Note:
Caution:
Danger
serious
personal
injury
This laser product emits invisible infrared laser radiation in the
10.6 µm CO2wavelength band.
Do not allow laser radiation to enter the eye by viewing direct or
reflected laser energy. CO2laser radiation can be reflected from
metallic objects even though the surface is darkened. Direct or
diffuse laser radiation can inflict severe corneal injuries leading to
permanent eye damage or blindness. All personnel must wear eye
protection suitable for 10.6 µm CO2radiation when in the same area
as an exposed laser beam. Eyewear protects against scattered energy
but is not intended to protect against direct viewing of the beam –
never look directly into the laser output aperture or view scattered
laser reflections from metallic surfaces.
Enclose the beam path whenever possible. Exposure to direct or
diffuse CO2laser radiation can seriously burn human or animal
tissue, which may cause permanent damage.

Hazard information
Warning
serious
personal
injury
U.S. customers should refer to and follow the laser safety precautions
described in the American National Standards Institute (ANSI)
Z136.1-2000 document, Safe Use of Lasers. Procedures listed in this
Standard include the appointment of a Laser Safety Officer (LSO),
operation of the product in an area of limited access by trained
personnel, servicing of equipment only by trained and authorized
personnel, and posting of signs warning of the potential hazards.
European customers should appoint a Laser Safety Officer (LSO)
who should refer to and follow the laser safety precautions described
in EN 60825-1, 2001 – Safety of Laser Products.
Warning
serious
personal
injury
Materials processing with a laser can generate air contaminants such
as vapors, fumes, and/or particles that may be noxious, toxic, or even
fatal. Material Safety Data Sheets (MSDS) for materials being
processed should be thoroughly evaluated and the adequacy of
provisions for fume extraction, filtering, and venting should be
carefully considered. Review the following references for further
information on exposure criteria:
ANSI Z136.1-2000, Safe Use of Lasers, section 7.3.
U.S. Government’s Code of Federal Regulations: 29 CFR 1910,
Subpart Z.
Threshold Limit Values (TLV’s) published by the American Confer-
ence of Governmental Industrial Hygienists (ACGIH).
It may be necessary to consult with local governmental agencies
regarding restrictions on the venting of processing vapors.
Warning

Synrad Series 48Series 48
Series 48Series 48
Series 48 operator’s manual
Hazard information
Series 48 lasers should be installed and operated in manufacturing or laboratory facilities by trained
personnel only. Due to the considerable risks and hazards associated with the installation and operational
use of any equipment incorporating a laser, the operator must follow product warning labels and instruc-
tions to the user regarding laser safety.
Exercise safe operating practices per ANSI Z136.1-2000 at all times when actively lasing.
To prevent exposure to direct or scattered laser radiation, follow all safety precautions specified through-
out this manual.
Do not place your body or any combustible object in the path of the laser beam.
Always wear safety glasses or protective goggles with side shields to reduce the risk of damage to the eyes
when operating the laser.
A CO2laser is an intense heat source and will ignite most non-metallic materials under the proper
conditions. Never operate the laser in the presence of flammable or explosive materials, gases, liquids, or
vapors.
The use of controls or adjustments or performance of procedures other than those specified herein may
result in exposure to hazardous invisible laser radiation, damage to, or malfunction of the laser. Severe
burns will result from exposure to the laser beam.
Safe operation of the laser requires the use of an external beam block to safely block the beam from
traveling beyond the desired work area. Use a water-cooled beam dump or power meter, or similar non-
scattering, noncombustible material as the beam block. Never use organic material or metals as the beam
blocker; organic materials, in general, are apt to combust or melt and metals act as specular reflectors
which may create a serious hazard outside the immediate work area.
Other hazards
The following hazards would be typical for this product family when incorporated for intended use: (A)
risk of injury when lifting or moving the unit; (B) risk of exposure to hazardous laser energy through
unauthorized removal of access panels, doors, or protective barriers; (C) risk of exposure to hazardous
laser energy and injury due to failure of personnel to use proper eye protection and/or failure to adhere to
applicable laser safety procedures; (D) risk of exposure to hazardous or lethal voltages through unautho-
rized removal of covers, doors, or access panels; (E) generation of hazardous air contaminants that may be
noxious, toxic, or even fatal.
Additional laser safety information
The SYNRAD web site (http://www.synrad.com/LaserFacts/lasersafety.html) contains an online laser
safety handbook that provides information on (1) Laser Safety Standards for OEM’s/System Integrators
including product classification, product housing, product features, and other CDRH requirements; (2)
Laser Safety Standards for End Users including Class I installations, Class IV installations, laser hazards,
ANSI Standard, U.S. State requirements, and OSHA; (3) References and Sources including CDRH,
ANSI/OSHA; and (4) Assistance with Requirements.
In addition, the Occupational Safety and Health Administration (OSHA) provides an online Technical
Manual (located at http://www.osha-slc.gov/dts/osta/otm/otm_iii/otm_iii_6.html). Section III, Chapter 6
and Appendix III are good resources for laser safety information.
Another excellent laser safety resource is the Laser Institute of America (LIA). Their comprehensive web
site is located at http://www.laserinstitute.org.

Agency compliance
The Agency compliance section includes subsections:
■Center for Devices and Radiological Health (CDRH) requirements
■Federal Communications Commission (FCC) requirements
■European Union (EU) requirements
SYNRAD lasers are designed, tested, and certified to comply with certain United States (U.S.) and
European Union (EU) regulations. These regulations impose product performance requirements related
to electromagnetic compatibility (EMC) and product safety characteristics for industrial, scientific, and
medical (ISM) equipment. The specific provisions to which systems containing Series 48 lasers must
comply are identified and described in the following paragraphs. Note that compliance to CDRH, FCC,
and EU requirements depends in part on the laser version selected – Keyswitch or OEM.
In the U.S., laser safety requirements are governed by the Center for Devices and Radiological Health
(CDRH) under the auspices of the U.S. Food and Drug Administration (FDA) while radiated emission
standards fall under the jurisdiction of the U.S. Federal Communications Commission (FCC). Outside
the U.S., laser safety and emissions are governed by European Union (EU) Directives and Standards.
In the matter of CE-compliant laser products, SYNRAD, Inc. assumes no responsibility for the compli-
ance of the system into which the product is integrated, other than to supply and/or recommend laser
components that are CE marked for compliance with applicable European Union Directives.
Because OEM laser products are intended for incorporation as components in a laser processing system,
they do not meet all of the Standards for complete laser processing systems as specified by 21 CFR, Part
1040 or EN 60825-1. SYNRAD, Inc. assumes no responsibility for the compliance of the system into
which OEM laser products are integrated.
Center for Devices and Radiological
Health (CDRH) requirements
Keyswitch models
Series 48 Keyswitch model lasers comply with requirements for Class IV laser products imposed by the
Radiation Control for Health and Safety Act of 1968. Under this Act, the U.S. Food and Drug Adminis-
tration (FDA) issued a performance standard in the Code of Federal Regulations (CFR) for laser products.
This performance standard, (21 CFR, Subchapter J, Part 1040.10) was developed to protect public health
and safety by imposing requirements upon manufacturers of laser products to provide an indication of the
presence of laser radiation, to provide the user with certain means to control radiation, and to assure that
all personnel are adequately warned of potential hazards through the use of product labels and instruc-
tions.
Product features incorporated into the design of Series 48 lasers to comply with CDRH requirements are
integrated as panel controls or indicators, internal circuit elements, or input/output signal interfaces.
Specifically, these features include a keyswitch (Keyswitch versions), lase and laser ready indicators,
remote interlock for power on/off, a laser aperture shutter switch, and a five-second delay between power
on and lasing. Incorporation of certain features is dependent on the laser version (Keyswitch or OEM).
Table 1, Class IV safety features, indicates which features are available on Series 48 lasers, the type and
description of the feature, and if the feature is required by CDRH regulations.

OEM models
Series 48 OEM lasers are OEM products intended for incorporation as components in laser processing
systems. As supplied by SYNRAD, these lasers do not meet the requirements of 21 CFR, Subchapter J
without additional safeguards. In the U.S., the Buyer of these OEM laser components is solely responsible
for the assurance that the laser processing system sold to an end user complies with all laser safety
requirements before the actual sale of the system. Under CDRH regulations, the Buyer must submit a
report to the CDRH prior to shipping the system. In jurisdictions outside the U.S., it is the sole responsi-
bility of the Buyer of these OEM components to ensure that they meet all applicable local laser safety
requirements. In cases where the Buyer is also the end-user of the OEM laser product, the Buyer/end-user
must integrate the laser so that it complies with all applicable laser safety standards as set forth above.
Federal Communications Commission
(FCC) requirements
The United States Communication Act of 1934 vested the Federal Communications Commission (FCC)
with the authority to regulate equipment that emits electromagnetic radiation in the radio frequency
spectrum. The purpose of the Communication Act was to prevent harmful electromagnetic interference
(EMI) from affecting authorized radio communication services. The FCC regulations that govern
industrial, scientific, and medical (ISM) equipment are fully described in 47 CFR, Part 18, Subpart C.
SYNRAD’s Series 48 lasers have been tested and found to comply by demonstrating performance
characteristics that have met or exceeded the requirements of 47 CFR, Part 18, Radiated and Conducted
Emissions.
FCC information to the user
NOTE: The following FCC information to the user is provided to comply with the requirements of 47
CFR, Part 18, Section 213.
Interference Potential
In our testing, SYNRAD, Inc. has not discovered any significant electrical interference traceable to
Series 48 lasers.
System Maintenance
Ensure that all exterior covers are properly fastened in position.
Measures to Correct Interference
If you suspect that your Series 48 laser interferes with other equipment, take the following steps to
minimize this interference:
1 Use shielded cables to and from the equipment that is experiencing interference problems.
2 Ensure that the Series 48 laser is properly grounded to the same electrical potential as the equip-
ment or system it is connected to.
3 Install bisected ferrite on the laser’s DC power cables; locate them as close as possible to the laser
housing.

FCC caution to the user
The Federal Communications Commission warns the user that changes or modifications of the unit not
expressly approved by the party responsible for compliance could void the user’s authority to operate the
equipment.
European Union (EU) requirements
Laser safety standards
Under the Low Voltage Directive, 73/23/EEC, the European Norm (EN) document EN 60825-1 was
developed to protect persons from laser radiation by imposing requirements upon manufacturers of laser
products to provide an indication of laser radiation; to classify laser products according to the degree of
hazard; to require both user and manufacturer to establish procedures so that proper precautions are
adopted; to ensure adequate warning of the hazards associated with accessible radiation through signs,
labels, and instructions; to improve control of laser radiation through protective features; and to provide
safe usage of laser products by specifying user control measures.
Keyswitch models
Series 48 Keyswitch models are designed to comply with the requirements imposed by EN 60825-1
for Class IV laser products. Table 1, Class IV safety features, summarizes Series 48 product features,
indicating the type and description of features and whether those features are required by European
Union regulations.
OEM models
Series 48 OEM lasers are OEM products intended for incorporation as components in laser process-
ing systems. As supplied by SYNRAD, these lasers do not meet the requirements of EN 60825-1
without additional safeguards. European Union Directives state that “OEM laser products which
are sold to other manufacturers for use as components of any system for subsequent sale are not
subject to this Standard, since the final product will itself be subject to the Standard.” This means
that Buyers of OEM laser components are solely responsible for the assurance that the laser
processing system sold to an end-user complies with all laser safety requirements before the actual
sale of the system. Note that when an OEM laser component is incorporated into another device or
system, the entire machinery installation may be required to conform to EN 60204/292, Safety of
Machinery; the Machinery Directive EN 89/392/EEC; and/or any other applicable Standards. In
cases where the Buyer is also the end-user of the OEM laser product, the Buyer/end-user must
integrate the laser so that it complies with all applicable laser safety standards as set forth above.
