5. Operating Instructions
5.1. Power On/Off
Press and hold the POWER button to turn the unit on or off.
5.2. Setting Channels and IDs
The VC-818TX operates on a 2.4G wireless system with 8 channels and 30 IDs to prevent interference. To set:
- Press the SYNC/CH button to enter channel setting mode.
- Use the control dial to select the desired channel (1-8).
- Press the SYNC/CH button again to switch to ID setting mode.
- Use the control dial to select the desired ID (1-30).
- Ensure your remote flash units are set to the same channel and ID as the controller.
5.3. Group Control (A, B, C)
The controller supports three independent groups (A, B, C) for flexible lighting setups.

5.4. Flash Modes (TTL, Manual, Strobe)
Press the MODE button to switch between the following flash modes:
- TTL (Through-The-Lens): Automatic flash exposure based on camera metering.
- Manual (M): Allows manual adjustment of flash power output (e.g., 1/1 to 1/128).
- Multi (Strobe): Fires a series of rapid flashes during a single exposure for creative effects.
Use the control dial to adjust parameters within each mode.
5.5. High-Speed Synchronization (HSS)
The VC-818TX supports 1/8000s high-speed synchronization, allowing you to use flash at shutter speeds faster than your camera's native sync speed. This is ideal for freezing fast motion or using wide apertures in bright conditions. Ensure your camera and flash units also support HSS.
5.6. Auxiliary Focus Function
The controller includes an auxiliary focus assist light to help your camera achieve focus in low-light conditions. Activate this feature by pressing the MODEL/AF button.
