Trigno Quattro, Duo, Mini EMG Sensor User’s Guide

Sealed Enclosure
The environmentally sealed enclosure protects the electronics from the ingress
of liquids and other environmental elements and provides a high standard of
user safety and durability.
Internal Magnetic Switch
The Trigno sensors are equipped with an internal magnetic switch which is used
to turn the sensors “on” and to perform RF pairing operations. To activate the
internal magnetic switch, the sensor must be placed on the magnet lock label
located on the Base Station charging cradle. The internal magnetic switch will
only react when the sensors are undocked from the charger or when the
software is performing an RF pairing operation. Exposure to any magnetic fields
outside of these 2 qualifying conditions will be ignored by the sensor. The
internal magnetic switch is a feature which removes the need for a mechanical
button and improves sensor durability and performance. Common household
magnets can be used to perform these functions as well.
Sensor LED Feedback States
Trigno Avanti sensors indicate their status through various LED Arrow colors
