LZ30 User Manual Section 3: SAFETY
Ver. 1.05 (02/2015) P/N 2302324 Page 8
Section 3: SAFETY
The LZ30 is an integrated, electrical, optical, software, and mechanical device. It is
designed with safety and effectiveness in mind. User knowledge of the potential optical
and electrical hazards is important for the safe operation of this device.
Precautions
Failure to comply with precautions and warnings described herein may lead to injury
due to exposure to dangerous optical laser radiation sources. Please review carefully
and comply with all safety instructions provided for this device.
Laser Safety
LZ30 is a Class 3B laser device. The FDA has determined that a Class 3B laser is
hazardous if the eye is exposed directly, but diffuse reflections such as those from
paper or other matte surfaces are not harmful. Protective eyewear is typically required
where direct viewing of a class 3B laser beam may occur.
Safety Instructions
Follow these safety instructions before and during treatments:
All operatory entrances must be marked with an appropriate laser warning sign
included with shipment.
Do not operate in the presence of explosive or flammable materials. Flammable
anesthetics or oxidizing gases such as nitrous oxide (N2O) and oxygen should be
avoided. Solvents of adhesives and flammable solutions used for cleaning and
disinfecting should be allowed to evaporate before laser is used. Attention should
also be drawn to the danger of ignition of endogenous gases.
All persons present in the operatory must wear protective laser eyewear.
Periodically inspect laser eye wear for pitting and cracking.
!
NOTE: For replacement or additional protective laser eyewear, please contact your
authorized dealer.
!
WARNING: Do not look directly into the beam or at specular reflections.

LZ30 User Manual Section 3: SAFETY
Ver. 1.05 (02/2015) P/N 2302324 Page 9
!
DANGER: Never direct or point the beam at anyone’s eyes or at reflective
surfaces.
!
DANGER: Do not aim the laser at metallic or reflective surfaces, such as surgical
instruments. If aimed directly at these surfaces, the laser beam will reflect and
create a potential hazard.
Always power off the device before exchanging apertures.
Switch the unit off before leaving the unit unattended.
!
CAUTION: Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure.
!
CAUTION: Do not use this unit if you suspect it of functioning improperly or other
than described herein.
!
CAUTION: This unit has been designed and tested to meet the requirements of
electromagnetic, electrostatic, and radio frequency interference standards.
However, the possibility of electromagnetic or other interference may still exist.
!

LZ30 User Manual Section 4: CLINICAL APPLICATIONS
Ver. 1.05 (02/2015) P/N 2302324 Page 12
Section 4: CLINICAL APPLICATIONS
Indications for Use
The LZ30 is intended to emit energy in the visible and near infrared spectrum to provide
topical heating for the purpose of elevating tissue temperature for a temporary relief of
minor muscle and joint pain and stiffness, minor arthritis pain, or muscle spasm; the
temporary increase in local blood circulation; and the temporary relaxation of muscles.
Clinical Instructions
The LZ30 is a 637nm and 808nm diode laser system designed to provide laser energy
to tissue for the purpose of elevating the temperature and providing temporary relief of
minor pain.
Pain affected sites, muscles and/or joints, have to be exposed to an adequate level of
therapeutic energy for effective therapeutic effects.
The LZ30 may be applied directly to the skin. Most patients will feel a very mild warmth.
In rare cases of discomfort, increase the distance between the device and the skin
and/or reduce the power.
Factors that Affect Treatment
Color of skin (Fitzpatrick Scale –see below).
Age of lesion.
Depth of lesion.
Sensitivity of patient.
Type of tissue.
Condition of treated area: Areas with poor circulation are more likely to get hot than
areas that have good blood supply.
Medications that increase sensitivity to light.
Recommended Clinical Settings:
Some patients may require more than one laser application or a series of treatments
before significant improvement is reported. Repeat this therapy as necessary and
monitor progress of the patient’s condition throughout the treatment.
Fitzpatrick Scale
Type I Pale white; blond or red hair; blue eyes; freckles —Always burns, never tans

LZ30 User Manual Section 4: CLINICAL APPLICATIONS
Ver. 1.05 (02/2015) P/N 2302324 Page 13
Type II White; fair; blond or red hair; blue, green or hazel eyes —Usually burns,
tans minimally
Type III Cream white; fair with any hair or eye color; quite common —Sometimes
mild burn, tans uniformly
Type IV Moderate brown; typical Mediterranean skin tone —Rarely burns, always
tans well
Type V Dark brown; Middle Eastern skin types —Very rarely burns, tans very easily
Type VI Deeply pigmented dark brown to black —Never burns, tans very easily
Universal Aperture at 30 mm spot size (against the skin):
TYPE I, VI: .........Do not exceed 60J at each site.
TYPE II:..............Do not exceed 120J at each site.
TYPE III, IV, V:...No special restrictions. Follow general recommendations for
treatment (above).
Universal Aperture
The Universal Aperture is installed on the LZ30 when you receive it. This aperture is
designed for a wide beam divergence and hence can be applied directly against the
patient. This is the recommended use, since it also increases patient and operator
safety by eliminating stray radiation.
