4.4 External RF Module Installation

The V16 transmitter includes a dedicated bay for external high-frequency modules. This interface is directly compatible with JR, Blacksheep, and other equivalent brands. Carefully insert your chosen external RF module into the bay, ensuring a secure connection.

4.5 Initial Power On

After installing batteries and any external modules, press and hold the power button to turn on the transmitter. The 4.3-inch color touch screen will display the boot sequence. Follow any on-screen prompts for initial setup or calibration.

5. Operation

5.1 Touch Screen Interface

The V16 features a large 4.3-inch color touch screen for easy and clear operation. Navigate menus, adjust settings, and monitor telemetry data directly on the screen. The new touch panel upgrade is equipped for multiple scenarios.

5.2 Gimbal and Switch Controls

Utilize the CNC Hall Metal Rockers for precise control of your model. The transmitter is equipped with 6-mode switches (S1-SD, LS, RS, T1-T6) that can be defined at will. Users can program these switches to customize their functions and corresponding LED colors. Multi-Color LEDs are used, allowing you to create your own preferred visual feedback.

5.3 Motion Control (V16 MAX/PRO)

The V16 MAX and V16 PRO models are equipped with a 6-axis gyroscope, 3-axis accelerometer, and 3-axis gyroscope for immersive motion control. This high-precision motion sensing control, supported by EdgeTX, provides a realistic flight experience with voice assistant switching.

5.4 Intelligent Voice Assistant (V16 MAX/PRO)

The V16 MAX and V16 PRO models feature an intelligent voice interaction control circuit, enabling true human-machine interaction. Users can customize their voice and create their own style of voice control functions for an enhanced operational experience.

5.5 Head-tracking Function

The V16 transmitter supports a head-tracking function, allowing you to switch to aircraft head pursuit mode. In this mode, the perspective of the aircraft is controlled by somatosensory input, providing a more immersive experience.

6. Maintenance

6.1 Cleaning

Regularly clean the exterior of your transmitter with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials that could damage the screen or casing.

6.2 Battery Care

The V16 features a charging circuit that automatically stops charging when overvoltage is detected in the battery cells, protecting the battery from damage. Always use appropriate batteries and chargers. Store the transmitter in a cool, dry place when not in use, and avoid leaving batteries fully discharged or fully charged for extended periods.

6.3 Firmware Updates

The SWD debugging port of the MCU is conveniently located at the bottom of the radio, making it easier for upgrading and debugging firmware. Regularly check the HelloRadio website or community forums for the latest firmware updates to ensure optimal performance and access to new features.

7. Troubleshooting

7.1 Abnormal Voltage or Current Alarms

The V16 is equipped with three voltage and current measurement units with an accuracy of +/-0.1%. These units independently measure the voltage of single battery cells, monitor charging voltage and current in real-time, and measure the working voltage and current of the overall system and internal/external RF modules. If abnormal voltage or current is detected, the system will issue an alarm or shut down to protect the radio and modules. If an alarm occurs, immediately power off the transmitter, check battery connections, and ensure no short circuits or component damage. Consult the quick start guide or online resources for specific alarm codes.

7.2 General Issues

• Transmitter not powering on: Check battery installation and charge level. Ensure batteries are correctly inserted and fully charged.
• No response from model: Verify binding procedure between transmitter and receiver. Check RF module status and antenna connections.
• Screen not responding: Perform a soft reset (refer to quick start guide for specific button combinations). If issue persists, check for firmware corruption.

9. User Tips

• Regular Calibration: Periodically calibrate your gimbals and switches through the transmitter's menu to ensure maximum precision.
• Model Memory Management: Utilize the SD card to back up your model settings and configurations. This is crucial before performing firmware updates.
• Range Testing: Always perform a range test before flying a new model or after any significant changes to your setup to ensure reliable communication.
• Environmental Awareness: Avoid operating your transmitter in extreme temperatures or high humidity to prolong its lifespan.
• Practice with Simulator: If new to RC flying, practice extensively with a flight simulator connected via the TRS3.5mm trainer port to familiarize yourself with controls without risking your model.
