  • This product operation keyboard has 15 ppt keys, 0 – 9 number keys, 10, “++” and “–” keys adjust the frequency to use, and also generate emission output behavior.
  • Press the “++” or “–” key to add 1KHz or lose 1KHz to the primitive frequency output. Press and hold “++” or “–” for more than 1 second, continuous or continuous reduction will occur.
  • The scanning mode is 1 KHz at 35 MHz – 138 MHz; 10 KHz at 138 MHz – 550 MHz; 100 KHz at 550 MHz – 4000 MHz.
  • To end the scan, simply press the “++” “–” button or the “OK” button. The “OK” button is the output control button. Click to launch, and press again to stop the transmission.
  • The launch behavior caused by “++” or “–” requires two “OK”s to end the launch behavior. This product is on the upper right of the display when there is output emission behavior.
  • The corner will appear “>>”, the “C” button will end the emission and the frequency will be zero.
