To lockout a false alert, (X, K or Laser only) press the mute button three (3) times, (either on the detector or the SmartCord®) during the alert. Pressing the mute button the first time will silence the audio. Pressing it a second time will generate a prompt on the display that will read: "Lockout?" Press it a third time to confirm that you want to lock this signal out by location and frequency. A "Stored" message will be displayed.
