 Extended Interface

Extended Interface

You can connect your VS-570P 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 VS-570P with a camera by running a PC cord between your camera and 

the VS-570P’s PC sync socket. This lets you position the flash away from the camera, thus giving you more 
lighting options.

Note:

 The PC sync socket on the VS-570P is only for synchronous signal input, and not output.

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 Bolt BO-1011 power cable (sold separately) into the external 

power source socket.

B.  For PC sync, plug a PC cord into the PC sync socket.
