Important Information

Intended Use

e TrignoTM 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. ey are

intended for relaxation training and muscle reeducation. Interpreta-

tion of the EMG and supporting signals by a qualied individual is

required.

Rx ONLY

DO NOT USE on Patients with implanted electronic devices of any

kind, including cardiac pace-makers or similar assistive devices, elec-

tronic infusion pumps, and implanted stimulators.

DO NOT USE on irritated skin or open wounds.

DO NOT USE on Patients with allergies to Silver.

DO NOT USE in critical care applications.

Warnings and Precautions

Consult all accompanying documents for precautionary statements

and other important information.

Consult accompanying user’s guide for detailed instructions.

Keep the device dry. e device is not waterproof and should not be

submerged under any circumstance. e ingress of liquids may com-

promise the safety features of the device. e device is not intended

for use under high sweat conditions. Situations which may result in

the entrapment of sweat around the sensors must be avoided.

Handle with care. Trigno sensors and instruments are precision de-

vices and not designed for excessively rugged use. Carefully inspect

devices prior to each use to ensure that no mechanical deterioration

has occurred.

Sensitive electronic device. Avoid static discharges. Do not operate

or store near strong electrostatic, electromagnetic, magnetic or ra-

dioactive elds. Interference from external sources may decrease the

signal-to-noise ratio or result in corrupted data.

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.

Immediately discontinue device use if a change in the device’s per-

formance is noted. Contact Delsys technical support for assistance.

Delsys Inc. guarantees the safety, reliability, and performance of the

equipment only if assembly, modications and repairs are carried

out by authorized technicians; the electrical installation complies

with the appropriate requirements; and the equipment is used in ac-

cordance with the instructions for use.

Device contains a Lithium-Polymer battery. Do not damage, crush,

4-Channel FSR Adapter User’s Guide6

burn, freeze, heat or otherwise mishandle the device. Recharge only

with the approved power supply and recharger. Sensors should be

charged regularly to extend the battery life. 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. Storing or operating the device, and consequently

the cell, outside of this temperature range may compromise the in-

tegrity and the safety features of the cell.

FCC ID: W4P-SP-W05 (Trigno Sensor)

IC: 8138A-DST02 (Trigno Personal Monitor System)

is device complies with Part 15 of the FCC Rules and Industry

Canada’s RSS-210 License Exempt Standards. Operation is sub-

ject to the following two conditions: (1) is device may not cause

harmful interference, and (2) this device must accept any interfer-

ence received, including interference that may cause undesired op-

eration.

is product complies with FCC OET Bulletin 65 radiation expo-

sure limits set forth for an uncontrolled environment.

Pursuant to Part 15.21 of the FCC Rules, any changes or modica-

tions to this product not expressly approved by Delsys Inc. might

cause harmful interference and void the FCC authorization to op-

erate this product.

To reduce potential radio interference to other users, the antenna

type and its gain should be so chosen that the equivalent isotropi-

cally radiated power (EIRP) is not more than that required for suc-

cessful communication.

is equipment has been tested and found to comply with the limits

for a Class B digital device, pursuant to Part 15 of the FCC Rules.

ese limits are designed to provide reasonable protection against

harmful interference in a residential installation. is equipment

generates, uses, and can radiate radio frequency energy and, if not

installed and used in accordance with the instructions, may cause

harmful interference to radio communications. ere is no guaran-

tee that interference,will not occur in a particular installation. If this

equipment does cause harmful interference to radio or television

reception, which can be determined by turning the equipment o

and on, the user is encouraged to try to correct the interference by

one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into outlet on a separate circuit.

System Requirements

e Trigno 4-channel FSR Sensor is designed to be used with the

Trigno Wireless EMG System.

9TrignoTM EMG System

e Trigno 4-channel FSR (Force Sensitive Resistor) Sensor is an ac-

cessory to the Trigno EMG System designed to provide relative pres-

sure information of body-contact surfaces, such as the heel, the toe

and the ngers. Each sensor transmits 4 independent analog signals,

each servicing an individual FSR membrane. ree FSR membrane

sizes are available for optimizing performance in varieties of scenarios.

One 4-channel FSR Sensor occupies one position of the 16 possible

sensors in a Trigno network. Data are expressed as a percentage of the

sensor’s full scale limits. ese devices are useful for identifying the

timing of signicant events and for making relative amplitude com-

parisons, but are not suitable for making absolute measurements of

force or pressure.

4-Channel FSR Adapter User’s Guide10

Charging the Sensors

Connect the Trigno power supply to the circular DC jack located

on the side of the 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 tted in the recharge pockets. e sensor LEDs will illumi-

nate to amber during charging and green when charge is complete.

e recharge unit will periodically check sensors and apply a top-o

charge to ensure that the battery is kept at full capacity during ex-

tended periods of storage, as long as power is connected.
