Current Parameters; Pulse Shape - Beurer EM 80 Gebrauchsanweisung

• Do not expose the device to direct sunlight or high temperatures.
• Protect the device from dust, dirt and humidity. Never submerge the device
in water or other liquids.
• The device is suitable for private use.
• For reasons of hygiene, the electrodes should only be used on one person.
• If the device is not functioning properly, or if you start feeling unwell or
there is any pain, stop the application immediately.
• To remove or move the electrodes, first switch off the device or the appro-
priate channel in order to avoid unwanted irritation.
• Never modify any electrodes (e.g. by cutting). This leads to a higher cur-
rent density and can be dangerous (max. recommended output value for
electrodes: 9 mA/cm , an effective current density over 2 mA/cm² requires
2
greater attention).
• Do not use when asleep, when driving a vehicle or at the same time as
operating devicery.
• Never use with any activities where an unforeseen reaction (e.g. increased
muscle contraction despite low intensity) may be dangerous.
• Make sure that no metallic objects such as belt buckles or necklaces can
come in contact with the electrodes during stimulation. If you wear any
jewellery or piercings (e.g. belly piercing) near the application site, you must
remove these before using the device as burning may otherwise occur at
some points.
• Keep the device away from children to prevent any hazards.
• Do not confuse the electrode cables and contacts with your headphones or
other devices, and do not connect the electrodes to other devices.
• Do not use this device at the same time as other equipment which sends
electrical pulses to your body.
• Do not use it near any highly flammable substances, gases or explosives.
• Never use accumulators, always use the same types of battery.
• In the initial minutes, carry out the application sitting or lying down in order
to avoid any unnecessary risk of injury in the rare event of a vagal reaction
(feeling of weakness). If you start feeling weak, switch the device off im-
mediately and put your legs up (approx. 5-10 minutes).
• It is not advisable to apply any enriching creams or ointments to the skin
beforehand, as this greatly increases electrode wear or else unpleasant
current spikes may occur here.
Damage:
• If the device is damaged, do not use it if you are in any doubt but rather
contact your dealer or the customer service address indicated.
• Check the device at regular intervals for signs of wear or damage. If you
find any such signs or if the device was used improperly, you must bring it
to the manufacturer or dealer before it is used again.
• Switch off the device immediately if it is defective or if is not working
properly.
• Do not, under any circumstances, attempt to open or repair the device
yourself! Only have repairs carried out by the customer service department
or an authorized dealer. If these instructions are not heeded, the warranty
becomes null and void.
• The manufacturer assumes no liability for damage caused through impro-
per or wrong use.
Information on ESD (Electrostatic Discharge)
Please note that jacks marked with the ESD warning label must not
be touched.
ESD protective measures:
– Do not touch plugs/jacks marked with the ESD warning label with fingers!
– Do not touch plugs/jacks marked with the ESD warning label with handheld
tools!
Further explanations on the ESD warning label, as well as possible training
courses and their contents, are available on request from the customer
service department.

3. Current parameters

Electrical stimulation devices operate with the following current settings,
which will alter the stimulation effect depending on the setting.

3.1 Pulse shape

This describes the time function of the excitation current,
whereby monophase pulse trains are differentiated from
biphase. With monophase pulse trains, the current flows
in one direction. With biphase pulses, the excitation cur-
rent alternates its direction.
