1. Remove the belt clip from the unit (if attached).
2. Remove the battery compartment cover on the rear of the device by sliding it in the direction of the arrow.
3. Insert three „AAA“ alkaline batteries in accordance with the polarity markings inside the compartment.
4. Reattach the battery compartment cover. (Fig.1)
5. Attach the belt clip, if desired.
6. Attach the electrodes to the cables. (Fig.2)
7. Insert the plugs of the cables into the sockets on the top of the device. (Fig.3)
Do not pull, twist or make sharp bends in the cables. (Fig.4)
NOTE: When the batteries are replaced or removed, all settings are restored to the factory defaults.
It is important to position the electrodes properly. Consult your doctor to establish the ideal electrode positions for your intended application area. The figure on the display is intended as an initial aid to help you position the electrodes. Refer to the inside of the cover for more detailed information on how to position the electrodes.
Distance Between Electrodes:
The larger the distance between electrodes, the larger the stimulated tissue volume. This applies to the area and depth of the tissue volume. At the same time, however, the stimulation intensity of the tissue falls the farther the electrodes are apart. As a result, greater distances between electrodes mean a larger tissue volume is stimulated, but less intensely. Consequently, you must increase the impulse intensity to boost stimulation. Use the following guidelines to select an appropriate electrode distance:
NOTES:
As part of pain relief treatment, position the electrodes of a channel so that the area affected by the pain is between the electrodes or position one electrode directly on the area affected by the pain and the other electrode at least one inch (2–3 cm) away.
You may use the electrodes of the second channel to simultaneously treat additional areas affected by pain or use them in conjunction with the electrodes of the first channel to restrict the area affected by pain (position electrodes opposite). In this case, position electrodes as crosses.
Always use all four electrodes for optimum treatment.
Use the electrodes on skin that is clean and has as little hair and oil as possible, in order to extend the life of the electrodes. If required, clean skin with water and remove hair prior to treatment.
If an electrode should come loose during use, the impulse intensity of both channels is reduced to the lowest level. Apply the electrode again and reset the desired intensity level.
TENS Program Table
NOTES:
TENS programs 1-12 can’t be customized- see below.
Electrode positions should surround the area affected by pain. In the event that groups of muscles cause pain, group the electrodes around the affected muscles.
To relieve joint pain, surround the joint with electrodes at the front and back as well as on the left and right of the joint, if possible. The distance between electrodes must be 2–6 inches (5 –15 cm).
Figures 25 and 28 apply to knee and ankle joints.
Burst programs are suitable for all areas of application to be treated with changing signal patterns (to minimize having the area become accustomed to the treatment).
NOTES:
1. Select a suitable program from the program tables.
2. Place the electrodes on the desired area for treatment. For positioning suggestions, see the „Positioning the Electrodes“ section. Connect the cables to the main unit. The figure on the display is to help you position the electrodes.
3. Select a program.
a. Press the ON/OFF button to switch on the device.
b. Using the UP/DOWN buttons, select the desired program and confirm your selection with the ENTER button.
4. To return to the previous selection menu, press the MENU button. By holding down the ENTER button, you can skip individual setting steps and start directly with the stimulation treatment.
5. At the start of a session, the impulse intensity of Ch1 and Ch2 is set to 00 by default. No impulses are sent to the electrodes yet. Using the +/- buttons, select the desired impulse intensity (Fig. 3). The impulse intensity of each channel can be set individually.
NOTE: If the program is in a pause phase, the intensity cannot be increased.
6. To end a session early, press the ON/OFF button.
Program 13:
Program 13 is a preset program that you can also personalize. In this program, you can set the impulse frequency between 1 and 120 Hz and the impulse width between 50 and 250 μs.
Program 14:
Program 14 is a preset burst program that you can also personalize. In this program you can set an impulse width between 50 and 250 μs.
Program 15:
Program 15 is a preset program that you can also personalize. In this program, you can set the impulse frequency between 1 and 120 Hz. The impulse width changes automatically during the stimulation treatment.
Custom Function
The Custom Function is a special setting to allow you to access your personal program directly.
Your individual program settings are recalled and activated when the device is switched on.
Setting the Custom Function
If you switch on the device again, the program you saved using the Custom Function is recalled.
Deleting the Custom Function
To clear the device and gain access to other programs again, press and hold the`CH2-´ button again for approx. 5 seconds. To do this, the impulse intensity must be set to 00. Deletion of the Custom Function is confirmed with a long beep.
