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.

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.

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
6B1051301 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.

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. The recommended system requirements for PC workstations are listed below:
• Compatible operating system (Windows 98, 2000, or XP)
• Minimum of 64 MB RAM
• Minimum of 20 MB free disk space (to install CDR software)
• Minimum of 20 GB free disk space (to store X-ray images you acquire or
convert to DICOM format)
• Available USB port
When connecting the USB Interface to the PC workstation, verify that the USB cable has
a “/2c” designation marked along the cable, typically at either end and close to the
connector. The “/2c” designation is the USB spec designation for power connectors
inside the cable, and is a requirement for this system.
