a), Trigger the flashlight separately (without flash transmitter) because there is very sensitive light senser on this receiver.
b), Trigger the flashlight with the CTR-301 transmitter together.
c), 1/4 stand Tripod screw hole can be mounted into the tripod, ballhead, and so on.
d), Trigger the vedio flash via the PC cable ( The little plug is 2.5mm, the big plug supports 6.35mm standard vedio flash jack).

It`s new version of CTR-301, which called CTR-301P. We designed it with PC sync port according to the most of customers` request, we replaced the previous " TEST " bottom to the PC port. you can mount the flash directly on this receiver or hanging it down on the light stand where it can be connected via the PC sync port. It`s very helpful for you.
