U SER MANUAL > S AFETY CONSIDERATION
Nevertheless, special precautions need to be observed:
The use of accessories and cable other than those specified, with the exception of accessories and cables
sold of the slit lamp microscope as replacement parts for internal components, may result in increased
EMISSIONS or decreased IMMUNITY or decreased LIFESPAN of the slit lamp microscope.
The slit lamp microscope should not be used adjacent to or stacked with other equipment. In case
adjacent or stacked use is necessary, The slit lamp microscope should be observed to verify normal
operation in the configuration in which it will be used.
The length of cables or cords must be greater than 1.8 meters.
