Emission Indicators

3.5.1.
The Emission Indicator Ring on the Empower IQ™ will change colors during emission based on
the dosing technique. During ideal dosing, the LED will remain green. When the hand piece is
stopped or moved too slow during emission, the LED will turn red. When the hand piece is
moved too fast during emission, the LED will turn yellow. When Vibration feedback is turned on,
the hand piece will vibrate when in the red (too slow) or yellow (too fast) condition (Figure 14).
The handpiece will not vibrate in any condition when Vibration Feedback is Off. When Visual
Feedback is Off, the indicator ring will remain white during emission.
3.5.2.

Quick Disconnect Treatment Heads

Recommendation: If the Empower IQ is not performing as described above, check the Empower IQ settings in Setup and reconnect
the Empower IQ, if needed – see Section 2.3 for more detailed steps.
To attach a treatment head, locate the metal insert on the inside of the opening. Line up the slot within the metal insert with the bearing on
the mating end of the hand piece (Figure 15). The hand piece and treatment heads are keyed so they will only fit and attach in this orientation.
Once they are lined up, push the attachment onto the end of the hand piece so it is fully seated. Then while holding the hand piece, rotate
the attachment clockwise until it clicks. This indicates the attachment is fully engaged, locked in, and ready for use. (Figure 16)

Treatment Head Attachments

3.5.3.
To confirm successful connection, the corresponding treatment head icon on the Operation screen will be highlighted. The icon background
color will be based on whether it is recommended or not based on the current Protocol or treatment settings.
Note: Not all treatment head attachments are available with each laser system. The device guides the user on the appropriate
treatment head to use and will provide error messages when invalid attachments are used.
Beam divergence and the Nominal Ocular Hazard Distance (NOHD) for each of the treatment heads are listed in the above table. NOHD is
defined in ANSI Z136.3 as "the distance along the axis of the unobstructed beam from the laser to the human eye beyond which the irradiance
or radiant exposure during normal operation is not expected to exceed the appropriate Maximum Permissible Exposure (MPE)." At distances
greater than the NOHD, the beam intensity becomes lower than the MPE. Worst case for the laser systems is with the Large Massage Ball
at 8.0 m.
