2.2 Warnings and Precautions
The following warnings and precautions apply to the Multi-Wavelength Pattern
Scanning System - LightLas 532 / 670 and should be observed by all users at all time:
DO NOT look directly into or at the laser beam or at specular laser reflections
since direct and reflected laser light from the laser aperture can cause
permanent eye injury.
DO NOT operate the laser unless observers are using the correct protective
eyewear. The protective eyewear must have an optical density of OD4 or
more at 532 nanometers wavelength. This information must be present on
the eyewear.
DO NOT use objects that can readily reflect light in the vicinity of the laser
beam to avoid reflecting the beam in a hazardous manner.
DO NOT fire the Laser directly onto flammable agents or gasses as the
focused laser beam may cause ignition. There is no AP/ APG protection.
DO NOT try to service or repair the laser other than what is included in this
manual. Service should only be performed by an authorized and trained
agent of the manufacturer.
DO NOT fire the laser on a patient without first checking the operation of
the laser and verifying the optical alignment of the treatment Laser beam.
ALWAYS use the lowest power settings possible when treating a patient
with the laser and start the treatment with minimum level of power.
ALWAYS set the correct spot size and/or use the most appropriate one for
the power setting and type of procedure that is to be performed.
DO NOT put the laser into ‘TREAT’mode until ready to operate on the
patient.
DO NOT inhale any laser plume generated by the Laser during surgery.
Personnel should take an extreme measured precaution, such as wearing
surgical masks or use plume evacuation systems when a treatment is
undergoing. Caution - Laser plume may contain viable tissue particulates.
ALWAYS take particular care of the optical fibers that connect the Laser
Delivery Units to the Console to make sure they do not get damaged.

Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 - Service Manual Page 13 Rev. No 01
Additional clinical warnings may be found in Section 6.1.4 of this Manual.
ALWAYS try to let the laser have its own or dedicated power outlet.
Additional items may be plugged in a Multiple Portable Socket Outlet, which
may be plugged into an additional outlet.
DO NOT use the Laser Console if the ambient temperature is outside the
range of 20 to 35°C. This temperature range is the rated operating
temperature limits where the Laser system can be guaranteed to operate
without any interruptions to normal use. Outside this range of temperature
it is possible that the Laser will generate an error condition where the word
“hold” is displayed and the system goes to Standby until the internal
temperature returns to within normal limits then the Laser can be used again
but the error condition may reoccur unless the rated temperature comes
within limits.
2.3 Optical Hazards
Guidance for the safe use of Lasers and Laser systems is found in the standard
IEC60825-1, the USA 21CFR 1040.10, 1040.11 and ANSI Z136.1 - 1986.
During normal operation of the Multi-Wavelength Pattern Scanning System - LightLas
532 / 670 the operator is protected from Laser hazards by built in optical absorption
Safety Filters. All other personnel in the area should wear protective eyewear to
eliminate the risk of eye injury occurring.
The optical density (OD) of eye protection must be greater than or equal to 4 and the
wavelength 532nm and 670nm range are also specified on it. It is shown in the
following format:
OD4+ @ 532nm / 670nm
Otherwise, the safety glasses are NOT suitable for this purpose of eye protection.
Safety Glasses are required to have the CE mark applied if used in the EU.
The Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 uses a Class II
Laser Diode Aiming beam. Its wavelength range from 635 to 650 nanometers (nm)
and the maximum power output is set at the factory to be less than 1mW delivered to
the patients cornea. However it is always recommended to use the lowest aiming
beam intensity during treatments.
The Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 Photocoagulator
Laser has been classified as a Class 4 and its classification specified accordingly to the
above quoted standards. This classification is also based on the Accessible Emission
Limits (AEL) as calculated according to the standards.

Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 - Service Manual Page 14 Rev. No 01
2.3.1 Nominal Ocular Hazard Distance (NOHD)
The Nominal Ocular Hazard Distance (NOHD) is the distance between the equipment
and a person’s eye for which the optical power, from the equipment, entering the
dilated pupil of the person will be less than or equal to the Maximum Permissible
Exposure (MPE) as specified in the standards (i.e. less than a Class 1 Laser Output).
The calculated NOHD for the Multi-Wavelength Pattern Scanning System - LightLas
532 / 670 with different Laser Delivery Units is:
5 meters at maximum power settings for the Endoprobes
18 meters at maximum power settings and 1000m spot size for Slit lamp
Delivery Units
20 meters at maximum power settings for LIO
Therefore when the laser is in operation, all persons that are closer than these
distances to the equipment should be wearing eye protection.
Patients, where possible, should have the untreated eye covered or protected from
laser reflections.

Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 - Service Manual Page 15 Rev. No 01
2.3.2 Avoid Exposure to Laser beams
Reassembly or maintenance of the laser system should only be performed by
authorized and trained personnel. The external housing of the laser system should
never be removed otherwise you or standby observers could be exposed to
dangerous levels of laser radiation and potentially lethal electrical voltages.
Eye safety filters are designed to protect physician’s eyes from back scattered laser
beams must always be used. They are integrated into the Slit lamp and LIO Delivery
Units. When using the endoprobes a separate filter that attaches to the operating
microscope must be used.
For other personnel that may be exposed to reflections or backscatter they must
wear safety glasses or goggles. In any case NEVER look directly at the treatment
laser beam as severe eye injury is likely. This means avoid looking into the aperture of
any of the laser delivery units or the console.
2.4 Electrical Hazards
The Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 Photocoagulator
laser has been designed to apply the International Standards for Medical Equipment.
The laser system is designed to operate with three terminal prongs AC voltage where
the third prong pin is the earth-grounded prong.
Warning: It is not safe to operate the Multi-Wavelength Pattern Scanning System -
LightLas 532 / 670 photocoagulator laser without an earth-grounded receptacle.
There is possible risk of electric shock.
No cover or housing need to be removed by the operator or user. Only the
authorized and trained service or agent can remove the cover or housing assembly
since there is possible of exposing laser radiation and high current or voltages.

It is strongly recommended that the manufacturer or its authorized agent install the
Multi-Wavelength Pattern Scanning System - LightLas 532 / 670 at the operator site to
ensure that the system is operating correctly, aligned and calibrated according to
specification. After this initial installation it is the operator’s responsibility to ensure
the laser system is operating correctly whenever the laser is moved or relocated.
The following procedures should be followed in order to successfully install the laser
system. The checklist and report form should be completed and a copy sent to the
manufacturer. In the event that the report is not sent to the manufacturer then the
manufacturer reserves the right to decline any warranty claims that may be
forthcoming.
The installer should also retain a copy and the customer may keep a copy too.
All precautions care must be taken when installing the Multi-Wavelength Pattern
Scanning System - LightLas 532 / 670 to ensure that you or others are not exposed to
any hazardous laser radiation. Always wear laser safety glasses suitable for the
532nm wavelength to protect your eyes.
Requirements
1. 100-230 Volts, 50 or 60Hz AC mains power supply with an earth connection.
This is a single-phase outlet capable of delivering up to 400 Watts.
2. A motorized stand that the Table provided with the Slit lamp can be fitted
to is required if one was not purchased with the Laser system. Ensure the
Table is fitted securely to the Stand using the supplied screws.
3. A mains power cable is supplied but the connector may not suit the outlet
available so it is advisable to have a spare locally compatible cable available.
The Cable assembly must be CE approved for EU Countries.
4. A suitable room to place the Laser System in that provides for a safe
working environment is required. As with other ophthalmic equipment a
dimly lit room is preferred.
5. The Laser System has the facility to connect a remote door interlock to the
Laser treatment room. If this option is required then the customer must
organize this with an electrician and the manufacturer or authorized agent
can provide instructions on how to connect to the Laser System. The Laser
System is provided with a Bypass plug in the event that this option is not
installed. This plug is referred to as the “Interlock Key” and must be
inserted into the back of the console, in order for the system to operate.
