INSTRUCTIONS FOR USE - TENStem eco basic
Warning: The product must not be used when operating machinery or during activities that
require a high degree of attention. This applies especially in trac!
Warning: Stimulation in the facial area (trigeminal stimulation) can cause drowsiness, so
you can only resume the stated activities if you no longer feel sleepy. For optimum safety,
you should only carry out stimulation in the facial area when sitting or lying down.
Warning: Do not operate the device in the vicinity of potentially explosive and/or ammable
substances or fumes.
1.3.3 Special safety instructions
Caution: Simultaneous connection of the patient to a medical electrical (ME) device for
high-frequency (HF) surgery can cause burns below the electrodes of the product and result
in damage to the electro-stimulation device.
Caution: Operation immediately next to (e.g. 1 m from) an ME device for short-wave or
microwave therapy may cause uctuations in the product's current pulses (output levels),
which may have painful eects.
Caution: Portable HF telecommunication devices (radio equipment, mobile telephones) (in-
cluding their accessories such as antenna cables and external antennas) should not be used
within a distance of less than 30 cm (12 inches) to the TENStem eco basic (including its
accessories). Non-compliance may lead to inferior device performance or faulty operation.
Caution: Using this device directly next to other devices or stacked on top of them should
be avoided because it may result in malfunctions. If the use as described is nevertheless
necessary, this device and the other devices should be monitored to establish that they are
working properly.
Special instructions for the product’s muscle stimulation programmes
Enzymes (e.g. creatine kinase) and proteins (e.g. myoglobulin) are released during every
muscle strain. In the case of severe muscle strain, but also due to one's constitutional pre-
disposition or in conjunction with certain medications or drugs, certain individuals may ex-
perience more severe muscle breakdown (rhabdomyolysis). In rare cases (especially with
overtrained muscles or pre-existing conditions), the amount of enzymes and proteins re-
leased as well as electrolyte imbalances can also damage internal organs such as the kid-
neys, liver and heart. This risk also exists in the case of electrical muscle stimulation, as it
may constitute intensive muscle training. This risk is generally very rare and, in most cases,
is avoided by observing the information in the following chapter (“Instructions for avoiding
physical overload reactions due to muscle stimulation”). No such harm has occurred to date
with our products.
The muscles can quickly reach their stress limit, especially during the rst training sessions.
This is associated with the risk of muscular overload, which can also occur in healthy and
trained users. Muscular overload may already manifest itself during training through dis-
