Documents
Not all documents referred to in this document are part of the scope
of delivery for the equipment. Xstrahl reserves the right to determine
the documents delivered with the product.
Compatibility/Contra
indications
Xstrahl X-Ray Therapy Systems must be used only in combination
with components expressly recognised by Xstrahl as compatible with
Xstrahl X-Ray Therapy Systems. Before using any equipment or
component not supplied by Xstrahl, consult Xstrahl for advice on
compatibility.
The use of components other than those specified by Xstrahl may
affect electromagnetic compatibility (EMC) performance and result
in increased emissions or decreased immunity of the equipment.
Modification of
Equipment
Changes and/or additions to Xstrahl X-Ray Therapy Systems must
be performed only by persons expressly authorised by Xstrahl. Such
changes must comply with best engineering practice and all
applicable laws and regulations within the jurisdiction.
Any modification during the service life of the equipment requires
evaluation to the requirements of EN60601-1 and EN60601-2-8.
Environmental
Conditions
Xstrahl systems are designed to be operated and stored within the
following environmental conditions:
Ambient Humidity
Storage Temperature

Note:
Ensure the shipping box for the system and generator are stored
upright and the boxes are not stacked at any time.
Electromagnetic
Compatibility
The Xstrahl Radiotherapy systems are suitable for use in a clinical or
hospital environment, within a suitable lead shielded treatment room
(for relevant X-Ray radiation protection).
Xstrahl has declared the following essential performance when
subject to electromagnetic emissions or RFI immunity:
Treatment Mode
X-Ray beam can carry on running and complete the correct
treatment
X-Ray beam can be interrupted or stopped
X-Ray beam can be interrupted and error messages are
visible
Electronic component failure prevents the X-Ray beam from
running
Standby Mode
X-Ray beam cannot be run
Errors can be reported
Power on fail LCD will still read with power off
WARNING: Use of Xstrahl equipment adjacent to or stacked
with other equipment should be avoided to prevent improper
operation.
WARNING: Equipment spare parts, cabling and accessories
should only be replaced with Xstrahl specified parts to prevent
increased EMC emissions or decreased immunity of the
Xstrahl system.
WARNING: Portable RF communication equipment
(example; antenna cables or antennas) should be used no closer
than 30cm to any part of the Xstrahl system
Portable Personal
Electronic Devices
Portable personal electronic devices (intravenous pumps, cardiac
pacemakers, intravenous devices and other implanted devices)
should not be placed in front of a radiation beam. Small doses of
radiation could cause the devices to malfunction. Failure to observe
this warning could cause these devices to malfunction which could
result in serious injury or even death. Always monitor the operation
of portable personal electronic devices during radiation treatment.
Intended Audience
The information contained in this manual is intended solely for the
use of trained and competent medical operators preferably trained by
Xstrahl or an authorised person. Training requirements vary by

iv
country. Operators must ensure that training is provided in
accordance with all applicable local laws and regulations
Training
All operators must have the required training before attempting to
operate the Xstrahl X-Ray Therapy System. Because countries have
different regulations for training, the operator must be compliant
with the local laws and regulations of the jurisdiction in which the
equipment is installed.
Warnings and Cautions
All potential hazards to the health of personnel and to the integrity of
Xstrahl’s equipment are presented as Warning and Caution notices.
All Warning and Caution notices in this manual will appear at the
point of application.
Sample Warnings and Cautions:
WARNING: Warnings alert operators to potential hazards to
personal health and safety. Each warning explains
the nature of the hazard, states the means by which
the risk can be avoided and explains the
consequences of failing to observe the warning.
CAUTION: Cautions alert operators to the potential risk of
damage to the equipment or the environment, but not of hazards
to health and safety. Each caution explains the nature of the
hazard, the means by which the risk can be avoided and explains
the consequences of failing to observe the caution.

Quality Assurance
The Xstrahl 150 defines the exposure in time and does not measure
the output of the X-Ray tube for each exposure conducted. The
output of each clinical energy needs to be measured during the
acceptance of the unit and schedule in the daily quality assurance
conducted on the machine.
The IPEM report 81, kilo voltage X-Ray units recommends that the
following quality control checks are conducted on superficial
systems
