Information on electrode positioning

It is fundamental to the intended success of electrostimulation applications that electrodes are properly placed. We recommend that you 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. The following applies to the selection of electrode positions:

Electrode spacing

The greater the distance between electrodes, the larger the volume of tissue stimulated. This applies to the area and depth of the tissue volume. At the same time, however, the stimulation intensity applied to the tissue decreases with more distance between electrodes. As a result, greater distances between electrodes mean a larger tissue volume is stimulated, but less intensively. As such, you must increase the pulse intensity to boost stimulation in this case.

The following guidelines apply when choosing the electrode distances:

• Effective spacing: approx. 5–15 cm.
• With spacing of less than 5 cm, the device will primarily apply strong stimulation to surface structures.
• With spacing in excess of 15 cm, large areas and deep structures will be very weakly stimulated.

Therapy memory

The EM49 records the treatment time. To access the therapy memory, switch the device on using the ON/OFF button and press and hold the button for 5 seconds. The elapsed treatment time appears in the display. The top two numbers represent the minutes; the hours are shown below. To reset the treatment time, press and hold the button for 5 seconds. When the batteries are replaced, the therapy memory is automatically reset. Press the MENU button to return to selecting a program, or switch the device off.

Info: The therapy memory cannot be accessed if the Doctor’s function is activated.

Electric current parameters

Electrostimulation devices operate with the following electric current settings, which may affect the stimulation results differently, depending on the setting:

• Pulse shape

  This describes the time function of the stimulating current.  A distinction is made between monophasic and biphasic pulse currents. In monophasic pulse currents, the current flows in one direction, and in biphasic pulse currents, the electrical pulse alternates its direction. The Digital TENS/EMS device only provides biphasic pulse currents as these relieve muscles, cause little muscle fatigue, and offer safer use.

  

• Pulse frequency

  The frequency indicates the number of individual pulses per second and is displayed in Hz (Hertz). It can be calculated by determining the cyclic value for the time period.  The relevant frequency determines which types of muscle fibres react most favourably. Slow-reaction fibres react more easily to lower pulse frequencies of up to 15 Hz, whereas rapid-reaction fibres only respond from approximately 35 Hz up. Pulses of approx. 45–70 Hz are linked with constant tension in the muscles and quicker fatigue. Higher pulse frequencies are therefore better to use for speed strength and maximum power training.

  

• Pulse width

  This indicates the duration of an individual pulse in microseconds.  Among other aspects, the pulse width therefore determines the penetration depth of the electricity, where usually larger muscle mass requires a larger pulse width.

  

• Pulse intensity

  Adjusting the intensity level depends on the individual sensitivity of each user and is determined by a variety of variables, such as site of application, blood supply to the skin, skin thickness and the quality of the electrode contact. The settings should be effective but should never cause an unpleasant sensation, such as pain at the site of application. While a gentle tingling indicates sufficient stimulation energy levels, any setting that causes pain should be avoided. If using the device over an extended period, you may need to adjust the intensity level as your muscles start to adapt to the pulse intensity.

CLEANING AND MAINTENANCE

Adhesive electrodes

To ensure that the adhesive electrodes remain adhesive for as long as possible, clean them carefully with a damp, lint-free cloth or clean the underside of the electrodes under lukewarm running water and pat dry with a lint-free cloth. Before cleaning with water, remove the connection cables from the electrodes. Following treatment, stick the electrodes back onto the carrier foil.

Cleaning the device

• Always remove the batteries from the device before cleaning.
• The number of uses possible depends on the environmental conditions and skin qualities. If the electrodes no longer adhere to the skin properly during use, please replace them.
• Clean the device after use with a soft, slightly damp cloth. If it is very dirty, you can also moisten the cloth with a mild soapy solution.
• Do not use any chemical or abrasive cleaning agents for cleaning.

Ensure that no water enters the device.

Reuse of the device

Once it has been properly prepared, the device can be used again. Preparation includes replacement of the treatment electrodes as well as cleaning of the surface of the device using a cloth moistened with a mild soapy solution.

Storage

• Remove the batteries from the device if you will not be using it for a prolonged period of time. Leaking batteries may damage the device.
• Do not make sharp bends in the connection cables or the electrodes.
• Disconnect the connection cables from the electrodes.
• After use, stick the electrodes back onto the carrier foil.
• Store the device in a cool, well-ventilated location.
• Never place any heavy objects on the device.

Troubleshooting — common problems, error codes, fixes and support

• Common issue: No stimulation or very weak stimulation. Possible fixes: check electrode placement and skin contact, replace or rehydrate self‑adhesive gel pads, ensure cables are fully inserted, and verify battery level (device uses 3 × AAA batteries). If intensity shows low despite correct setup, replace electrodes and batteries and try both channels separately to isolate a faulty lead.
• Problem: Device won’t power on. Fixes: confirm fresh AAA batteries and correct polarity, check battery contacts for corrosion, and ensure battery compartment lid is properly closed; if the problem persists, contact Beurer support for service options.
• Error codes and behaviour: the EM 49 typically indicates low battery via a battery icon and uses an auto safety shut‑off for long idle periods; consult the instruction booklet for any specific display messages related to electrode connection or overload. If the device displays an unexpected symbol or freezes, remove batteries for 30 seconds and re‑insert them, then re‑start. If recurring, contact authorised service.
• Preventive measures: store electrodes on the original film, keep contacts clean, replace gel pads every few months or when adhesion/feeling degrades, avoid using on irritated or broken skin, and follow contraindications in the user manual (e.g., do not use with pacemakers, during pregnancy in certain areas, or over malignant tissue unless advised by a physician).

Warranty and support: Beurer typically provides a manufacturer warranty (varies by region; 2–5 years commonly reported). For repairs, replacement parts or technical help, contact Beurer customer service or the retailer where you purchased the unit—the official Beurer product page and authorised distributors provide warranty registration and local support channels.
