6. Operation
The FREDORCH F21S offers three control methods:
6.1. Wireless Remote Control
The wireless remote control allows for full-range operation of the machine. It features six main modes and three combination modes. Although there are nine preset modes, each mode allows for free adjustment of speed and distance. You can quickly stop and restart the machine, offering versatile playability.

6.2. Wired Speed Controller
For direct control, connect the wired speed controller to the machine. The mode knob can be twisted half a circle to change modes, while the speed and distance knobs allow for precise adjustment of speed and stroke length. Each instruction requires a quick 180-degree rotation of the knob. Avoid operating too quickly on each instruction.

6.3. Mobile APP Control (WeChat Mini Program)
The machine can be controlled via a WeChat mini-program, compatible with both Android and Apple systems. To use:
- Ensure your mobile phone's Bluetooth and location services are enabled.
- Open the WeChat app and scan the QR code provided in the product manual (or search for the mini-program).
- Click the plus sign (+) to search for the device.
- Enter a desired device name and a 6-digit password.
- Once connected, you can access three main interfaces: Remote Control Mode, Programming Mode, and Free Mode.
Notes for APP:
- The APP remote control interface functions similarly to the physical wireless remote, offering various modes and speed/distance adjustments.
- The programming interface allows you to input specific values (0-15 for speed/distance, 1-999 for times) to create custom movement patterns. You can save these patterns to your phone for future use.
- The free mode is a test mode where you can drag a finger on the screen to control the machine's movement. This mode operates at low speed due to data transmission limitations.
- If the connection fails, exit and re-enter the program.

7. Maintenance

- Keep the machine clean and dry. Wipe down with a soft, damp cloth after each use.

8. Troubleshooting
- Machine not running: Check if the power supply is properly connected and if the machine is re-energized after any error. The servo motor + PLC control board may require re-energizing if an error occurs.
- APP connection issues: Ensure Bluetooth and location services are enabled on your phone. If connection fails, exit and re-enter the mini-program.
- Unexpected movement: Review the selected mode and programming settings. Familiarize yourself with each mode's behavior to prevent unintended movements.
