Some controls allow for the modification of all the above, others have fixed settings for
current and voltage. Follow the instructions of the x-ray source/generator to set the
desired dose values.
There is a correlation between the distance of the cone to the sensor and the dose received
by the CARINA
TM
unit. The radiation that reaches the sensor decreases with the square
of the distance. If you double the distance, the sensor receives only ¼ of the radiation.
PROPER CARE OF THE CARINA
Prior to taking x-rays, each staff member should be fully trained and have a complete
understanding of how to care for a sensor. Not adhering to the following rules to protect
the sensors may potentially result in malfunction or permanent damage.
• Store the sensor in a safe place when not in use
• Do not allow the patient to bite down on the sensor or sensor cable
• Do not roll over the cable with any wheeled items such as carts or stools
• Do not allow the sensor cable to be pinched in a drawer, door, or cabinet
• Do not twist, coil, or wrap the sensor cable tightly around any object
• Do not insert foreign objects into the sensor or cable connector
• Do not drop the sensor
• Do not clamp the sensor with devices that exert excessive force (for example:
hemostats or clamps of any type)
• Do not autoclave the sensor
• Disinfect the sensor and cable in accordance with the CDC and/or other responsible
regulatory parties including standards such as OSAP for infection control
• Use a new sheath for every patient
Do not autoclave the sensor. Autoclaving a sensor will cause permanent damage.
The sheath must be removed after each patient. The sensor must be cleaned and
disinfected after each patient use by following the Cleaning Agent guidelines. Do not
use any cleaning agents not contained within the approved list of cleaning agents.
Abuse or misuse of the sensor components may result in voiding the manufacturer
warranty. The manufacturer warranty does not cover visible damage to any of
the CARINA
TM
Digital Intraoral Sensor components.
See Care Instructions in Appendix D for more information.
IMAGE QUALITY ASSURANCE
Image quality depends on several factors, such as, but not limited to, the following:
• The quality of the x-ray source (kV, mA, focal spot size, distance to sensor, etc.)
• The alignment of the x-ray source to the anatomical region
• The applied x-ray dose (exposure time)
• The patient not moving during exposure
• The settings of the computer monitor
It is recommended that an operator establishes a procedure for periodic review of
the image quality. If image quality is not satisfactory, or degrading, please check the
contributing system parts and speak with a certified dental x-ray technician or CARINA
Technical Support.

APPENDIX A - EMC INFORMATION
The CARINA
TM
interactions with other electronic devices. Care must be taken when operating this equipment
around other electrical equipment to avoid reciprocal interference. Potential electromagnetic
or other interference could occur to this or to the other equipment. Try to minimize this inter-
ference by not using other equipment in conjunction with this device.
The EMC information in this chapter is provided for the medical system established by connecting
the CARINA
TM
unit to a computer. This computer must be compliant with IEC 60950-1 (if located
outside the patient environment) or IEC 60601-1 (if located inside the patient environment).
Please consult the documentation of the computer for completing the EMC information.
This Medical Equipment is deigned to comply with IEC 60601-1-2: 2014. This equipment gener-
ates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the user instructions, may cause harmful interference to other devices in the vicinity.
However, there is no guarantee that interference will not occur in a particular installation.
Harmful interference to other devices can be determined by turning this equipment on and
off. Try to correct the interference using one or more of the following:
• Reorient or relocate the receiving device
• Increase the separation between the equipment
• Consult your authorized dealer for help
The CARINA
TM
HF surgical equipment and the RF shielded room of an ME system for magnetic resonance
imaging, where the intensity of the EM disturbance is high.
IMPORTANT:
function of the CARINA
may result in image failure or image quality degradation.
CARINA
Sensors are USB compliant devices and shall be used with USB compliant cables
TM
suitable for high speed/USB 2.0 cables. Such cables are either marked "USB 2.0" or "USB High
Speed." USB certified hubs can be used to extend the distance to the USB host/computer.
The length of the cable connection to the hub or between hubs shall not exceed 5 meters.
Use of accessories, transducers, and cables other than those specified or provided by the
manufacturer of the equipment could result in increased electromagnetic emissions or
decreased electromagnetic immunity of this equipment and result in improper operation.
Using non-USB compliant cables or hubs, or exceeding the maximum count of USB
hub devices for extending the distance, can degrade the immunity of the CARINA
unit to electromagnetic fields or increase the emission of electromagnetic fields from
the CARINA
For cable extensions, use a USB Cable Extender (3 feet) or an Active USB Extender Cable
(15 feet).
Use of this equipment adjacent to or stacked with other equipment should be avoided
because it could result in improper operation. If such use is necessary, this equipment
and the other equipment should be observed to verify that they are operating normally.
TM
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 CARINA
degradation of the performance of this equipment could result.
