CDR Wireless Installation
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
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.
