OFF-CAMERA 
TTL FLASH CORD
USER MANUAL 
 

INTRODUCTION
Thank you for choosing a Vello Off- Camera TTL Flash Cord. This 
TTL ash cord allows you to set up a portable  ash for off-camera 
lighting while retaining all of the TTL  ash functionality achieved in 
modern digital cameras. 
Off-camera lighting reduces the harsh shadows of direc t on-camera 
ash and gives your photos more natural lighting. TTL (through the 
lens) functions of modern cameras handle exposure calculations so 
you can concentrate on composing the image. Because the light 
from the ash is measured through the lens by the camera, there is 
no need for exposure calculations or a separate light meter.
 

CAUTIONS
Switch off all devices (cameras 
and ashes) before adding or 
removing a ash unit.
Use caution in stretching the 
coiled cord. Do not stretch 
the cord to lengths where it 
will cause your setup to 
become unstable.
Do not attempt to modify or 
disassemble the cord, shoe, or 
contacts. Do not attempt to 
“daisy-chain” ash cords.
This device is not waterresistant. Do not immerse in or 
expose to water, rain, or snow.
Do not clean the cord with 
solvents. Use a sof t, dry cloth 
to clean the cord and 
connections.
Do not use or leave the device 
in conditions of extreme heat, 
severe cold, or high humidity.
