Explosion proof environment
PhysioGo.Lite Electro is not adopted to operation in rooms, where combustible gases or their vapors occur. It is
recommended to avoid anesthetics or oxygen derivate gases, such as nitrous oxide (N
2
O) and oxygen. Some
materials (e.g. cotton, wool) may after saturation with oxygen become combustible at high temperatures
generated with normal operation of equipment. It is recommended that solutions of adhesive and combustible
solvents be vaporized before equipment is operated. It is also recommended to pay attention to the danger of
ignition of endogenous gases. The unit must be separated from the mains before approaching the disinfection
room, where it is installed.
Electromagnetic environment
• Due to the intended use the device can be used in hospitals, clinics, health centers, GP practices,
rehabilitation offices and other health care facilities, under the supervision of qualified personnel.
• Simultaneous operation of unit with devices generating strong electromagnetic field, such as short wave and
microwave diathermies, high frequency surgical equipment, MRI systems, may disturb unit operation. For
this reason, it is recommended to maintain appropriate distance between these devices or to switch off the
generator of strong fields during therapy with the PhysioGo.Lite Electro unit. Manufacturer doesn’t claim
compatibility of the PhysioGo.Lite Electro unit with high frequency surgical equipment.
• If the device is subjected to electromagnetic interference with an intensity that exceeds the compliance
levels declared in section 11.2, the display may be affected, generation may be interrupted or the device
may restart.
• WARNING: Use of the PhysioGo.Lite Electro adjacent to or stacked with other equipment should be avoided
because it could result in improper operation. If such use is necessary, the PhysioGo.Lite Electro and the
other equipment should be observed to verify that they are operating normally.
• It is recommended to use original accessories, spare parts and equipment of Astar.
• WARNING: Use of accessories, transducers and cables other than those specified or provided by the
manufacturer of this equipment could result in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in improper operation.
• WARNING: Portable RF communications equipment (including peripherals such as antenna cables and
external antennas) should be used no closer than 30 cm (12 inches) to any part of the PhysioGo.Lite Electro,
including cables specified by the manufacturer. Otherwise, degradation of the performance of this
equipment could result.
The PhysioGo.Lite Electro meets requirements of electromagnetic interference emission and immunity standards
and shall not pose a threat to correct operation of the other devices. Compliance levels for emissions and
immunity are given in the chapter 11.2.
Operation of touch-sensitive displays

5” with a resistive touch
panel
• Pen designed for resistive screens – preferably with a narrow plastic tip
Admissible:
•
Operator's finger – much lower comfort of operation compared to the pen
Applied parts
The PhysioGo.Lite Electro unit has an applied part of BF type. It includes electrotherapy sockets along with plugs
and patient’s cables.
The elements of the applied part are connected together. Physical contact of the electrodes with patient’s body
during normal use is essential for the device to perform its function.
The specification of the leads, along with the location of the output sockets is described in detail in the chapter
5.1. The appropriate symbol of the BF type applied part is placed on the sockets label.
