Why is the transmitter distance for my KERUI G18 Security System shortened?

  Danielle PriceAug 8, 2025
  The transmitter distance for your KERUI Security System might be shortened due to: * A nearby emitter sending signals, so find and eliminate the interfering source. * Insufficient power supply to the host's standby battery, therefore check if the power supply is plugged in well. * If the above steps don't work, it could be that the host receiver has stopped working.

  If the remote controller for your KERUI Security System isn't working, it could be due to several reasons: * The coding is unmatched with the host; try re-coding. * The remote controller has insufficient power; change the battery to one of the same type. * The battery pieces have poor contact or are corroded; eliminate any dirt caused by corrosion on the pieces.
