This Digital TENS Device features 15 separate programs. In all programs you can set the impulse intensity of each channel individually. You can also set various parameters in programs 13 – 15 to adjust the eect to the application area.

• Patients may experience skin irritation and burns beneath the stimulation electrodes applied to the skin.

• Patients may experience headache and other painful sensations during or following use.

• Patients should stop using the device and should consult with their physicians if they experience adverse reactions from the device. How does stimulation current work? The Digital TENS device works on the basis of transcutaneous (meaning “through the skin“) electrical nerve stimulation (TENS). TENS is a clinically proven, eective, medication-free method of treating certain types of pain which, when used properly, is free of side eects. It is also approved as a means of simple self-treatment. The pain-relieving eect is caused by suppressing the transmission of pain in the nerve fibers (particularly through high-frequency impulses) and increasing the release of the body‘s own endorphins, which decrease the sensation of pain. Every condition that calls for the use of TENS must be clarified by your physician. He or she will also give you information about the specific benefits of TENS self-treatment.

• 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 o 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.11

• 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. recommend- ed output value for the electrodes is 58.1 mA/sq in (9 mA/cm²), an eective 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 o the device, lie down and support the legs in an elevated position (approx. 5 – 10 min).12

• 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 aected by the pain is between the electrodes or position one electrode directly on the area aected 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 aected by pain or use them in conjunction with the electrodes of the first channel to restrict the area aected 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. WARNING Exclusively use the electrodes on skin that is clean and preferably free from hair and grease, in order to extend the lifecycle of the elec- trodes. Worn electrodes may cause skin irritations as they can no longer ensure an even distribution of current. We recommend replacing the electrodes after having used them a maximum of 20 times. If the electrodes partially detach before they have been used 20 times, replace them at an earlier stage. For more information on where to purchase replacement electrodes, see page 8.16 TENS Program Table NOTES: TENS programs 1-12 can’t be customized- see below. Electrode positions should surround the area aected by pain. In the event that groups of muscles cause pain, group the electrodes around the aected 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).

• The device shuts o if it is not in use for two minutes (automatic shuto). When the unit is switched on again, the LCD screen displays the menu selection and the most recently used menu flashes.

12. 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.20

Interference may occur in the vicinity of equipment marked with the following symbol: NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reflection from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site sur

vey should be considered. If the measured field strength in the location in which the EM 44 is used exceeds the applicable RF compliance level above, the EM 44 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the EM 44.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.64 Subject to error and change758.876-0617 Table 3 Guidance and manufacturer’s declaration – electromagnetic immunity The EM 44 is intended for use in the electromagnetic environment specified below.
