Empower™ Delivery System
Caution:
Do not bend the optical fiber too sharply: the minimum permissible bending radius is 40 mm. Mishandling of the fiber may lead
to damage to the fiber or delivery system and/or harm to the patient or laser operator.
Warning:
•
If any part of the Empower Delivery System overheats or produces smoke, immediately power off the Laser System, discontinue
operation, and contact Customer Care for assistance.
•
The use of accessories and/or optical fiber cables not specified for use with this Laser System may result in unsafe emissions or
damage to the Laser System.
The Empower Delivery System is composed of a double-sheathed optic fiber and a hand piece with interchangeable treatment
heads. The laser emission is controlled with a finger switch on the hand piece. During Emission, the LED indicator will illuminate.
). The functionality of the finger switch is influenced by the “Override” setting in Setup. When the operator is
administering a treatment with Override
Off
, the finger switch must be held down continuously to enable emission. When Override
is
On
, the finger switch acts as an ON/OFF switch allowing the operator to press once and release to enable continuous emission.
Warning:
The
Override On
setting for the finger switch should only be used by a qualified laser technician.
To end emission, the operator will then press and release again, which will return the laser to
Ready
mode. The laser system will remain in
Ready
mode until the operator resumes the treatment or selects
Standby
on the touchscreen
to return to
Standby
mode.
Warning:
•
DO NOT press the finger switch without first verifying the safe orientation and proper positioning
of the distal end of the optical fiber and hand piece. Ensure compliance with all safety precautions.
•
DO NOT
operate the laser system without a treatment head (
Figure 16
). This can cause serious
injury.
•
DO NOT
operate the laser system with an improperly attached or loose-fitting treatment head
(
Figure 17
). This can cause serious injury.
3.5.1. Quick Disconnect Treatment Heads
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 18
). 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. (
3.5.2. Treatment Head Attachments
Beam divergence and the Nominal Ocular Hazard Distance (NOHD) for each of the treatment heads are listed in the below 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.

Recommendation:
As the aiming beam passes down the same delivery system as the working beam, it provides a good means of checking
the integrity of the delivery system. If the aiming beam is not present at the distal end of the delivery system, its intensity is reduced or it looks
diffused, this is a possible indication of a damaged or malfunctioning delivery system.
