Battery and Charging Dock Safety Information
Before using the battery and charging dock dedicated to CareRay wireless detector, read all applicable
warnings and cautions. Not following these instructions could result in electrical shock, fire, explosion
or other conditions which may cause death, injury or property damages.
Warning: Do not use other batteries that are not the dedicated battery for the detector.
Warning: Do not use other charging docks that are not the dedicated charging dock. Use of
nonstandard charging dock may result in battery explosion or leak.
Warning: Do not operate the charging dock using any type of power supply other than the one
indicated on the rating label.
Warning: This detector configures a plug-in battery. Do not modify or change the inner battery,
otherwise the battery may damage or ignite.
Warning: The change of battery must be operated by a qualified engineer.
Warning: Use the dedicated charging dock. Otherwise, a battery explosion or a battery leak may occur,
resulting in fire or electrical shock.
Warning: Stop using the battery immediately if it emits smoke, a strange smell, or otherwise behaves
abnormally.
Warning: Do not expose the battery or charging dock to water or other liquids.
Warning: Do not attempt to use a battery that has deteriorated. Using a battery that has exceeded its
life cycle may lead to overheating, fire or explosion.
Warning: Remove the battery from the detector if the detector is not likely to be used for an extended
period of time.
Warning: Be sure to charge the battery periodically (once three month) if it is not used for an extended
period of time. The battery cannot be charged if it has been over discharged.
PediatricApplication
Caution: Use of equipment and exposure settings designed for adults of average size can result in
excessive radiation exposure for a smaller patient. Studies have shown that pediatric patients may be
more radiosensitive than adults (i.e., the cancer risk per unit dose of ionizing radiation is higher).
Unnecessary radiation exposure may be harmful to pediatric patients.
Warning: Each request should be reviewed by a pediatric radiologist prior to examination to ensure
the correct study is performed.
Warning: The technologist should adjust the radiation dose for the patient’s size accordingly when
acquiring diagnostic images.

1Overview
The CareView 750Cw/CareView 750C detector is a class of digital X-ray flat panel detector that has an
imaging area of 244mm×307mm. The CareView 750Cw detector communicates with wireless and an
optional wired communication feature (Giga-bit Ethernet communication mode via connecting the
power box).
The detector functions by intercepting X-ray photons. Then the scintillator emits visible spectrum
photons that illuminate an array of photo detectors (a-Si) that create electrical signals. The electrical
signals are then digitally converted to display an image on the monitor.
The detector should be connected to a computer and X-ray generator to digitize X-ray images and
transfer radiography diagnostics.
1.1 Features
Supports wireless communication (IEEE 802.11a/b/g/n) and double frequency (2.4GHz/5GHz) for
CareView 750Cw.
10"x12" cassette-size detector easily fits into standard bucky tray cabinets to upgrade old systems,
while also fitting many general radiography imaging systems.
Designed for portability and stability on uneven terrain with its lightweight design, simple wiring,
rubber-insulated frame, and high-strength aluminum-alloy case.
No not need to be connected to generator due to patented Full-Field Automatic Exposure Detection
(F2AED) Technology.
High capacity battery and low-power operation ensure hundreds of X-ray shots in a single-charge.
1.2 Intended Use
The CareView 750Cw/CareView 750C detector is indicated for digital imaging solution designed for
providing general radiographic diagnosis of human anatomy. It is intended to replace radiographic
film/screen systems in all general-purpose diagnostic procedures. This product is not intended for
mammography applications.
