Setup

1. Battery Installation

The DDF-350 transmitter can be powered by either AA batteries or the included 2-cell LiPo battery pack.

• AA Batteries: Insert the required number of AA batteries into the battery compartment, ensuring correct polarity.
• LiPo Battery Pack: To use the included LiPo battery, carefully remove the AA battery tray. This tray is secured by small tabs around its edges; use a small flat-bladed screwdriver to gently release them. Once the tray is removed, disconnect the connector from the bottom of the transmitter (if present) and then connect the LiPo battery pack, paying close attention to the polarity markings inside the compartment.

Note: The transmitter does not have built-in charging circuitry for the LiPo battery. An external LiPo charger is required to charge the battery pack.

2. Binding the Receiver

To establish communication between the transmitter and receiver, a binding process is required.

1. Ensure both the transmitter and receiver are powered off.
2. Connect a bind plug (not included, typically comes with the receiver or ESC) to the BIND/VCC port on the P10F(G) receiver.
3. Apply power to the receiver (e.g., via an ESC or separate battery). The receiver's LED should flash rapidly, indicating it's in binding mode.
4. While holding down the BIND button on the DDF-350 transmitter (refer to the transmitter diagram for exact location), power on the transmitter.
5. Release the BIND button on the transmitter once its screen indicates binding is in progress or successful.
6. The receiver's LED should turn solid, indicating a successful bind.
7. Power off both the receiver and transmitter. Remove the bind plug from the receiver.
8. Power on the transmitter first, then the receiver. Verify that the controls respond correctly.

3. Initial Configuration

After binding, it is recommended to perform initial configuration steps:

• Channel Assignment: Ensure your servos and ESC are connected to the correct channels on the receiver.
• Servo Reversing: Adjust servo direction as needed through the transmitter's menu to ensure correct steering and throttle response.
• End Point Adjustment (EPA)/Travel: Set the maximum travel for each channel to prevent over-stressing servos or mechanical components.
• Trim Adjustments: Fine-tune neutral positions for steering and throttle.

Operating Instructions

1. Basic Controls

The DDF-350 transmitter features standard pistol-grip controls:

• Steering Wheel: Controls the steering of your vehicle (Channel 1).
• Throttle Trigger: Controls forward/reverse and braking (Channel 2). Pull for forward, push for reverse/brake.
• Auxiliary Channels (CH3-CH10): These channels can be assigned to various functions such as lights, winches, gear shifts, or other accessories, depending on your vehicle's setup.

2. Digital Screen and Menu Navigation

The DDF-350 features a TFT-LCD (IPS) screen for accessing settings and monitoring telemetry. Navigation is typically done using the dial and buttons located near the screen.

• Main Display: Shows real-time information such as transmitter battery voltage, receiver voltage (if telemetry cable is used), RSSI (Received Signal Strength Indicator), channel output percentages, and a timer.
• Menu Access: Use the navigation dial and buttons to enter the main menu.
• Parameter Adjustment: Rotate the dial to scroll through options and press to select. Adjust parameters like servo reverse, EPA, sub-trim, dual rates, and exponential.
• Model Selection: The transmitter supports 10 groups of model selection, allowing you to save settings for different vehicles.

3. Advanced Functions

• Tank Mixing Control: Configure mixing for tank-style steering (e.g., controlling two motors independently for track vehicles).
• Program Custom Mixing: Create custom mixes between channels for complex control setups.
• PPM Output and Input: Supports PPM for compatibility with various flight controllers or simulators.
• Head Tracking Function: For FPV applications, allows head movements to control camera pan/tilt.
• Wireless Training: Enables connection to another compatible transmitter for training purposes.

Firmware Upgrade

The DDF-350 transmitter supports firmware upgrades via USB. This allows for improvements, bug fixes, and new features to be added.

1. Connect the remote control to a computer using a USB cable. It should be recognized as a USB flash drive.
2. Download the latest firmware file from the manufacturer's official website.
3. Drag and drop the firmware file into the root directory of the USB flash drive (the transmitter's internal storage).
4. Safely eject the USB device from your computer.
5. Disconnect the USB cable. The transmitter will automatically initiate the upgrade process. Do not power off the transmitter during this time.
6. Once the upgrade is complete, the transmitter will restart.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the transmitter and receiver. Avoid using solvents or harsh chemicals.
• Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
• Battery Care: If using a LiPo battery, follow proper charging and storage guidelines to prolong its lifespan and ensure safety.
• Inspection: Periodically check all connections and cables for wear or damage.

Troubleshooting

• No Power:
  • Check battery installation and charge level.
  • Ensure the power button is pressed correctly.
• No Control/Loss of Signal:
  • Re-bind the transmitter and receiver.
  • Check the distance between the transmitter and receiver; ensure it's within the operational range (350-400m).
  • Verify all connections between the receiver, ESC, and servos.
  • Check for potential interference sources in the operating environment.
• Incorrect Servo Movement:
  • Check servo reversing settings in the transmitter menu.
  • Verify channel assignments.
  • Inspect servos for damage or mechanical binding.
• Screen Not Responding:
  • Restart the transmitter.
  • If issues persist, consider a firmware re-flash.
