Product User Manual
Thank you for purchasing JJC JM-II series wireless remote controller. For the best
performance, please read this instruction carefully before using. You must read it
thoroughly and fully understand this manual to avoid improper operation which may result
in damage to the product.

JJC JM-II Series Radio Frequency Wireless Shutter is designed for most DSLR and
SLR cameras that have a remote socket on the camera body. The system works at
433MHZ frequency and has 16 available channels. What’s more, this wireless remote
system adopts a technology to allow the transmitter to trigger the receiver without direct
line of sight up to 30 meters. The JM-II receiver simply attaches to a compatible camera's
accessory shoe, and then just connect the supplied JJC receiver cable to the camera's
remote socket. The receiver is powered by one piece of CR-2 lithium battery while the
transmitter is powered by one piece of 23A battery. JM-II transmitter can trigger the
camera shutter at five modes: single shot, 5 seconds delay shot, 3 continuous shots,
unlimited continuous shots and bulb shot. The receiver has a 1/4"-20 tripod mount socket
on the bottom, so you can even mount the receiver onto a tripod. Most importantly, our
JM-II transmitter is able to fire multiple receivers at the same time. All these features
make it good for eliminating camera shake in long exposure photography.
