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.

2.5 Li-Polymer Battery
The battery supplies power to the detector while in wireless connection mode. When operating, only
use the dedicated battery and charge it completely before use. To charge the battery, perform the steps
below.
1Connect one end of 24V DC power cable to the “PORT” of the power box, and the other end to
the DC input port of the charging dock.
2Connect the AC power cable with power box and power supply.
3Insert the battery into the charging dock.
4Open the power switch of the power box. And make sure the power LED of the power box and
charging dock are green indicating the presence of direct current (DC) power.
5Charging should begin automatically. Verify that the charge LED shows a blue light. Once the
battery is completely charged, the charge LED should show a green light.
6Once completely charged, gently pull the charged battery to remove it from the charging dock.

Page 17 of 57
RD-OI-20 A/3
Figure 7 Battery charging
Warning: Remove the battery after the charge LED shows a green light. Prolonged charging after the
battery is completely charged may result in overheating of the battery, causing the battery to explode or
ignite.
Note: Batteries are typically completely charged after approximately 3.5 hours. Time to complete
charge may vary depending on external temperature and remaining battery level.
When the battery is placed inside the detector and the detector is connected with the power box, the
battery will be automatically charged with the charging LED showing orange light.
3System Integration
3.1 System Components
A Digital Radiography (DR) system mainly contains three components.
X-ray generator, tube and subsidiary device
DROC image workstation and software
CareView 750Cw/CareView 750C detector and subsidiary device
3.1.1 Typical Generator Specifications
Energy range: 40~150kVp
mA range: 10~1000mA (depending on the generator power)
ms range: 10~6300ms to produce 0.1~1000mAs (depending on the generator power)
Note: To our best knowledge, the detector is compatible with X-ray generators that match the above
specifications. If you have any questions or concerns regarding compatibility for other generators,
please contact your distributor or CareRay support.

Page 18 of 57
RD-OI-20 A/3
3.1.2 Detector Operation Conditions
X-ray energy range
The detector operates at the following X-ray tube peak voltages:
X-ray tube peak voltages: Min = 40 kVp
X-ray tube peak voltages: Typ = 70 kVp
X-ray tube peak voltages: Max = 150 kVp
X-ray exposure range
The detector operates within the linearity specifications up to an X-ray exposure value of 100μGy.
The detector operates within the degraded linearity specifications above 100μGy and up to an
X-ray exposure value of 130μGy.
X-ray source position
The angle between the X-ray central propagation axis and the normal axis of the front-end
entrance plane taken at the centre point of the matrix should remain within the following range:
X-ray angle: Min = -45 deg
X-ray angle: Typ = 0 deg
X-ray angle: Max = +45 deg
The distance between the X-ray source focal spot and the front-end entrance plane (SID) should
remain within the following range:
SID: Min = 100 cm
SID: Typ = 135 cm
SID: Max = 180 cm
X-ray window duration
While the X-ray window duration can be functionally settled by the system over a wide range,
image quality can be directly impacted by X-ray window duration (due to leakage, noise, or lag).
The full performance of the detector is guaranteed for the following X-ray window range:
X-ray window duration: Min = 10 ms (TBC)
X-ray window duration: Typ = 500 ms (TBC)
X-ray window duration: Max = 2500 ms (TBC)

3.2 X-ray Sync Mode
Synchronous connection mode is the signal transfer mode between the X-ray generator, which sends
the X-ray, and the detector, which receives the X-ray. The sync mode of CareRay’s static detector
contains external sync, software sync, manual sync and F2AED modes.
CareView 750Cw-supported typical sync mode contains software sync, manual sync and F2AED
modes.
CareView 750C-supported typical sync mode contains external sync, software sync, manual sync and
F2AED modes.
Note: The detector can’t terminate x-ray exposure via communication with the generator.
3.2.1 External Sync Mode
The detector and X-ray generator communicates through synchronization cable to deliver a
synchronized exposure signal.
