Extended Interface
You can connect your VX-760C to an external power source or PC sync via the extended interface on the side
of the flash.
External power source: An external power source, such as the Bolt Cyclone Battery Pack, can greatly
increase the battery life of your flash and reduce the recycle time in between flashes.
Note: When using an external power source, the AA batteries must still be in the flash in order to operate.
PC Sync: You can synchronize your VX-760C with a camera by running a PC cord between your camera and
the VX-760C’s PC sync terminal. This lets you position the flash away from the camera, thus giving you more
lighting options.
Note: The PC sync terminal on the VX-760C is only for synchronous signal input, and not output.
