Section 1: INTRODUCTION
The LZ30™and LZ30-X are 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.
The LZ30 and LZ30-X are identical in every respect except that the LZ30-X has higher
power output capability on the red lasers. See Section 10: (SPECIFICATIONS) for
more information. From this point forward, all references to the LZ30 apply equally to
the LZ30-X, except where noted.
The LZ30 represents the very latest in laser technology, providing high laser power, rich
features and versatility in a small, ergonomic package. The LZ30 delivers infrared laser
radiation in the visible and invisible spectrum.
The LZ30 laser is indicated for use by a licensed healthcare professional, or by order of
a licensed healthcare professional. The use of this device requires proper clinical and
technical training. The manual provides labeling instructions for the user and all other
office personnel to review and apply during use of this device.
!
FOR USE IN CANADA: This device must be installed and operated according to
the guidelines of CAN/CSA-Z386-08 “Laser Safety in a Health Care Facility.”

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.
!
DANGER: There are no user serviceable parts inside the LZ30. Do not attempt to
open the unit housing at any time. Contact Avant if you believe that your device is
not functioning correctly.
Safety Features
Key Access
As required by federal law, the LZ30 has a password system that prevents unauthorized
operation of the device. You will be prompted to enter a password each time you power
up the device. The default password is CLICK-RIGHT four times (“”), then
CLICK to enter. See “Button Operation” for information on how to operate the joystick.

LZ30 User Manual Section 3: SAFETY
Ver. 1.05 (02/2015) P/N 2302324 Page 10
!
NOTE: Ending a treatment does not reset the password. Always turn off the
device only when system is not in use.
!
NOTE: The LZ30 will automatically turn off after 30 minutes of inactivity.
!
CAUTION: You must configure your own password after receiving the device to a
value other than the default, and one that is difficult to guess. Longer passwords
afford greater safety.
To set the password, go to Settings\Password. You will first have to enter the old
password. When you enter the new password, note it down as you enter it. If you lose
your password, your device will become inaccessible and will need to be returned to
Avant to be reset
Automatic Power Control
Each of the laser diodes in the LZ30 has an integrated chip that measures optical power
output. This provides very accurate regulation of power output and eliminates variations
in output power that would otherwise occur due to age, wear and temperature.
System Monitor
The system monitors the following internal parameters and will take corrective action in
the event of detecting an abnormal condition.
System
Parameter
Relevance
Alarm Response
Startup
Diagnostics
Performs detailed diagnostic checks
on each system component at
startup. These thorough tests are
only run at startup because such
tests would otherwise interfere with
normal operation.
Report error to operator.
Diode Current
Ensures that laser diodes are
operating within their specified
characteristics.
Switch off all diodes.
Terminate treatment program.
Report error to user.
