Introduction
The Orlit ST-RT Wireless RT Transmitter is designed espe-
cially for use on CANON cameras and adds 980ft/300m
of remote freedom, without a speedlight, to provide full
TTL, Remote Manual, and HSS, in 5 individual groups.
The wireless radio protocol is based on the popular
Canon RT radio system employed in the Canon 600EX-RT
speedlite. Using a Orlit ST-RT on the camera’s hot shoe,
a Canon photographer can easily adjust the exposure
for any Orlit Rovelight RT Family Monolights and Orlit
RT600C Speedlites. The transmitter is water and dust
resistant equal to the Canon EOS-1D series cameras.
Before using this transmitter, please read this instruction
manual and familiarize yourself with the manuals of your
camera and flashes you are controlling.
