1. Overview 1.1. Purpose The CDR Wireless Sensor, Base Station, and application software are elements of an electronic imaging system that transmits X-ray dental exams over a wireless RF link. The Wireless Sensor is powered by a single battery, enclosed in protective packaging. The Base Station is powered from the computer’s USB port. 1.2. Indications for Use The CDR Wireless Sensor system is intended for any dental practice that uses X-ray equipment for intraoral diagnostic purposes. It is indicated for patients receiving intraoral dental X-ray examinations and produces digital images that can be displayed, enhanced, printed, and saved. Because of the Sensor's higher sensitivity to X-rays in comparison to film, the radiation dose to the patient is reduced. For diagnostic purposes, digital images compare favorably with images acquired with X-ray film media. 1.3. Important Setup Reminders 1. Images acquired with your Wireless Sensor are transmitted to the Antenna / Receiver over RF link. If active during image transmission, other devices that use radio frequency or microwave technology (wireless Local Area Networks, wireless telecommunication devices, microwave ovens) may interfere with the optimal performance of your CDR Wireless System. For best results, turn off other wireless or microwave devices when using your Wireless Sensor. 2. Correct placement of the Antenna / Receiver with respect to the Wireless Sensor is essential. Be sure to follow the positioning information found in this document when establishing the optimal location for the Antenna / Receiver. As a general rule, place the Antenna / Receiver as close as practically possible to the patient chair where the Sensor will be used. The distance between the Sensor and the Antenna / Receiver should not exceed 6 feet (1.8 meters). 3. As with any X-ray procedure, stabilizing the Sensor in the correct intraoral position is critical for diagnostic quality images. Equally important is for the patient to remain completely still as X-ray images are acquired. Wireless Sensors are more sensitive to motion during the imaging process, so be sure to remind your patients as you take X-ray images. CDR Wireless User Guide B1051301 Rev. - (DRAFT) 1
1.4. General Description Hardware in the CDR Wireless Sensor system performs the following actions. • Wireless Sensor -- Captures the image created when the Sensor is exposed to radiation from an X-ray source. • Base Station Antenna / Receiver -- Receives, via wireless RF link, the image acquired from the Wireless Sensor and sends it to the USB Interface Unit. The unit is powered from the computer’s USB port. • Base Station USB Interface -- Communicates, via wired USB link, with attached computer hardware, enabling acquired images to be displayed on a computer monitor or other display system. The unit is powered from the computer’s USB port.

CDR Wireless System PC Workstation 4 B1051301 Rev. - (DRAFT) CDR Wireless User Guide
2.1.1. Wireless Sensor The Wireless Sensor provides FM digital data to the Antenna / Receiver over the 2.4 GHz frequency band. Three, user-selectable channels are available to minimize interference in practices where multiple Wireless Sensors are in use. Power for the Wireless Sensor is provided by a water resistant, non-rechargeable battery package located on the back (non-active pixel area) of the Sensor. Battery status is displayed on the Sensor using a single window, dual LED display. (For more information about the Wireless Sensor LEDs and their indications, refer to Error! Reference source not found..) Battery level information is also available in the Wireless Monitor dialog box (Figure 6), where RF channel, signal strength, and Sensor information can be found. PLEASE NOTE: When detached from the Sensor, place the battery pack on its back with the terminals facing upwards. Ensure that no conductive object contacts the battery terminals to eliminate accidental discharge. The Sensor ON / OFF switch is part of the battery package. Turn the Sensor on and off by pressing lightly on the button shown below. The Wireless Sensor must be turned ON to capture X-ray images. The Sensor will turn itself OFF automatically if no X-ray exposures are detected for approximately 15 minutes. For steps on attaching the battery pack to the Sensor, refer to Error! Reference source not found.. Battery Contacts ON / OFF Switch Figure 2. Wireless Sensor with Battery Pack Removed CDR Wireless User Guide B1051301 Rev. - (DRAFT) 5
2.1.2. Base Station Antenna / Receiver The Base Station is composed of the Antenna / Receiver and USB Interface. The Antenna / Receiver receives the radio frequency status and image data signals from the Wireless Sensor, demodulates the signals and transfers the information to the USB Interface. When the Antenna / Receiver is receiving data, the LED located near the base of the Antenna illuminates. The Antenna / Receiver can be positioned separately from the USB Interface to enhance signal reception. Nominally, the Antenna / Receiver should be within 6 feet (1.8 meters) of the Wireless Sensor and facing the patient for best results. The Antenna can be pivoted forward-and-back and rotated from left-to-right to achieve optimum reception. The Antenna / Receiver and USB Interface are shipped connected directly to each other ("docked"). Two screws are used to secure the units. Remote mounting of the Antenna / Receiver from the USB Interface is optional, and may be prompted by a number of factors (including physical layout of the office and / or RF reception). The base of the Antenna contains molded areas to allow for wall- and ceiling-mounted options. When the Antenna / Receiver is mounted remotely, the two screws securing the Antenna / Receiver to the USB Interface are removed allowing the two units to be unplugged from each other. A standard computer network modular Category 5 cable with RJ-45 connectors is then used to connect the Antenna / Receiver to the USB Interface. Figure 3. Antenna / Receiver 6 B1051301 Rev. - (DRAFT) CDR Wireless User Guide
2.1.3. Base Station USB Interface The USB Interface connects the CDR hardware to the computer via a standard USB 1.1 port. It also provides channel selection for Wireless Sensors, performs Sensor diagnostics, and supports field upgrades of the firmware for the unit itself, the Antenna / Receiver, and Wireless Sensors. When opened, the translucent compartment lid permits access to the Sensor cradle (used for RF channel configuration and diagnostics) and a storage slot for a battery pack. When closed, the compartment lid serves to protect the Sensor and battery pack when not in use. Dual LEDs are located on the exterior of the USB Interface and supply power and status information about the unit and the Wireless Sensor currently in use. LED indications have several states (On / Off / Blinking) to reflect various states of operation. For more information about the USB Interface LEDs and their indications, refer to Error! Reference source not found.. The USB Interface can be wall-mounted, either "docked" with the Antenna / Receiver itself, or located some distance from the Antenna, via Category 5 cable with RJ-45 connectors. Figure 4. USB Interface CDR Wireless User Guide B1051301 Rev. - (DRAFT) 7
2.1.4. PC Workstation The PC workstation connects to the USB Interface via compatible USB cable and serves as host for CDR software and CDR utilities. In addition, the workstation provides the capabilities to display, manipulate, store, and print images acquired with CDR Wireless hardware.
