Page 4: Important Information
Important Information Intended Use The Trigno Wireless EMG Systems are battery-powered biofeed- back devices that enable researchers and clinicians to acquire EMG and related signals from subjects for biofeedback purposes. They are intended for relaxation training and muscle reeducation. Interpreta- tion of the EMG and supporting signals by a qualified individual is required. -
Page 5: Warnings And Precautions
Connect only to Delsys-approved devices. Connecting a patient to high-frequency surgical equipment while using Delsys EMG systems may result in burns at the site of the EMG sensor contacts. Immediately discontinue device use if skin irritation or discomfort occurs. -
Page 6: Device Information
Extended periods in the discharged state may damage the internal lithium polymer cell. Trigno Systems should be stored and operated between 5 and 40 degrees Celsius due to the presence of an internal Lithium Polymer rechargeable cell. - Page 7 Pursuant to Part 15.21 of the FCC Rules, any changes or modifica- tions to this product not expressly approved by Delsys Inc. might cause harmful interference and void the FCC authorization to op- erate this product.

Trigno Base/Recharge Station. Energize the power supply by connecting it to a Mains outlet. Be sure to use the appropri- ate plug adapter for your location. Ensure that the Trigno sensors are properly fitted in the recharge pockets. The sensor LEDs will illumi- nate to amber during charging and green when charge is complete. -
Page 11: Sensor Pairing
Sensor Pairing Trigno sensors communicate with a custom wireless protocol that links each sensor to the active Trigno network This linking process is known as sensor “pairing”, and is initiated through the “Pair” com- mand in EMGworks. 1. Initiate sensor pairing in software. -
Page 12: Smart Sensors
Smart Sensors After pairing, the association of sensors to the Trigno System is re- tained for all future uses. Any configuration in EMGworks can be made to reflect the last paired set of sensors by clicking the “Refresh Smart Sensors”... -
Page 13: Working With The Fsr Membranes
Connecting the FSR Membranes to the Sensor The Trigno FSR Sensor has a connector head hosting 4 receptacles for the membrane transducers. Connect the FSR membranes by to the 4 barrel receptacles taking care to fully mate the plug. The connectors are labeled numbers 1-4 on the sensor, and portrayed in this order in the EMGworks software. -

Page 17: Connecting The Fsr Sensor Analog Outputs
Connecting the FSR Sensor Analog Outputs When paired to a Trigno EMG System, the 4-channel FSR Sensor effectively replaces the EMG channel and 3 accelerometer channels (X, Y and Z) of the standard EMG sensor originally associated with those positions. As such, analog outputs of these channels will output the FSR analog signals. -
Page 18: Specifications
The analog output signal is scaled to full range of the FSR sensor, where an output of 0% in EMGworks corresponds to the most negative output of -4.85V and a full scale output of 100% corresponds to +5.00V. Refer to the Trigno EMG System User’s Guide for ad- ditional details on the analog output specifications.
