Electrode Pad Usage

• Do not bend or fold pads. Store pads on the plastic storage sheet when not in use.
• Do not apply ointment or any solvent to the pads or to your skin.
• The pads are pre-gelled and will adhere to your skin.
• Apply the pads only to the skin or to the plastic storage sheet provided.
• Place the pads at least two inches (5 cm) apart on your skin. The pads should never touch each other.
• Always place clean pads in accordance with illustrations provided. Make sure the components are connected properly and the pads are attached to the part of the body you wish to treat.
• Pads should not touch each other when placed onto your skin.
• Do not place on your spine or backbone.
• Pads should not touch any metal object, such as a belt buckle or necklace.
• Pads should not be placed simultaneously on the soles of both feet.
• Pads should not be placed simultaneously on the calves of both legs.
• Do not share pads with another person. This may cause a skin irritation or infection. Pads are intended for use by one person.
• Do not place or relocate the pads while the device is on. Always turn the power off before removing or changing the pad location.
• Do not leave pads attached to the skin after treatment.
• Always pull firmly on electrodes to remove them from the skin to prevent injuries in the unusual case of highly sensitive skin.
• Do not expose the device to direct sunlight or high temperatures.
• Protect the device from dust, dirt and humidity. Never immerse the device in water or other liquids.
• The device is suitable for self-treatment.
• If the device does not work properly, or you feel unwell or experience pain, stop using it immediately.
• Do not modify electrodes (e.g. by cutting them). This increases the current intensity, which is potentially hazardous (max. recommended output value for the electrodes is 58.1 mA/sq in (9 mA/cm²), an effective current intensity beyond 12.9 mA/sq in (2 mA/cm²) requires increased awareness).
• Ensure that no metallic objects (e.g. belt buckles or necklaces) come into contact with the electrodes during stimulation. If you are wearing jewellery or have piercings in the area to be treated (e.g. a navel piercing), these must be removed before using the device. Failure to do so could result in spot burns.
• Make sure not to confuse the electrode cables including contacts with your headphones or other devices and do not connect the electrodes to other devices.
• Do not use the device whilst using other devices that transmit electrical impulses into your body.
• Do not use rechargeable batteries and always use the same battery types.
• During the initial few minutes use the device while sitting or lying down to minimise the risk of injuries as a consequence of isolated cases of vagal responses (feeling of faintness). If you feel faint, immediately switch off the device, lie down and support the legs in an elevated position (approx. 5 – 10 min).

Before First Use

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.

Positioning the Electrodes

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:

• Sensible distance: 2-6 in (5-15 cm).
• At distances below 2 in (5 cm), the unit stimulates surface structures intensely.
• At distances greater than 6 in (15 cm), large areas and deep structures are stimulated very weakly.

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).

To Use

NOTES:

• The device shuts off if it is not in use for two minutes (automatic shutoff). When the unit is switched on again, the LCD screen displays the menu selection and the most recently used menu flashes.
• A short beep sounds when a valid button is pressed. Two short beeps sound when an invalid button is pressed.
• Pause the stimulation at any time by pressing the ON/OFF button. To continue, press the ON/OFF button again and reset the desired impulse intensity.

Care and Maintenance

Adhesive Electrodes:

1. To ensure that the adhesive on the electrodes lasts as long as possible, run the adhesive side under lukewarm water and pat dry with a lint-free cloth. Before cleaning with water, remove the connection cables from the electrodes.
2. Reapply the electrodes to the carrier foil after treatment.

Main Unit:

1. Remove the batteries from the device before cleaning.
2. Clean the device after use with a soft, slightly damp cloth. You can also moisten the cloth with a mild detergent solution. Ensure that no water enters the device.
3. Do not use any chemical or abrasive cleaning agents.

Storage:

1. Remove the batteries from the device if you will not be using it for a prolonged period of time.
2. Do not make sharp bends in the connection cables and electrodes.
3. Disconnect the connection cables from the electrodes.
4. Reapply the electrodes to the carrier foil after use.
5. Store the device and accessories in a cool, well-ventilated space. Never place any heavy objects on the device.

Troubleshooting Guide

Problem: The device does not switch on.

Solutions:

• Ensure batteries have been inserted correctly and are in contact with the terminals.
• Replace batteries, if applicable.
• Contact Customer Service.

Problem: Electrodes do not adhere to the body.

Solutions:

• Clean the adhesive surface of the electrodes using a damp, lint-free cloth. Replace the electrodes if they still do not adhere securely.
• Clean the skin prior to any application; do not use skincare lotions or oils prior to treatment. Shaving may increase the life of electrodes.

Problem: There is no noticeable stimulation.

Solutions:

1. Press the ON/OFF button to pause. Ensure the connection cables are correctly connected to the electrodes and that the electrodes are in firm contact with the treatment area.
2. Ensure the connection plug is firmly connected to the device.
3. Press the ON/OFF button to restart the program.
4. Check electrode positions and ensure that adhesive electrodes do not overlap.
5. Gradually increase the impulse intensity.

• Batteries are weak; replace batteries.

Problem: Unpleasant sensation near the electrodes.

Solution:

• The electrodes are not positioned correctly. Check and reposition.
• The electrodes are worn. This may cause irritated skin because of uneven current across the area. Replace the electrodes.

Problem: Skin in the treatment area turns red.

Solution:

• Immediately stop treatment and wait for the skin color to return to normal. If the redness is directly under the electrode and goes away after a brief time, this is normal and is caused by increased blood flow. Consult your doctor before continuing if the skin irritation persists and is accompanied by an itching sensation or inflammation, as this may be an allergic reaction to the adhesive.
