density. Selected protective glasses wears comfortable, vision broad, ventilation
and closed both frame and edge should have protection with the same lens, do
not use can hinder specular reflection of plane reflection lens.
2.2.3 Protective glasses can only reduce damage to the eyes, can not totally
prevent direct laser beam and reflected laser beam by glasses, mirror and
smooth metal surface. So never look at direct laser beam or reflected laser beam
even though with protective glasses.
2.2.4 Covering gauze and wearing eye patch etc. can play protective effect on
patients’ eyes.

Electrical Safety
2.3.1 The power supply connected to Laser must have a single phase three wires
power socket that meets international standards, being well earthed in
accordance with the electrical safety regulations in force, and having a
specification of 10A or higher.
2.3.2 Before running the machine, please ensure hand piece and other
components are connected with the machine well. During treatment, never
remove the components, including hand piece. After laser stops running, pay
attention to that opening the cover of the casing may cause a high voltage
electric shock.
2.4 System Device Safety
2.4.1 Water current device: when laser emits, there is high density heat in the
hand piece. So it requires constant cooling water conduction cooling. The
machine is designed that it will alarm and no laser emitting when the water
current is poor or the flow is higher, lower than the set range.
2.4.2 Water level device: when laser emits, there is high density heat in the hand
piece. So it requires constant cooling water conduction cooling. The machine is
designed that it will alarm and no laser emitting when the flow is lower, not
enough water to ensure to normal water circulation.
2.4.3 Water temperature device: When water temperature is higher than set
temperature, machine will alarm and no laser emitting. Generally speaking,
cooling system in the machine will avoid the phenomenon.
2.4.4 Emergency Button: Press the red emergency button to shut machine down
and cut power supply immediately. Pull button out to restore power.
2.4.5 The Key Switch: Use the key to turn power on or off. Remove key and keep
safe when not in use.
2.4.6 Hand piece key and pedal switch: When the machine and working system of
the machine is normal, the hand piece key and pedal switch work at the same
time, then there will be laser emitting, which is much safer.
