Page 7: Introduction
Introduction Biofeedback is a rapidly developing scientific field that has grown out of advances in physiology, psychology and electronics. Ordinarily, we are unaware of the subtle internal body activities that are part of our everyday lives. Biofeedback uses sensitive electronics to detect and amplify theses activities in order to bring them to awareness. -
Page 8: Installing And Testing Your Battery
Work with EMG and relaxation and tension began during the 1920's and 1930's through the pioneering efforts of Edmund Jacobson. Jacobson found that the more relaxed a muscle was, the lower its EMG activity level was. He also noted that this lowered EMG activity level was associated with a more general subjective sense of relaxation. - Page 9 Fig. 1 Opening the battery compartment Note: Remove old batteries promptly to prevent corrosion. Remove the battery if the device is not going to be used for periods longer than one month. Testing the Battery: To check the battery, turn the unit on, place the threshold potentiometer to 5, and the scale-reading switch to x1.

Page 10: Trying Your Myotrac For The First Time
Trying Your MyoTrac for the First Time Plug the MyoScan sensor into the INPUT jack. Set the switches inside the battery compartment to: OFF, OFF, ABV, NAR (fig. 7). Set the gain switch to the x1 position. Turn the volume up. Set the threshold potentiometer to 10 (fig. - Page 11 Extender Cable (T8720M): Thought Technology's 450mm extender cable can be inserted directly into the sensor head (figure 3), being careful to align the alignment dot on the cable connector with the groove on the sensor head.
- Page 12 The protected pins are designed to prevent any possibility of direct skin contact with the metallic elements that conduct the amplified signals. They also help prevent accidental damage from attempting to plug Thought Technology sensors and encoders to equipment for which they were not designed. ...
- Page 13 Replacement Sensor Cable (Model T9385M) Thought Technology sensors use a highly flexible and lightweight cable. If, for any reason, a break should occur in the cable, a replacement cable is available. Model No.SA9385M To change cables, tightly grip the connector plugged into the MyoScan with your thumb and index, and pull gently on the connector.

Page 14: Front Panel Controls
Front Panel Controls The front panel (see figure 6) includes controls for sound level (VOLUME), threshold level (THR), three gain settings, x1, x10 and x100 for ranges of .08-20, .08-200 and .08-2000 microvolt (V) RMS, respectively. A power switch lets you select OFF and either continuous proportional tone feedback (CONT) or threshold feedback (THR). - Page 15 ABV/BLW: This switch determines if the tone feedback is turned on when the signal exceeds (ABV) or falls below (BLW) the threshold potentiometer setting. CUE TONE/OFF: When either the 4 or 60 second switch is set, and the threshold is exceeded for at least 4 or 60 seconds, a continuous (not proportional) cue tone will sound.

Page 16: Side Panel Jacks
The three threshold switches, LOCK/OFF, CUE TONE/OFF and BLW/ABV are only functional when the front panel power switch is set to THR. Possible combinations are: LOCK/OFF CUE/OFF ABV/BLW Proportional tone feedback above threshold. Proportional tone feedback below threshold. Cue tone when EMG above threshold for > CUE TONE 4 or 60 seconds. -
Page 17: Setting The Threshold Potentiometer
Fig. 8 Side Panel Jacks WARNING: Never connect your MyoTrac to an A.C. powered device! Setting the Threshold Potentiometer The threshold control’s main function is to set a goal value for the EMG signal. When that value is reached, the tone is heard, which provides immediate feedback to reward or inhibit a particular behavior. - Page 18 The Gain setting determines the reading range: 0-20 V at x1, 0- 200 V at x10 and 0-2000 V at x100. For each gain setting, the possible threshold values are: .5-10 V (x1), 5-100 V (x10), and 50-1000 V (x100) respectively. Example of Threshold Setting: If you want to do a feedback session for the purpose of encouraging an increased level of activity in a specific muscle, initially set the...

Page 19: Connecting To A Voltage Monitoring Device
Connecting to a Voltage Monitoring Device Connect the 0-2V output jack (see figure 8) to any instrument capable of reading from 0-2 Volts (digital voltmeter, analog voltmeter, polygraph, integrator, etc.). Make certain the instrument is battery operated or complies with IEC 601-1. The output voltage will always be in the 0-2 Volt range;... - Page 20 Connect and disconnect with care: When unplugging the sensor from the MyoTrac or the sensor cable from the sensor head, be careful to avoid pulling on the cable. Instead, grip the connector firmly and pull straight out. Always make sure to align the notch on the cable connectors (indicated by a dot) with the guiding groove.
