• Pregnancy (especially the first 12 weeks).
• Reduced awareness.
• Dementia.
• Cognitive limitation and/or not independent in “ADL” in
combination with insufcient help from third parties.
Intended parts of the body
The i-Pulz 2 is connected to the body using electrodes which can be
placed on intact, non-irritated and healthy skin over the entire body
except for the contra indicated body parts.
Contra indicated body parts include:
• On damaged or irritated skin/tissues.
• Across or through the head (Trans cerebrally).
• Directly on the eyes.
• Covering the mouth or the lips.
• On the front of the neck (especially the carotid sinus).
• Crossing the heart section.
• From electrodes placed on the chest and the upper back (through
the chest using an anterior and posterior electrode positions, or
other transthoracic applications understood as “across a thoracic
diameter”).
• Application of electrodes near the thorax may increase the risk of
cardiac brillation. Follow placement of electrodes as outlined by
the clinician or pain specialist*.
• Directly over the spinal column*.
* The qualied pain treatment specialist must determine eligibility for
transcutaneous electrical nerve stimulation.
Side effects
In principle, TENS has no side effects. However, electrodes can cause
an allergic reaction. In this case, please contact the supplier of the
electrode. In addition, stimulation can cause a buzzing, tingling or
prickling sensation.
Environment
The i-Pulz 2 is a portable, battery-powered medical device for home
use. It is suitable for indoor and outdoor use. However, take care when
using outdoors as the device has limited waterproof specication. See
chapter Technical Specications for IP rating.The i-Pulz 2 is non-sterile
and does not require a sterile environment.

equipment (cellular phone or microwave) can cause uctuations in
the output of the i-Pulz 2.
• Poorly adhered or small electrodes can cause very unpleasant
stimulation, or even burns if high currents are set. Replace the
electrode in time and check the maximum allowable intensity with
the applied electrode. This can be found in chapter 10.
• Irritation of the skin can be caused by “lengthy” use of small
electrodes and/or an electric current that is too high.
• Keep the i-Pulz 2 out of reach from children.
• Only use the i-Pulz 2 on the advice of a pain treatment specialist;
• A treatment must be interrupted when driving or controlling heavy
machinery. Also while showering, take a bath or swimming.

7i-Pulz 2
effectiveness of the selected therapy.
• Do not wrap cables around the neck as this could lead to serious
injury or strangulation.
• TENS cables should only be connected to electrostimulation
electrodes that are connected to a single person. Never plug the
leads into an electrical outlet or any other electrical device!
• Keep the device away from heat sources, which can damage the
internal battery.
• The i-Pulz 2 has a limited degree of protection against water or
rain. Prevent the device from getting wet.
Maintenance and repair
The i-Pulz 2 stimulator requires little to no maintenance. You can clean
the device with a damp cloth. Never use abrasive or cleaning agents
that could damage or degrade the product.
You can clean the cables with a damp cloth. The use of aggressive
detergents is not advised, because the cables can get damaged or
become rigid, which increases the likelihood of the cables breaking

2 The i-Pulz 2 nerve stimulator
General
The i-Pulz 2 is a two-channel nerve stimulator. There is a channel
on the left- and right side of the device. Both channels work
independently from each other and do not inuence each other – two
different forms of stimulation can, therefore, be used simultaneously. It
is also possible to use only one channel.
The i-Pulz 2 has 12 standard stimulation pre-sets (indicated by P1 to
P12). It is also possible to adapt user specic pre-sets (indicated by
P13 to P15) and to mask them (render invisible). The masking option is
to simplify the use of the device. The i-Pulz 2 will always start with the
last used pre-set and, if set, the last used timer-function as well.
Controls
I-Pulz 2 makes use of touch-technology. The buttons required to
control the device are at the front of the device. At the top is a physical
Power button to turn the device ON/OFF.
