad on the flight controller.
  • Check BetaFlight 'Ports' tab settings to ensure TBS SmartAudio is enabled on the correct UART.
  • Ensure the flight controller firmware supports SmartAudio.
