2 SAFETY ASPECT
WARNING: Please read this chapter thoroughly.
NICAL devices comply with the related safety requirements; furthermore
it supplies all information necessary for a correct use and the warnings
related to danger associated with x-ray generating units.
NICAL, can not be held responsible for:
,
• use of NL different from the intended one as described in this
manual;
• damages to the device, to the operator, to the patient, caused either
by wrong installation or maintenance procedures, different from
those described in this manual and in the user manual supplied with
the unit, and by wrong operations;
• mechanical and/or electrical modifications performed during and
after the installation, different from those described in the manual.
Any technical intervention must be performed by NICAL qualified
technicians.
Only authorized personnel can remove the covers and/or have
access to the components under voltage.
2.1 Warning
The NL series monitor must be connected to an EN/IEC 60601-1-1
approved power supplier which must be connected to ground.
This device has not been designed to be used in environments where
vapors, anesthetic mixes flammable with air, or oxygen and nitrous oxide
can be detected.
Avoid pouring water, even accidentally, or other liquids into the device,
as this could cause short-circuits.
Before cleaning the device, please disconnect it from the line voltage.
Though this product has been designed with a quite acceptable
protection level from electromagnetic interference, it is advisable to install
it at a certain distance from electrical energy transformation rooms, from
static continuity units, from portable receiving-transmitting units for
Rev.2 May 2007 Page 9/28

User/Service manual
amateur use and for cellular use. Cellular telephones are only admitted
at a distance of more than 1, 5 m from any component of the device.
Other medical instruments and devices that must be used in the same
installation area of the unit must comply with the Electromagnetic
Compatibility rules in force. Non-complying instruments, of which the
poor protection from electromagnetic fields is well known, must be
installed at least 3 mt away from the NL monitor and supplied by a
different electrical line.
The equipment automatically performs some self-test functions and
therefore is able to detect some anomalous conditions. However,
whenever there are doubts on the performance of the equipment (e.g.
images too clear, too dark or with artifacts), the activity must be
suspended and a NICAL qualified and authorized engineer must be
contacted.
During the use of the equipment, the operator must comply with the
local work safety regulation, in particular with the ones referring to the
use of video terminals.
2.2 Environmental risks and displacement
The NL monitor contains in some of its parts, materials that at the end of
the units life, must be recycled at an approved location.
Particularly the device contains the following materials and/or
components:
• iron, copper, aluminum, non-biodegradable plastic material, glass-
resin for printed circuit board (PCB).
Correct disposal of this product
(Waste Electrical & Electronic Equipment)
(Applicable in the European Union and others European countries with separate
collection systems)
This marking shown on the product or its literature, indicates that it should not be
disposed with other household wastes at the end of its working life. To prevent
possible harm to the environment or human health from uncontrolled waste disposal,
please separate this from other types of wastes and recycle it responsibly to promote
the sustainable reuse of material resources.
Business users should contact their supplier and check the terms and conditions of
the purchase contract. This product should not be mixed with other commercial
wastes for disposal.
