2-channel FM transceiver for cameras. Includes a receiver and a transmitter. I have confirmed that the receiver powers on, but I haven't been able to test the transmitter because it doesn't have batteries. This is an old product, and I haven't been able to find any information about it online. It's a rare item, but if you know how to use it and are interested, please consider purchasing it. - Product Name: Little Baby Trigger - Type: DC-2 Type - Included: Remote control, receiver, connection cable - Manual: Japanese instruction manual included Thank you for looking.
