Features:high sensitivity, good accuracy, effective distance, signal persistence for a long time.the transmitter and receiver for one-to-one encoding, so that its anti-interference ability.the appearance of the remote control material using glass fiber reinforced nylon material, has a strong acid corrosion,
high and low temperature and water and dust resistance.with emergency stop mushroom head, plus two direction function keys.a strong voltage self-test function, when the transmitter voltage is less than 2.2V when the transmitter is slowly flashing
red light tips, the voltage is less than 1.8V transmitter can not work.Up / down can be set to normal, Na jump, whether to suppress each other.
