The Meike MK-RC7 allows you to use a remote radio link for firing the flash in manual mode. 

It has a transmitter and receiver that both have a shutter release button and connections to other elements.

The transmitter can be used in three different ways: 

1.- Mounted in the socket of the camera: When shooting the camera causes the shot of the elements connected to the receiver. 
2.- Connected to the camera by sync cable (PC). When shooting the camera causes the shot of the elements connected to the receiver. 
3.- Use as a remote control. When you press the button the shot of the elements connected to the receiver is activated. When you push the button half way, you initiate the autofocus on the camera which is connected to the receiver, and reactive if the flashes are in low power mode. The switch controls the shot either instant or delayed for 10 seconds.

The receiver can be used in three different ways: 

1.- With a flash mounted in its socket. 
2.- With a flash of study connected by cable. 
3.- With a camera connected by cable.

In either case when you press the shutter release button of the reciever, the connected devices go off instantantly. When pressed half way the autofocus is initiated on the camera connected to the receiver, and reactive if the flashes have been in low power mode.
