3.5 mm sync
You can trigger your VD-420 via a PC cord between your camera and the VD-420’s 3.5 mm sync socket. This lets
you position the flash off-camera for more lighting options.
Note: The 3.5 mm sync socket on the VD-420 is only for synchronous signal input.
To access the extended interface, follow these steps:
1. Pull back the contact cover on the side of the flash.
2. Plug the cable into the corresponding socket.
a. For an external power source, plug the appropriate power cable into the external power-source socket.
b. For wired sync, plug a 3.5 mm cord into the sync socket.
