Introduction:
1. The remote trigger for studio flashes and outdoor flash is used as the controller of synchronous trigger studio flash of cameras. It consists of a signal sender and a receiver trigger and works by means of the frequency modulation wireless remote control.
2. The signal transmitter adopts the advanced circuit and components, and can transmit the coded FM wireless signal. The circuit of the transmitter has the function of standby and hibernation, thus it has low power consumption; the products can work under the standby mode for more than one year with only one battery; continuously trigger for thirty thousand times. The trigger current is only 0.01MA, which will definitely cause no damage to the flash contact of the camera. The transmitter is applicable to the traditional or digital camera with hot shoe or PC controlling interface.
3. Receiver trigger adopts dry battery for power supply, which is safe, energy-saving, and convenient. The product adopts micro-computer for controlling the decoding, which has superior anti-interference capability; sensitive reaction speed, the highest synchronous speed can reach 1/250sec.
4. All the models of the product uniquely have the multi-frequency isolation technique and the self coding matching function by users. Users can freely match and use the sender and the receiver according to the demands, which have 16 isolated channels to suit for specific shooting environments. Triggers set in different channels can be combined to work or independently work but do not interfere with each other in an efficient distance.

Operation：
How to use:
1. Insert the transmitter's hot shoe socket into your camera's hot shoe jack, plug the flash onto the receiver, and switch ON the receiver. Make sure the channel selector of both transmitter and receiver at same channel. Press the Test button on the transmitter to test before shooting.
2. If your camera does not have hot shoe socket for connecting the transmitter you can connect the transmitter to the camera by the PC Sync Cord provided. (Only the old camera needed).
3. You can trigger both the flashgun and studio lights with this flash trigger. If you use the receiver on big studio strobe flashlight or AC slave flash, you can just connect the receiver to the studio strobe flashlight with 3.5mm or 6.35mm jack plug PC Sync cord(not included).
4. Incompatible: Canon 2000D, for Sony Minolta hot shoe,etc.
