HEAT

In addition to the TENS/EMS/Massage programs, the EM 89 Heat also offers two heat levels which can be activated as required for all programs; see “Starting use” section. The heat supplied via the gel pads relaxes the muscle and improves circulation. You can activate the first level of the heat function by pressing the Heat button. Then wait a moment until the temperature stops increasing. If the temperature is too low for you, you can activate the second level of the heat function by pressing the Heat button again. If you would like to deactivate the heat function, you can do so by pressing the Heat button again. If you want to use the heat function separately, without additional stimulation, proceed as follows:

• Step 1: Position the electrodes in your preferred target area (see “Information on electrode positioning” section for positioning suggestions) and connect them to the device. To use the heat function, always apply both electrodes of the channel being used. The channels used are shown on the display.
• Step 2: Press and hold the ON/OFF button for at least one second to switch on the device.
• Step 3: Press the Heat button to access heat function adjustment.
• Step 4: Use the adjustment buttons to select your preferred treatment time and press the ENTER button to confirm your selection.

THERAPY MEMORY

Your device records the treatment time in the therapy memory. This allows you to record how long you have been using the device in total or for a specific period of time for your treatments. This may be helpful when consulting your doctor.

Accessing the therapy memory

To access the therapy memory, switch the device on using the ON/OFF button and press and hold the button for 3 seconds. The elapsed treatment time appears in the display. The top two numbers stand for hours; the minutes are shown below.

Resetting the therapy memory

ELECTRIC CURRENT PARAMETERS

Electrostimulation devices operate with the following electrical current parameters, 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 setting should be effective but must never cause any 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.

Cycled pulse parameter variation

In many cases, it is necessary to cover the overall tissue structure at the site of application by applying several pulse parameters. In the Digital TENS/EMS device, this is achieved by the provided programs, which automatically make a cyclical pulse parameter change. This also prevents individual muscle groups at the site of application from being affected by fatigue. The Digital TENS/EMS device provides useful preset current parameters. You can change the pulse intensity at any time during use. In 6 programs, you can also set various parameters for stimulation yourself.

CLEANING AND STORAGE

Gel pads

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

Cleaning the device 
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 cleaning of the surface of the device using a cloth moistened with a mild soapy solution.

Storage

• Do not make sharp bends in the connection cables or the electrodes.
• After use, stick the electrodes back onto the carrier foil for the gel pads.
• Store the device in a cool, well-ventilated location.
• Never place any heavy objects on the device.
• In order to achieve as long a battery service life as possible, fully charge the battery at least every 6 months.
