Installation and Environment of Use
WARNING The X-ray detector should be installed, maintained, and used by qualified
professional personnel who are trained and qualified in the installation,
maintenance, and use of X-ray equipment.
WARNING The X-ray detector should be mounted onto user-supplied equipment
using the holes provided in the integral flange.
WARNING
Do not operate the X-ray detector in or around flammable gases, gas mixtures,
liquids, chemicals, or other substances. Ignoring this warning may result in
explosion, fire, or electric shock, which may result in severe personal injury,
death, or substantial product damage.
WARNING The enclosure of the X-ray detector must be connected to earth ground
through the X-ray detector grounding lug.
WARNING
Do not connect the X-ray detector to any component or accessory other
than the manufacturer’s specified components and accessories.
Ignoring this warning may result in explosion, fire, or electric shock,
which may result in severe personal injury, death, or substantial
product damage.
WARNING
Do not modify or alter the X-ray detector, its components, or
accessories. Ignoring this warning may result in explosion, fire, or
electric shock, which may result in severe personal injury, death, or
substantial product damage.
WARNING The X-ray detector should not be used as a primary barrier to X-rays.
The user is responsible for ensuring the safety of the operators,
bystanders, and the subjects being X-rayed.
WARNING The X-ray detector is not designed to control X-ray dose. The system
integrator is responsible for controlling the X-ray radiation.
WARNING
The X-ray Detector shall only be used with its approved Varex
Imaging accessories and replacement parts. Product certification and
warranty are rendered void if any alteration to the product is made, or
any instruction, warning, or caution is not followed. It is important
that the X-ray Detector is not directly connected to the hospital
(clinical) network. Connection of the X-ray Detector directly with the
hospital (clinical) network may disturb the IT environment and may
influence the effective data throughput. The imaging workstation and
the WLAN access point must comply with one of the following
standards: IEC 60601-1, IEC 61010-1, IEC 60950-1, or IEC 62368-1.

WARNING
Connection of the X-ray Detector to the hospital (clinical) network that
includes other equipment could result in previously unidentified risk
to patients, operators or third parties. The responsible organization
should identify, analyze, evaluate and control these risks. Subsequent
changes to the hospital (clinical) network could introduce new risks
and require additional analysis.
Caution
Do not operate the X-ray detector in a location with the following
conditions:
•Close to fluid or places where fluid is used
•Close to heat sources, such as a heater
•High temperature environment
•High humidity environment
•High condensation environment
•Extreme cold environment
•Dusty environment
•Salty or sulfurous environment
•Near a vibrating environment
•Environment where there is insufficient air circulation to enable the X-ray
detector and power supply to dissipate heat
Ignoring this caution may result in personal injury or damage to
the product.
Caution
Monitor the temperature of the X-ray detector, and allow the X-ray
detector to cool down when the temperature of the X-ray detector gets
hot. Ignoring this caution may result in personal injury or damage to
the product.
Caution
The temperature at the back surface of the X-ray detector should not
exceed 35ºC when the unit is installed. This may require air flow over
the back surface of the X-ray detector. Humidity levels should be
between 10-90%.

Interface and External Power Supply and Cables
Caution An Image Quality Test or Customer Acceptance test should be
performed before the X-ray detector is used for the first time with
patients.
Note All parts of the X-ray detector are suitable for use within the patient
environment.
Note The X-ray detector is designed to be integrated into a complete X-ray
system by a qualified system integrator. The system integrator is
responsible for obtaining FDA clearance for medical use.
WARNING Be sure to turn OFF the power of the X-ray detector, including turning
off the power supply before servicing, maintaining, connecting, or
disconnecting the cables or accessories.
WARNING
Do not touch the power supply, X-ray detector, cable, connector, or any
other electrical component or equipment with wet hands. Ignoring this
warning may cause electrical shock, which may result in severe
personal injury, death, or substantial product damage.
WARNING Disconnect the cables by pulling on the connector and not the cable
itself. Ignoring this warning may cause electrical shock, which may
result in severe personal injury, death, or substantial product damage.
WARNING
Do not modify the cables or subject the cable to external stress or
damage. Avoid placing anything heavy, including the X-ray detector,
on the cable, stepping on the cable, pulling the cable, or subjecting the
cable to excessive bending or bundling. Ignoring this warning may
cause cable failure resulting in electrical shock, which may result in
severe personal injury, death, or substantial product damage.

WARNING
Do not touch the interface and power supply or cable and the patient
at the same time. Do not let the patient touch the interface and power
supply or cable. Ignoring this warning may cause electrical shock and/
or unknown hazards, which may result in severe personal injury,
death, or substantial product damage.
WARNING
The X-ray detector is not sealed against dripping moisture. All care
must be taken to ensure that moisture does not enter the X-ray
detector. Failure to do so will cause the X-ray detector to fail and/or
cause damage.
Caution
Place the X-ray detector horizontally on a flat, stable surface. If the
X-ray detector is placed vertically or in any tilted position, the X-ray
detector must be securely placed in the Bucky tray or securely fastened
to the X-ray detector enclosure or support structure. Ignoring this
caution may result in personal injury or damage to the product.

Azure 3131Z - 4131Z Reference Manual
REFERENCE MANUAL
1.0 Scope
This document describes design elements and respective interfaces for the Varex Imaging Azure
3131Z and 4131Z Ethernet X-ray detectors. All applicable mechanical, electronic, and software
interfaces are described.
2.0 Intended Purpose
Varex Imaging Azure X-ray detectors and their accessories are designed to be integrated into
systems by X-ray system manufacturers. The Azure 3131Z and 4131Z Ethernet X-ray detectors
are specifically designed to meet the imaging needs of cardiovascular and angiography imaging
applications.
The Varex Image Viewing and Acquisition Pro (Viva Pro) application referred to in this manual
is intended to be used for development, testing, and maintenance purposes only.
Final application and intended use are determined by the X-ray system manufacturer and is
based on the completed X-ray system design. It is the responsibility of the X-ray system
manufacturer to confirm safety, efficacy and compliance of the X-ray system intended for use,
inclusive of the X-ray detector. Manufacturers are responsible for qualifying, validating, and
certifying their products for their intended uses and meeting all applicable regulatory
requirements.
3.0 Contraindication
No part of the X-ray detector is intended to be attached to and/or contact the patient.
4.0 Limitation of Use/Intended Users
The X-ray detector is intended for use by trained and qualified Radiologists, X-ray technicians, or
radiological personnel who are knowledgeable with the use of X-ray detectors, X-ray systems,
and electrical equipment. Installation requires a qualified technician to install and integrate the
detector into the X-ray system.
When used in medical applications, the X-ray detector is for prescription use by a trained
professional.
For USA: Rx
5.0 Audience
This document is for professionally trained users of the X-ray detector, X-ray System
Manufacturers, and X-ray System Installers who are responsible for installing the X-ray detector
into an X-ray System.
Note The system integrator is responsible for obtaining regulatory clearance for
medical use.
