The Magnet Switch and LED Status Indicator
The Echo
®
Wireless Vibration Sensor is activated by a magnet switch located on the side
of the housing. The exact location of the magnet is etched on the sensor housing. If a
fairly strong magnet is held near the location of the magnet switch, the blue LED light
will begin blinking quickly. If the sensor was previously deactivated it will become
active and immediately take its first measurement. If the sensor was previously active it
will deactivate and no longer take measurements. The blue LED light allows the user to
quickly.
