Wireless pagers are to safety, miniaturization, wireless coding chip 2262, 1527 working voltage 12V power supply design, working voltage for general 3-13V, but in the parameters of low voltage end encoded output pulse width changes greatly, poor consistency, and the reliability of the decoding is difficult to ensure, heavy rate high, interference probability of large, high voltage battery size and can not reach the design requirements.

Jin Chan wireless call coding system to upgrade continuously, comprehensive use of millions of coding chip, has a group of weight code coding reliability, encrypted transmission, avoid contact with other manufacturers products interfere with each other, calling distance and stable in the empty 300 meters above and in line with the FCC, CE, VCCI and other wireless certification requirements, the encoded output pulse width without power supply change of voltage, wide voltage, high reliability and excellent characteristics.
