"There are two ways of handling remote photography with the Pentax. Wireless or wired. The Pentax Wireless Remote Control System allows one photographer to do the work of several. It consists of a transmitter, which shoots out a short infrared beam, and any number of receivers, which can be used to activate remote cameras, flash units or even motor drives. Maximum control distance is 60 meters in daylight (farther at night) and the system can transmit and receive on three different channels, for individual control of several receivers from a single transmitter. The transmitter can be mounted on an LX hotshoe, so that the camera’s shutter release activates the signal, or it can be controlled separately."
