transmitter is to be attached on your camera while the receiver an external flash. When the
transmitter is activated, it emits radio signal to the receivers and therefore triggers the

that you have enough receivers to work with them.
The transmitter is made of advanced electronic circuits and components. Its special

mode or triggers 20,000 times continuously. Triggering current is only 0.01mAh. It is safe
for all cameras, both film and digital, and flashes with standard hot shoe or PC sync
connector.
The four selectable channels and advanced anti-interference feature allow the device to
work within the effective area without interfered by other channels.
