Constellation

Vision System
SECTION THREE
OPERATING INSTRUCTIONS
INTRODUCTION
This section details the recommended setup and operation for the Constellation
®
Vision
System. These procedures may be modified to conform to hospital requirements and practices
as you become experienced in using the system. The operational checks however, that are
performed at various points in the setup procedure to verify instrument operation, must be
performed exactly as indicated.
The procedures are divided into two columns and presume a surgical team of three people:
Surgeon and
Scrub Nurse in the sterile field, and a Circulating Nurse in the non-sterile field.
In the left column a directive is given; in the right column the responsible team member is
identified.
Any problems pertaining to setup and check-out procedures should first be directed to the
Troubleshooting section of this manual. If questions still exist, contact the Alcon Technical
Services Department or your local Alcon representative.
POWER UP SEQUENCE
When the
power switch is turned on, and the standby switch is pressed, the
Constellation
®
Vision System logo screen appears while the system performs its
self-test diagnostics. The system is capable of detecting and reporting a wide range of
fault and error conditions. Many of these are checked during the power up procedure.
If a fault is detected during power up, the user is informed and the instrument
becomes non-operational until the failure/problem is corrected. Upon successful
completion of the self-tests, the system enters the setup screen.
