Power: Press the "+" or "-" buttons or rotate the power dial to adjust the laser power. The selected laser power will be shown in the
•
power window in Watts as well as on the power dial. To scroll to the desired power value, maintain pressure on the dial and rotate in a
clockwise direction. The user can also press on the squares around the perimeter of the dial to jump to higher or lower powers.
Pulse Rate: Press the pulse rate "+" or "-" button to adjust the laser pulse rate. The selected laser frequency will be shown in the pulse
•
rate window. To scroll to the desired frequency value, maintain pressure on the desired button. The laser frequency can be set in CW
(continuous wave, not pulsed) or pulsed mode with frequencies of 2, 10, 20, 100, 200, 500, 1000, 2500, 5000, or 10,000 Hz. The duty
cycle in the pulsed mode is 50%.

Laser Emission

When the operator has set the treatment parameters and is ready to start the treatment, the operator should press the Standby button to proceed
to Ready mode.
The software has a 6 second delay (with 6 audible beeps) to warn the user of the transition from Standby to Ready mode. During the transition,
the Standby button changes to Ready and flashes. After 6 beeps, the laser is in Ready mode.
The purpose of Ready mode is to wait for the user to press the finger switch to start laser emission. In Ready mode, the laser will emit when the
finger switch is activated. The laser system will return to Standby mode from Ready mode if emission is not enabled within 100 seconds.
Note: Pressing the finger switch during the 6 second delay will result in an Operation Error. The user will need to depress the finger switch
prior to pressing exit, at which time the system will return to Standby.
Warning: NEVER leave this device unattended in Ready mode.
In Ready mode:
• The Ready button is active and the aiming beam emits from the hand piece.
• The selected time, power, and pulse settings are still adjustable; however, the skin color is not adjustable.
To start laser emission, press the finger switch. To stop emission, remove finger from the finger switch. The laser emission can
•
be enabled again by pressing the finger switch until the remaining time is over.
Note: If the unit has the finger switch override ON, each time the finger switch is pressed, it will act as an on/off switch.
During emission, the word "EMISSION!" will replace the Ready button on the screen and the software does not
allow the user to change any settings. In addition, the laser system will produce beeps, or a steady audible tone
according to the audio settings chosen in Setup, and the aiming beam will continue to emit. Furthermore, the LED
emission indicator on the front bezel will illuminate for the duration of the treatment.

Laser Treatment Procedure

This section contains information about the protocols and settings on this device. The following treatment recommendations are provided for
guidance only. The practitioner is the person who determines the settings and protocol to use when treating each individual patient.
4.4.1.

Pigment Considerations

This laser system will deliver a dual wavelength of 810 nm and 980 nm light which has been found to provide therapeutic relief of pain. This laser
system allows the operator to choose skin color type for the patient. Since darker pigments will absorb 810 nm wavelength more than lighter
pigments, the software will adjust the output so that it contains 100% 980 nm wavelength when the dark skin setting (Fitzpatrick V or VI) is selected.
Other circumstances when it may be appropriate to use this setting include:
• Highly pigmented areas, such as areas with a dark sun tan, or areas with a tattoo
Areas with dense hair growth, such as the nape of the neck
•
4.4.2.

Dose

The laser energy dose delivered during a treatment is measured in joules. This number is displayed on the screen during a treatment and is
calculated by multiplying the average power (in Watts) by treatment time (in seconds). Laser treatment should be applied to an area using a
scanning application.
The software protocols in the laser system are designed to deliver a dose appropriate for the treatment area and conditions input by the operator.
It is recommended that treatment information (pre-set protocol and input settings or power, energy delivered, treatment time, and treatment area)
is recorded for each treatment.
• In general, doses are delivered to the area of pain, the surrounding tissues, and along the nerve pathway for the specific area
experiencing the pain.
• Treat muscles connecting to a painful joint in addition to tendon attachments.
4.4.3.

Setting Treatment Expectations

Patients and clinicians need to understand the possibilities and limitations of the application of deep tissue laser therapy. Chronic pain may require
several treatments before a beneficial effect is achieved. Deeper tissues may require multiple treatments before significant benefits are derived.
A typical treatment regimen may consist of three treatments spaced one day apart during the first week, two treatments the following week, and
one treatment in week three. If no benefit is derived after the 6 to 10 treatments, then the patient's options need to be reviewed considering the
condition and response. Occasionally, a patient can experience a tingling sensation or soreness due to increased blood flow. In these instances,
it is recommended to wait until the soreness subsides before continuing with additional treatments.
