RESET BUTTON
The RESET button can be used to return the Vanguard to its factory default settings. Power-on the unit then promptly
press-and-hold the RESET button. The LEDS will cycle through all red, all off, all amber, all green. During the all green
phase, the RSSI LED will turn red to show that the configuration is being reset to defaults. Once the LEDs flash all green
3 times, release the RESET button and proceed as normal.
