compliance with standards according to which the device has been manufactured.
In particular:
➢The lead section of the cable network must be at least 1mmq.
➢The length of mains cable must NOT be greater than 2m.
•Leads with an insufficient section or an excessive length or both do not guarantee
the safety of the electrical components.
•As quoted in standard EN 60601-1-2 regarding electromagnetic compatibility: “the
use of cable other than those specified in ....... may increase emissions and reduce
the immunity of the device”.
▪Do not use adaptors, multiple sockets or extensions to connect the device to the
mains.
▪Do not place heavy or sharp objects above the power cord in order not to damage
it.
▪Do not place the device next to heat sources or expose it to direct sun light. Install
the device in an adequately ventilated room.
▪Do not install the device in rooms with rapid temperature excursions or where
humidity, dust, chemical vapors and vibrations are present.
▪For information concerning electromagnetic interferences, refer to following
paragraphs. Avoid installing the device close to potential sources of
electromagnetic interferences (like portable or mobile radio-communication
devices or medical devices that generate electromagnetic energy for therapeutic

Easytech s.r.l. –Genu Iso/Plus User’s Manual  rev. C Pag. 9di 97
and diagnostic purposes) which would exceed the limits recommended in the
standards and thus affect the immunity of the device.
▪For information on how to perform maintenance, calibration and regular inspection
operations, refer to Chapter 7.
2.3WARNINGS CONCERNING USAGE

2.4WARNINGS REGARDING ELECTROMAGNETIC INTERFERENCE
Genu-ISO and Genu-PLUS devices do not produce electromagnetic energy for
therapeutic purposes or for their internal functions. Having been manufactured in
compliance with current laws and regulations, they generate a minimum amount of
electromagnetic energy only, similarly to other electronic devices that are not used for
communication purposes. Therefore, they generally cause no disturbance to other
devices or produce radiations that could be potentially harmful for people, that is the
patient, operators and other people.
Inversely, Genu-ISO and Genu-PLUS have also been manufactured so that they are
immune from the disturbances produced by other systems, upon condition that these
are also compliant with standards and that, if they do emit electromagnetic radiations
(for therapeutic or telecommunication purposes), they are maintained at an adequate
distance in order to avoid interferences.
