- Allow the device to charge fully before first use. A charging indicator (if present) will typically change color or turn off when charging is complete.
3.2 Attaching to a Compatible YN Lens
The BR-L1 Remote Controller is designed to attach directly to compatible YONGNUO YN lenses.
- Align the remote controller's mount with the designated mounting area on your YN lens.
- Gently twist or secure the remote controller until it is firmly attached to the lens. Ensure a secure connection to prevent accidental detachment.
3.3 Enabling Wireless Remote Control on the Lens
For the BR-L1 to function as a wireless remote, the compatible YN lens must have its SW (Switch) function set correctly.

Figure 4: SW Function Switch settings on a YN lens. This diagram illustrates how to configure the lens's SW switch for focus mode or wireless remote control.
- Locate the SW function switch on your YN lens.
- To enable wireless remote control, set the switch to the position indicated as "I" for wireless remote control function.
- If you wish to use the lens's SW switch for focus mode (AF/MF), set it to the appropriate position for that function. Note that the BR-L1's remote control capabilities will be active when the lens switch is set to "I" for wireless control.
4. Operating Instructions
4.1 Basic Operation
Once the BR-L1 is attached to a compatible YN lens and the lens's SW function is set to wireless remote control, you can begin operation.
- Power On/Off: Refer to the specific lens manual for powering on the lens system. The remote controller typically powers on with the lens or when a button is pressed.
- Mode Display: The display on the BR-L1 will show 'F' for Focus mode or 'M' for Manual mode, depending on the current setting or function being controlled.
- Controlling Focus: Use the control buttons or dial on the BR-L1 to adjust the focus of the attached lens. The exact function of each button may vary slightly depending on the specific YN lens model.
- Other Functions: The remote may offer additional controls such as aperture adjustment or zoom, depending on the lens's capabilities. Consult your lens manual for full compatibility.
