Preva Installation/Service Manual, 00-02-1577, Revision E01
11
• Mobile RF communications equipment can affect the
performance of medical electrical equipment. (The Preva
Dental X-ray System is not considered life-supporting
equipment.) Midmark advises against using the Preva system
adjacent to other devices. If it must be used near other
devices, carefully adjust their configuration to ensure that
electromagnetic interference (EMI) does not degrade
performance. Test both devices for normal operation. See the
EMC tables on the next two pages for detailed information.
• Use of accessories, transducers, or cables other than those
provided by or specified by Midmark can result in increased
electromagnetic emissions or decreased electromagnetic
immunity of this equipment. This can result in improper
operation.
• Use portable RF communications equipment (including
peripherals such as antenna cables and external antennas,
including cables specified by Midmark) no closer than 30 cm
(12 in.) to any part of the Preva system. Otherwise,
performance of the equipment may be degraded.
• Usage limitation: The Preva Dental X-ray System, when
integrated with ClearVision sensors, must be used with IEC-
60950- or IEC-60601-compliant computers. Also, any device
between the integrated Preva system and the computer (USB
hub) must be compliant with IEC 60950 or IEC 60601. If not,
electromagnetic compatibility may be degraded.
