1.Getting Started
1.1. Welcome
Congratulations on your purchase of the world's first wireless direct digital radiography
system from Schick Technologies. CDR Wireless™ Sensors combine enhanced chairside
mobility with the same high level of image quality and practice-building power of our
wired Sensors. Like our wired Sensors, CDR Wireless Sensors are more sensitive to X-
rays than film, meaning reduced radiation for your patients.
1.2. System Overview
The hardware elements of the CDR Wireless system consist of the Wireless Sensor (with
battery pack), Antenna / Receiver and USB Interface units (known collectively as the
Base Station), a compatible PC workstation, and interconnecting cables.

1.5. Important Setup Reminders
1. Images acquired with your Wireless Sensor are transmitted to the Antenna / Receiver
over a 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, run the Real-Time RF
Environment Test for information about potential RF interference, or turn off other
wireless or microwave devices when using your Wireless Sensor. If these devices
must remain on, they will cause less interference the further they are from the
Antenna / Receiver.
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 facing the patient, as close as practically possible to the
patient chair where the Sensor will be used. Optimally, the distance between the
Sensor and the Antenna / Receiver should not exceed 6 feet (1.8 meters). Refer to
Section 6 and Figure 6 for guidelines on antenna positioning.
3. As with any dental 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 examination, so be sure to remind your patients as you
take X-ray images.

4.2. Turning on the Sensor
Please Note: To perform the next step, follow the directions in Table 4 to place the battery
package correctly onthe Sensor .
1. Reconnect the battery pack, following the alignment guides along the Sensor. The
battery pack and Sensor are keyed to each other so that when they are positioned
correctly, the battery pack will slide along the guides and snap easily into place.
2. Press the pushbutton switch located on the battery package to toggle the Sensor on
and off. Sensor battery status and RF channel selection are displayed on the dual
LEDs when the Sensor is turned on. Refer to the CDR Wireless User Guide for
battery status and RF channel codes.
4.3. Positioning the Sensor
1. Place the Wireless Sensor on or close to the patient chair and adjust the Antenna so it
is within line of sight of the Wireless Sensor. Details and illustrations regarding
Antenna placement can be found in Section 6.
2. Turn on the Sensor (if it is not on already) and open the CDR Sensor Monitor. (The
icon for the Sensor Monitor can be found in your System Tray. If the icon is not
present, click on the Sensor Monitor button to display it.)
3. Check the Battery Level, RF Noise, and the Signal Strength values. Pivot and rotate
the Antenna, with the active side (identified by symbol) facing the patient, to achieve
the optimal Signal Strength and lowest RF Noise values in your operatory.
4. Keep in mind that there is no perfect number or percentage. The emphasis should be
on taking X-rays when signal value exceeds RF noise.

5.Using the Wireless Utility
5.1. Introduction
The Wireless Utility is installed during the CDR Wireless Sensor Software setup
program. This tool is used to:
• Select the Sensor and Receiver RF channel
• Perform firmware upgrades
• Perform diagnostic tests
These features are accessible from the Wireless Utility Information screen, a sample of
which is shown in Figure 2.
During normal operation, there is little need to use the utility. It is intended principally
for troubleshooting RF interference or Sensor-to-Receiver communication problems that
result in either no images or images with poor quality.

CDR Wireless Installation B1051302 Rev. B

5.2. USB Interface Test and Upgrade
5.2.1. USB Interface Test Description
The USB Interface Test checks the connection between the USB Interface and the host
computer. During this check, a gray test pattern will appear, which should be reviewed
for clarity and contrast (Figure 3).
A good test pattern will have distinct shades of gray that are easy to distinguish. A poor
test pattern will have random and unrelated lines or other image artifacts. A poor test
pattern suggests a problem with the USB cable, USB port, or possibly the USB Interface
itself.
5.2.2. USB Interface Test Procedure
1. Please close the CDR DICOM program application (if running).
2. Verify that the USB Interface is connected to the host computer.
3. Launch the Wireless Utility and click the Start button.
4. Click the USB Interface Test interface button.
5. After a momentary pause, a test pattern is displayed. The orange indicator on the USB
Interface blinks as the test pattern scrolls.
5.2.3. USB Interface Upgrade Description
Field updates to the USB Interface can be accomplished by installing new USB Interface
firmware and new USB Interface CPLD firmware.
5.2.4. USB Interface Upgrade Procedure
1. Please close the CDR DICOM program application (if running).
2. Verify that the USB Interface is connected to the host computer.
3. Launch the Wireless Utility and click the Start button.
4. Click the USB Interface Read info button and check the USB Interface info box.
5. If the Firmware revision version is in red letters, click the Upgrade firmware button.
6. If the CPLD firmware revison is in red letters, click the Upgrade CPLD button.
