Warnings and Cautions
Warning! Explosion Hazard
Risk for explosion exists if the device is operated in the presence of
flammable anesthetics, or other flammable gases or liquids.
Caution!
To reduce risk of electrical shock, do not open enclosure. There are no
serviceable parts inside. Refer service to Leica, Inc. or its authorized agent
only.
Caution!
Do not expose this equipment to rain or moisture.
Note:
Canada, Grounding reliability can only be achieved when this equipment is
connected to matching receptacle marked “Hospital Only” or “Hospital
Grade”.
Europe and Australia: Must be plugged into a grounded receptacle.
Caution!
Individuals that are allergic to system materials such as the HHP sheathing,
chin rest, or other exterior sections of the system with which they come in
contact should limit skin exposure.
Caution! Optical Radiation Hazard
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
Caution! Phototoxicity
Because prolonged intense light exposure can damage the retina, the use
of the device for ocular examination should not be unnecessarily prolonged,
and the brightness setting should not exceed what is needed to provide
clear visualization of the target structures. This device should be used with
filters that eliminate UV radiation (< 400 nm) and, whenever possible, filters
that eliminate short-wavelength blue light (<420 nm).*
Caution! Phototoxicity
The retinal exposure dose for a photochemical hazard is a product of the
radiance and the exposure time. If the value of radiance were reduced in
half, twice the time would be needed to reach the maximum exposure limit.*
