I. Product Features 1. Operating frequency: 315 MHz / 433.92 MHz (special frequencies can be customized according to customer requirements); 2. Battery type: button battery 2032*1; 3. Working method: copy; 4. Shell material: ABS; 5. Product size: 76*35*16mm (including shell); 6. Product net weight: 21.54g (including shell and keychain). II. Function Description 1. Copy code operation: Press the single button of the copied remote control and the copy remote control at the same time, until the copy remote control indicator flashes from fast to steady light, indicating that the copy is successful, then release the two remote control buttons. Other keys are also operated in sequence in this way until all keys are copied. 2. Code clearing operation: Press and hold the lock and unlock buttons of the copy remote control at the same time until the indicator light flashes quickly, and then short press the unlock button three times to clear the code (the lock button has been held down during this process). 3. Recovery code operation: Press and hold the mute and ring buttons of the copy remote control at the same time until the indicator light flashes quickly, then you can restore the previously cleared remote control code. III. Parameters Working voltage DC2.4V3V Quiescent current 0.1uA Emission current 11mA Transmit power 36dBm Working temperature -20-70 Duplicate chips: 2260, 2262, PT2264, 5326, SC5262, HT600, HT680, HT6207, HT6010, HT6012, HT6041, SMC918 series, 527, 1527, 2240, HCS101, HCS200/HCS201 (part of code), HCS300 code), part of the microcontroller. IV. Precautions 1. The working voltage cannot exceed the working voltage. 2. In an environment with relatively large wireless interference, the transmission distance may be reduced. 3. Keep it out of reach of children. 4. It is forbidden to use it in a humid environment, otherwise it may cause damage to the remote control. includes: 1 *Remote Control
