must be performed exactly as indicated.

WARNING!

Noncompliance with the instructions contained in this manual may result in

operator injury.

The following procedures (Initial Setup, System Connections, System Power Up, and

Operation) cover preparation for laser treatment involving Slit Lamp, Endoprobe/

Aspirating Endoprobe/Illuminated Endoprobes, or LIO usage.

Any questions pertaining to setup and checkout procedures should be directed to your

Alcon Technical Services representative.

1 INITIAL SETUP

WARNING!

To avoid potential secondary reflections, a qualified laser safety officer should

approve the room used to treat the patient.

1.1 Position the instrument for surgeon’s comfort and preference. Refer to Section

1.2 Verify that no combustible materials are adjacent to the laser and its delivery

systems.

2 SYSTEM CONNECTIONS

2.1 Connect footswitch to Footswitch connector.

2.2 Connect Remote Interlock to REMOTE Interlock connection.

2.3 Plug in the power cord to the power cord socket and to a properly grounded

main power outlet (220-240 VAC, 10A minimum; or 100-120 VAC, 15A

minimum).

2.4 Ensure all Doctor/Observer protection ﬁ lters are installed in the optical path of

the slit lamp or microscope, and connected to the Doctor Protection Filter ports

WARNINGS! The Slit Lamp must be equipped with a special Alcon Slit Lamp adaptation. This adaptation is available for many of the existing Slit Lamps. (Reference section six for list of adaptations to be used with existing slit lamps.) If peripherals are not correctly connected and confirmed by the operator, the operator and patient will be exposed to hazardous radiation. Refer to Section Six for instructions on installing the Doctor Protection Filter.

WARNINGS! Performing procedures other than those specified herein may result in hazardous laser radiation exposure. Everyone present in the treatment room must wear protective eyewear O.D. 4 or above at 532 nm when the system is in standby as well as during treatment. Possible explosion hazard if used in the presence of flammable anesthetics or other gas mixtures.
