MECHANICAL Installing or Changing the Battery On the back panel is a 9 volt battery compartment. To install or change the battery simply press down on the designated area and slide the cover in the direction indicated. Clip on the new battery, place the battery in the compartment and replace the cover, snapping firmly into place. Either a disposable or rechargeable battery may be used. If using a disposable, an alkaline battery is recommended for longer life. A fresh alkaline battery will have 15-20 hours of useful life. Use only a battery, do not use a linepowered adapter.
ELECTRODE CONNECTIONS Electrode Types There are several electrode types which may be used with the TR-10. The size and location of the target muscle often determines which type of electrode to use. The standard electrode used with the TR-10 has three electrode contacts in one foam pad and snaps directly to the preamplifier.
Attaching the Electrodes Snap on a disposable electrode to EMG A. The preamplifier has 3 snaps; 2 labeled ACT for Active and 1 GND for Ground. The disposable electrode must be completely snapped into all 3. Important: Prepare the skin by wiping the area with an alcohol pad and then wiping it dry with a tissue or cloth, to avoid high impedance artifact by removing oils and dead skin. The most common reason for inaccurate readings is insufficient cleaning of the skin. Remove the backing on the disposable electrode to expose the adhesive surface and adhere fully to the skin. The two active electrodes must be placed parallel to the muscle fiber.
17
Pathway TR-10 Operator’s Guide
Lead Wires Lead wires may be used to connect to three individual electrodes when necessary to aid small muscle placements. For more information see Preamp Adapter. Contact The Prometheus Group for any of these electrodes. The use of any other electrodes is not recommended. Warnings: • Discontinue use if any irritation occurs. • Long term air exposure will result in drying of gel. Keep unused electrodes sealed in bag. • Prepare skin by wiping area with alcohol pad. Allow to dry before applying electrode. • Use electrode only with Pathway EMG unit. • Use only on clean unbroken skin. Do not re-use. • Do not connect preamps, electrodes, lead wires or any other component to wall outlets, line-powered adapters, or any other electrical connection! Do not leave electrodes attached to the preamp when the device is not in use.
Preamp Adapter The preamp adapter is used to interface the preamp to different styles of electrodes. It has lead wire connectors to accept standard electrode lead wires. Please contact The Prometheus Group for any adapter or electrode requirements.

DISPLAY Front Panel LED Indicators The TR-10 uses LED indicators to display information. These LEDs are labeled with their meaning or values. Some indicators are used for more than one function such as displaying EMG level and goal level or goal type. The TR-10 uses 4 individual LED indicators and one Bar Graph Display.
Status Indicators The TR-10 has 4 LED indicators labeled BATTERY, WORK, REST, and GOAL SUCCESS. These are used to show information about the current state. The BATTERY indicator lights during start-up while showing battery level on the bar and begins blinking during operation if the battery voltage drops too low. The WORK and REST indicators light when the unit is in the work/rest timing mode. The WORK LED will light when in a work period and the REST LED will light when in a rest period. The GOAL SUCCESS indicator lights when goal success is achieved.
Bar Graph Display The bar graph display is used to show the current levels of EMG A by lit LED's based on the scale from 1 to 800 microvolts. When a goal is set the goal value is also shown on the bar graph by one lit LED. The lower section of the bar graph is also used to display goal type selections. These goals will be explained in the individual sections to follow. Selections made on the bar graph are shown in the following manner. The current selection is shown by a flashing LED. As will be described, these alternative choices can be made by pressing the A key.

Pathway TR-10 Operator’s Guide
OPERATION Start-up Sequence The thumbwheel switch turns the TR-10 on and adjusts the volume level. When first turned on, the TR-10 will sound a several second tone which may be used to adjust the speaker volume to a comfortable level.
Battery Level Indication During Start-up During this start-up tone, the current battery voltage is indicated on the Bar Graph display while the BATT LED indicator is lit. The top of the display indicates a new battery. As the battery voltage drops during its lifetime the level indicated on the display will drop as well. The bottom of the display indicates that the battery is at the end of useful life and should be replaced. Battery indication on start-up: BATT

Pathway TR-10 Operator’s Guide
Feedback Mode and Display Range Indication During Start-up After showing the battery level, the Bar Graph Display on the TR-10 will now show the current feedback mode and display range setting. The current goal type is AUDIO: CONTINUOUS and the current range is 800.
The Training Displays After the start-up sequence is completed, the Pathway TR-10 will automatically display EMG activity. The current level of EMG activity is shown by the illuminated LEDs on the bar graph. The values are shown on the scale immediately to the right of the EMG A bar for the normal display range. Although only 20 LEDs are used the TR-10 uses 2 levels of brightness and lights pairs of LEDs to show 4 times as many levels. For example the following sequence is used between 2 LEDs: STEP 1 STEP 2 LED 2: OFF HALF ON LED 1: FULL ON FULL ON
STEP 3 FULL ON FULL ON
STEP 4 STEP 5 FULL ON FULL ON HALF ON OFF
The next step after step 4 is the same as step 1 but is 1 LED position up the display. Note that this sequence is an analog representation which gives an excellent feeling of the values in between the LEDs. When this display is combined with the normal EMG value changes, it shows the EMG levels just as if there were 80 LEDs in each bar! During a training session the bar shows the EMG level of the A channel. Note that increasing muscle activity will moves the LED's up and decreasing activity moves the LED's down.
Displaying EMG To observe the operation of the display, apply the electrode to a convenient area such as the forearm, as described in Attaching the Electrodes. Note how the moving bar display ascends and descends, as the hand and wrist muscles are contracted and relaxed.
21
Pathway TR-10 Operator’s Guide EMG is essentially a logarithmic function so this type of scaling is used for the moving bar display. As a result, the movement of the bar relates directly to the change in muscle activity. The total microvolt scale is 1 to 800 microvolts RMS.
Expanded EMG Display Range The TR-10 has an expanded display range where the Bar Graph Display is used to show from 1 to 30 microvolts instead of the normal 1 to 800. This is graphically illustrated:
800
30
30
1
Normal Display Range

Expanded Display Range
The expanded display range is useful when EMG activity remains at very low levels. When only the bottom few LED’s are being illuminated in the normal display range, using the expanded display range will use more of the Bar Graph Display and provide improved visual feedback to the patient. The top of the Bar Graph Display represents 30 microvolts when using the expanded display range. The Bar Graph Display uses same type of logarithmic scaling used in the normal range. This scaling can be seen in the section Expanded Display Range Scale on the next page. If the EMG activity exceeds 30 microvolts and goes off the scale, the top LED will remain illuminated to show full scale has been achieved.
22
Pathway TR-10 Operator’s Guide
Expanded Display Range Scale The labeled microvolt values on the scale immediately to the right of the Bar Graph Display are for the normal display range. These labeled values no longer apply when in the expanded display range. The actual microvolt values for the expanded display range are seen here:
23
Pathway TR-10 Operator’s Guide Setting the Display Range Press the A key once to check the current settings on the TR-10. The EMG activity will temporarily be suspended while the display shows the current display range (either 800 or 30) and the current feedback mode. The current range is indicated by a flashing LED next to the 800 or next to the 30. Use the up arrow key to select the 800 microvolt display range and the down arrow key to select the 30 microvolt display range. Here we see the 800 microvolt display range: 800 30 When the desired display range is indicated on the Bar Graph, do not press any keys and the display will return to EMG activity with the selected range.
Setting the Feedback Mode The A key is used to set the feedback mode for EMG A. By pressing the A key once, the current mode will be momentarily displayed on the EMG A bar graph. In this case the display will indicate that no goal is set by flashing the AUDIO: CONTINUOUS LED:
AUDIO: CONTINUOUS ABOVE BELOW WORK / REST 5/10 5/5
To change the mode simply press the A key again until the LED next to the desired mode is flashing. When no keys are pressed for a few seconds, the TR-10 will return to the real-time EMG display with the selected goal type and timing mode enabled.
24
Pathway TR-10 Operator’s Guide Feedback and Timing Modes Feedback mode choices are: 1) AUDIO: CONTINUOUS -- audio feedback (pulsed tone proportional to EMG Level); continuous session 2) ABOVE -- audio feedback when contracting above goal; continuous session 3) BELOW -- audio feedback when relaxing below goal; continuous session 4) WORK/REST: 5/10 -- work/rest sets of 5 seconds work and 10 seconds rest; above tone goal 5) WORK/REST: 5/5 -- work/rest sets of 5 seconds work and 5 seconds rest; above tone goal
Goal Display When one of the goals is enabled, one LED on the bar will be illuminated. The position of this goal LED in the display represents an absolute microvolt goal at the corresponding labeled value for the normal display range. If the goal is the LED labeled 20, the goal is set at 20 microvolts for the normal display range. In the expanded display range, the goal level is indicated relative to the expanded display scale. To set an absolute microvolt goal, use the normal display range to set the goal level to the desired labeled value and then return to the expanded display range. Goals are active only in a continuous session or a work period. If a goal is set at 20 microvolts and the EMG level is higher than the goal the display should look something like:
■
■
EMG LEVEL
GOAL
If an ABOVE goal is selected and the EMG activity meets or exceeds the goal, a pulsed tone will be heard. This pulsed tone will have a rate which is proportional to the current level of EMG. The GOAL SUCCESS LED will also be lit (unless in a rest period).
25
Pathway TR-10 Operator’s Guide Setting the Goal Value When a tone goal type is initially selected, the default goal value is 10 microvolts. To change the goal value, the up and down arrow KEYS are used. Note that the bar still shows the current level of EMG activity, so that goals can be changed without interrupting the training session. Also note that the goal value is always displayed relative to the current microvolt display range. To change the goal value, simply press the appropriate arrow key until the desired goal is reached. Use single key presses to increment or decrement the goal value, or hold the key down for larger changes. The position of the goal LED will change to reflect the current value. While changing the goal value the goal LED will blink on the bar graph display. When the desired goal value is displayed, do not press any keys and the TR-10 will return to normal operation. Important: The goal value is displayed relative to the current microvolt display range. The scale labeled to the right is for the normal 800 microvolt display range only. To set an absolute microvolt goal, use the 800 microvolt display range to set the goal level and then set the 30 microvolt display range.
Work/Rest Intervals The TR-10 may be put in the work/rest timing mode if a series of short contractions rather than one long session is desired by the clinician. In this mode the TR-10 cycles between work periods and rest periods. When the TR-10 is in a work period the WORK indicator will light and when the TR-10 is in a rest period the REST indicator will light. There are two work/rest timing modes to choose from: 5/10 or 5/5. 5/10 yields a work time of 5 seconds and a rest time of 10 seconds, and 5/5 yields a work time of 5 seconds and a rest time of 5 seconds. Important: In the work/rest timing modes the goal is always an above tone type of goal. This goal is only active during the work periods, although it is still shown during the rest periods. The success tone and GOAL SUCCESS indicator only become active during work periods. To return to the continuous mode select AUDIO: CONTINUOUS, ABOVE, or BELOW. The unit will now be in the continuous session mode.
