Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The CARINA
Digital Intraoral Sensor, used with a compliant computer, is intended for
TM
use in the electromagnetic environment specified below. The customer or the user of the
CARINA
Digital Intraoral Sensor should assure that it is used in such an environment.

NOTE 1 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
The ISM (Industrial, Scientific and Medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to 6,795
MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur
radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4
MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 4,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to
21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
a
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the FI-XRS systems used exceeds the applicable RF compliance level above, the CARINA
be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the CARINA
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m

The CARINA
TM
Digital Intraoral Sensor is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the sensor
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the sensor as recom-
mended below, according to the maximum output power of the communications equipment.
