Operation Instructions
  • Copy the security code
    1. Hold the original transmitter and 301H-03 head to head
    2. Press the first button of 301H-03 and hold until its red LED bulb blinking.
    3. Press the first button of original transmitter and hold we propose per 0.5 second once.
    4. The 301H-03 red LED will change from blinking to lighting steadily and then goes off. This indicates a successful copy of the security of first button. Now release both buttons. (301H-03 LED blinking >> LED lighting steadily >> LED goes off, now the code has been duplicated from the original transmitter to 301H-03 completely)
    5. Repeat steps 2, 3 & 4 to copy other buttons.

  • Tune 301H-03's frequency
    A. With Frequency Detector (FD)
    1. Put original transmitter on FD. Then press any button of original transmitter to send out a frequency signal, and then release the button. FD will display the frequency of original transmitter.
    2. Open the cover of 301H-03, and put it on FD.
    3. Press and hold any button of 301H-03 ,and use the attached plastic tuner to tune the variable resistor on 301H-03's circuit board.
    4. When the FD displays same frequency as original transmitter, you have completed the frequency tuning. Release the button and replace the 301H-03's cover.

    B. Without Frequency Detector
    1. Open the cover of 301H-03.
    2. Stand in Front of receiver.
    3. Press and hold any button of 301H-03, and use the attached plastic tuner to tune the variable resistor on 301H-03's circuit board.
    4. When the receiver is activated, you have completed the frequency tuning. Release the button and replace the 301H-03's cover.
    5. You may also go to a further distance from receiver and tune finely for a best distance
  • NOTE:
    1. Do not put FD or transmitters on metal surface during any process.
    2. If you fail to copy the security code (the 301H-03 red LED bulb remains blinking or does not go off), change the holding position of both transmitters to "side by side" or other position of "back to back" instead of head to head.
    3. Once the duplication is completed, your 301H-03 will memorize (The frequency and security code even after battery replacement. However, you may also change it for duplication of another transmitter, the frequency can always be changed with the same processes. As for the security code, it can be erased simply by pressing the 3 buttons simultaneously for about 3 seconds. Its red LED bulb will be blinking and then off. Now the 301H-03 is just like a new one and You may copy the new security code.
