B, The wireless remote control parameters 1, Working voltage: DC3V, 2 pcs CR2032 battery. 2, Transmitting frequency: 314-16MHz 3, The transmit power: <10dBm 4, Standby current: <5uA C, Using 1. The device is a Wireless remote control 2. The chip CMT2219A acts as FSK transmitter, the crystal oscillator is 26MHz 3. The remote control is mainly composed of four parts: keys, FSK modulation unit, microcontroller, and an antenna. It has 2 key buttons. Press and hold both button more than 3 seconds, the remote powered on, while the LED indicator lights. Then press and hold on the key of "DOWN" or "UP", it will trigger high frequency FSK modulation unit to transmit the ID code and key value. The high-frequency signal emitted by the antenna. When the remote control has been powered on, press and hold the both button more than 3 seconds, the remote control is turned off, while LED is off. If there is no key operation within 50 seconds, it will automatically shut down. This device complies with part 15 of the FCC Rules.
