he Advanced®Model BR2 Service Manual
General Description and Purpose
The Advanced®Models BR2 and BR2E
Bilirubin Stat-Analyzer™ Photometers are
dual-arm, dual-wavelength, narrow-bandpass
photometers that measure Bilirubin (TBR)
and Azobilirubin (DBR) absorbance quantita-
tively. The digital readout is calibrated to
read bilirubin in milligrams per deciliter
(mg/dL) for the BR2, or micromoles per liter
(µmol/L) for the BR2E of serum or plasma.
The BR2 wavelengths are fixed and will not
shift during the life of the instrument.
he Service Manual
The BR2 Service Manual contains:
• instructions for performing repairs;
• guides for troubleshooting operational and
mechanical problems;
• circuit system illustrations; and
• information about replacement parts and
service repairs.
This manual is designed to assist
service tec nicians, and does not
imply a license to perform repairs
without proper qualifications.
Service Assistance
To contact Advanced Instruments Product
Service:
• Call (800) 225-4034 (toll-free within the
USA and Canada); after normal business
hours, dial extension 2191
• Call +US (781) 320-9000 (elsewhere)
• Or fax (781) 320-3669
When calling Advanced Instruments, have the
model and serial number from the label on
the back of the instrument, and a description
of the problem. Use a telephone as close to
the instrument as possible in order to facili-
tate making recommended diagnostic checks.
A service technician may assist in making
minor repairs over the phone, providing you
with recommended parts (or part numbers),
or may issue an authorization (RMA) to ship
the instrument for factory repair.
The RMA procedure is as follows:
1. Contact Advanced Instruments to obtain
an RMA.
2. Pack and ship the instrument in its origi-
nal carton. Do not send instrument sup-
ply items.
3. Prepay shipment to the factory.
Advanced Instruments cannot accept col-
lect shipments. Insure the shipment or
accept the damage risk.
Safety
Removing the instrument cover
exposes dangerous 200-250 and/or
100-130 AC voltages. Before remov-
ing the cover, make sure the instru-
ment is turned off and unplugged.
he Advanced®Model BR2 Service Manual

General Cautions
• This product should be operated only with
the type of power source indicated on the
product’s electrical ratings label. Refer to
the installation instructions included with
the product.
• If the power cord provided is replaced for
any reason or if an alternate cord is used,
the cord must be approved for use in the
local country. The power cord must be
approved for the product’s listed operating
voltage and be rated at least 20% greater
than the ampere ratings marked on the
product’s electrical ratings label. The cord
end that connects to the product must have
an IEC 60320 connector.
• Plug the product into an approved ground-
ed electrical outlet.
• Do not disable the power cord’s grounding
plug.
• If an extension cord or power strip is used,
make sure that the cord or strip is rated for
the product, and that the total ampere rat-
ings of all products plugged into the exten-
sion cord or strip do not exceed 80% of the
cord’s or strip’s rating limit.
Safety / Regulatory Information

he Advanced®Model BR2 Service Manual 10
• Route power cords so that they will not be
walked on, tripped on, or pinched by items
placed upon or against them. Pay particu-
lar attention to the plug, electrical outlet,
and the point where the cord exits the
product.
• Do not pull on cords and cables. When
unplugging cords or cables, grasp the cor-
responding connector.
• Do not install or use this product in any
area subject to extreme short-term temper-
ature variations, or locations that exceed
the specified operating environment tem-
peratures.
• Never use this product in a wet area.
• To avoid injury or fire hazard, do not oper-
ate this product in an explosive atmos-
phere.
• Do not install or use the product on an
unstable, non-level work surface.
• Do not operate this product with the covers
removed or unsecured.
Service & Maintenance Cautions
•Unplug the power cord prior to opening or
removing covers, or else you may be
exposed to electric shock, excessive tem-
peratures, or mechanical hazards.
•Performing service or maintenance not
detailed in the User’s Guide, with or with-
out this Service Manual, should only be
done by a qualified service technician.
•Never restrict airflow into or out of the
product. Occasionally, check the air vents
for blockage.
•Wipe the exterior of the product with a
soft, damp cloth as needed. Using cleaning
products other than those specified, may
discolor or damage the finish.
•If the product requires service for any of
the following reasons, unplug the product
from the electrical outlet and refer service
to a qualified service technician.
-The power cord, extension cord, power
strip or power input module is dam-
aged.
-Liquid has been spilled into the interior
of the product.
-A foreign object has fallen into the
product.
-The product has been dropped or dam-
aged by a falling object.
-There are noticeable signs of overheat-
ing or a burning odor.
-The product does not operate normally
when you follow the operating proce-
dures.
-The main supply fuse(s) or any internal
fuse(s) continually fail.
•A discharge of static electricity from con-
tact with the human body or other conduc-
tor may damage system boards or static
sensitive devices. Never perform internal
maintenance without following recom-
mended static protection procedures.
• The product is equipped with operator
accessible fuses. If a fuse blows, it may be
due to a power surge or failure of a com-
ponent. Replace the fuse only once. If the
fuse blows a second time, it is probably
caused by failure of a component part. If
this occurs, refer service to qualified serv-
ice personnel. Always replace the fuse
with one of the same rating, voltage, and
type. Never replace the fuse with one of a
higher current rating.
• When servicing the product, use only fac-
tory-specified parts.
• WARNING: When returning this product
for service, or shipping this product to a
second location, remove all hazardous
specimens and decontaminate the product
before packaging for shipment. If the
product cannot be decontaminated, consult
with your shipping agent on appropriate
packaging and marking.
