Page 5: Important Information
Intended Use The Trigno Wireless EMG Systems are battery-powered biofeed- back devices intended for research, investigational and scholarship purposes only. Delsys products are not intended for measurement ® purposes or for use in the treatment and diagnosis of disease. Inter- pretation of the EMG signal by a qualified professional is required. -
Page 6: 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 7: Device Information
93/42/EEC. Class I device, Annex VII. Type BF device (IEC 60601-1) Isolated device, (Class II, IEC 60601-1) Do not dispose this product with house waste. Contact Delsys Inc. for instructions on responsibly disposing this device. This product should not be mixed with other commercial wastes. - Page 8 Changes not expressly approved by Delsys Inc.could void the User’s authority to operate the equipment To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radi- ated power (EIRP) is not more than that required for successful com- munication.

Page 12: Power Supply
Power Supply Trigno Systems are equipped with an isolated medical grade power supply. The green power LED on the base station will illuminate when power is connected to the Base Station. The power supply is provided with interchangeable country-specific plug adapters. The power supply can be conveniently stored in the Base Station storage space when the system is not in use. -

Page 14: Charging The Sensors
Once the software is correctly installed, the PC will automatically detect the Trigno Base Station when connected to the USB port. Charging the Sensors Before using the system, the sensors should be fully charged by placing them in the Base Station cradle slots. Ensure the Base Sta- tion is powered and that the green power LED is illuminated. -
Page 15: Acquiring Data In Emgworks Acquisition
Acquiring Data in EMGworks Acquisition Refer to the “Acquiring and Plotting Data” video tutorial (provided on the DVD) for a brief introduction to configuring the EMGworks software with the Trigno system. This and additional EMGworks tutorials can be found on our website. Refer to the EMGworks documentation (accessible in the Help menu of the software) for detailed instructions on setting up data collection in EMGworks. -

skin, minimizing motion artifacts and the ill-effects of line interference. To ensure a strong bond with the skin, it is advised to remove excessive hair and wipe the skin area and the EMG Sensor with isopropyl alcohol to remove oils and surface residues. Allow the skin to dry completely before applying the interfaces. -

hosts the sensor pairing function and can send an “off” command to all sensors. A compact display of this information is accessible in EMGworks by hovering over the notification area icon for the Trigno hardware. The full dialog is displayed by double-slicking this icon. Figure 8. -
Page 19: Using The Analog Outputs
Using the Analog Outputs The Trigno System provides simultaneous analog signal reconstruction of data being detected by all active sensors. These signals are made available on the 68-pin connectors located on the Base Station. EMG signals at these outputs are amplified by a factor of 909, with full dynamic range of 5V. -
Page 20: Screw Terminal Connections
Screw Terminal Connections Many data acquisition systems are equipped with screw-type wire terminations. In these cases Delsys can supply a cable assembly that mates with the analog output connectors and breaks out the individual channels onto single conductors. Please contact Delsys for details regarding this particular wire assembly or other connectivity needs. -

Page 28: Additional Sensor Information
Additional Sensor Information Sensor Pairing Trigno sensors communicate with a custom wireless protocol that links each sensor to a unique Base Station. This linking process is known as sensor “pairing”, and is initiated through the “Pair” command. Trigno systems are shipped with all sensors appropriately paired. Sensor pairing is typically needed if sensors are being replaced within the network group, when the communication frequency sets are changed, and after a firmware upgrade is performed. -
Page 29: Sensor Factory Calibration
Delsys. Factory calibration data are a string of numbers and letters which encode the calibration values for a specific sensor. -
Page 30: Smart Sensors
Smart Sensors After pairing, the association of sensors to the base station is retained 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” button in the “Add Sensors” pane in EMGworks. -
Page 31: Using Tandem Trigno Systems
Using Tandem Trigno Systems Two Trigno systems may be used in tandem, connected to the same computer as a synchronized 32 sensor, 128 channel system. Initial Connectivity To use two Trigno systems in a tandem configuration, connect the USB cable from each base station to the same computer. If using EMGworks, also connect the Trigger Cross-Over Cable (DC-C02) between the trigger ports on the two base stations. -
