• Using 315 MHz Frequency, the maximum control distance can be up to 25 meters. The receiver has a safety delay and one minute power shut-off to efficiently protect the screen motor. The manual switch is simply and easy to use. The receiver's circuit board is able to store up to 1 million signal codes: it is secure, reliable and cannot be duplicated. The random coding will prevent signal interference. Along with an exceptional range of control, the interface has no directional restrictions and can be easily replaced/relearned (using a universal remote control).
• When learning functions, the radio frequency (RF) wireless remote control systems utilizes a single chip.
