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.
