Operational Description

FCC ID: U9FREM40 Circuit Description The 433 MHz crystal oscillator drives the base of Q3 the final/buffer amplifier. The modulation provided by IC. The output of Q3 has the matching network consisting of L1, L2 and C1, C2 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source No external antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3 Volt (β€œCR2032” size battery x 1) primary battery Operation Descriptions The transmitter is a remote control operating at 433MHz band. The transmitter is powered by a 3V battery (β€œCR2032” size battery x 1) and the transmitting frequency is crystal controlled. The operation is achieved by different combinations of form pulse modulating signal on the 433 MHz carrier frequency. Remarks: The transmitter is a 7 button transmitter. The EUT continues to transmit while button is being pressed. It is button transmitter, Modulation by IC; and type is Pulse modulation.
