• Immediately disconnect the patient in the case of appearing warning on error messages on the display.
• Sitting or reclining position should be applied to the patients with respiratory disorders or breathing
difficulties.
• Treatment parameters and electrodes placement should be consistent with the medical indications.
• Connect the electrodes to the patient at a time when the device does not generate the electricity to avoid
the risk of electric shock.
• Electrodes should not be placed alongside the carotid artery (carotid sinus), in the area of reproductive
organs, in the lower abdomen and over the internal organs.
• It is prohibited to leave the patients unattended during treatments of electrotherapy.
• It is necessary to take precautions in case of the occurrence of surface metal implants in the spot of
application.
• Do not use electrotherapy at the area of application of surgical staples in the skin, or on tissues protected
with dressings or materials containing metal ions (silver, zinc).
• If it is possible, the treatment polarity should be adjusted so that the negative pole ought to be ”further”
from the heart than the positive one.
• It is not recommended to place electrodes in chest area, as it may increase the risk of ventricular
fibrillation.
• Do not place electrodes on the neck and transcranially for epileptic patients, because stimulation may
cause seizures.
• Unless specifically indicated by a doctor, avoid placing electrodes that form the circuit on the chest and
upper back or crossing over the heart.
• Unless specifically indicated by a doctor, avoid applying electrical stimulation directly on the eyes or
mouth.
• In case of treatment performed near the head, the patient should be in lying position.
• Simultaneous performance of electrotherapy treatments and therapies with the use of high frequency
equipment (diathermy and electro surgery) may result in burns where electrodes are applied.
• Take special care with patients with disturbed superficial sensation.
• It is necessary to use operational and sanitized electrodes. Inadequate choice of electrodes may cause
skin irritations or burns.
• It is recommended to differentiate the electrodes size according to performed treatment in order to do
not exceed the current density:
− 0,2 mA/cm
2
for currents with constant component (unipolar) – galvanic, diadynamic, pulse currents,
unipolar sine surge, tonolysis,
− 2 mA/cm
2
for bipolar currents – TENS, Kotz’, interferential.
Improper selection of electrodes can cause skin irritation and burns.
• Carrying out treatments, where for the applied electrodes it is necessary to set the current/voltage so
that the current density does not exceed 2 mA/cm
2
, may require particular attention of the
physiotherapist.
• Irritation and skin burns may occur during performing electrical stimulation. If such syndromes occur you
are obliged to interrupt the treatment and immediately consult with a doctor.
• It is not recommended to apply unidirectional currents in CV mode due to the possibility of skin burns. It
is necessary to apply CC mode.
• Unless specifically indicated by a doctor, it is not recommended to treat pregnant women with
electrotherapy.
• Special caution must be kept during electrotherapy treatments in children and older people.
Battery use (optional):
• Rechargeable battery UR18650A 5S1P is designed for use only with Astar PhysioGo.Lite range of devices.
• In case of mechanical damage to the battery module, there is a risk of fire, explosion or burns, due to
used lithium-ion cells.
• Do not throw the battery or hit it. Do not heat it or incinerate.
• Do not short-circuit the contacts or disassemble the casing.
• Do not immerse in liquids.
• Operation, storage and transport conditions are presented in chapter 4.2.
