GENERAL DESCRIPTION
FRONT PANEL COMPONENTS
The front panel of the Accurus® system is a multifunctional user interface that allows user control of most system functions. The descriptions of the front panel components are coded to match the illustration in Figure 2-2, which is a helpful reference while learning the system's functions.
1. Global Functions
The global functions area of the system is located at the top-left portion of the front panel. Global functions can be used any time and in any mode. Its three major components are described below.
1A. Global Function Selection Keys
These five keys, located within the color LCD display, are used to select the following functions (from top to bottom):
• Infusion/Irrigation pressure
• Fluid/Air Exchange pressure
• Diathermy power
• Two light sources for fiber optic illumination 1B. Global Function Up/Down Adjustment Buttons
The up/down adjustment buttons are located to the left of the global function selection keys, and are used to adjust their associated global function values.
These buttons can be pressed quickly to change values one digit at a time, or pressed and held to rapidly change the values.
1C. Global Function LED Displays
The five LED displays, located to the left of the adjustment buttons, display current global function settings when a global function is on, or while a setting is being adjusted.
The Diathermy global function is always enabled for footswitch activation, and its LED readout is always lit; its icon key illuminates bright blue when activated.
2. Color LCD Display and Touch Screen
The color LCD display and touch screen is located in the upper-right section of the front control panel. This graphic user interface displays icons, keys, and readouts appropriate to the mode of operation and system status. The operator presses the icons and keys on the screen to interact with the system.
3. Fluid Cassette with Aspiration and Irrigation Ports
Three types of cassettes are used with the Accurus® system, each with its own assortment of male/female ports designed for connection of irrigation/infusion and aspiration/extrusion tubing. For posterior there are two aspiration ports, for anterior there are two irrigation ports and one aspiration port, and for combined anterior/
posterior there are three irrigation/infusion ports and two aspiration/extrusion ports.
Cassettes used with the Accurus® system convert vacuum generated by the console into aspiration/extrusion, and collect the aspirated fluid into a small, rigid, collection chamber. The collection chamber is continuously drained into a sealed drain bag, hanging from the front of the cassette. The cassette's design allows it to be removed from the console without spilling the collected fluids.
Figure 2-2. THE ACCURUS® FRONT PANEL (Depicted: 300VS, 400VS, 600DS, 800CS) - The front panel consists of five three-character, seven-segment LED displays; five sets of membrane up/down arrow keys;
a color LCD with touchscreen; a cassette eject button; two cassette port LED's; up to twelve handpiece/probe connectors; an illuminator drawer with two illuminator ports; and a power On/
Off standby switch. Three cassettes are available for use with the Accurus® system; the anterior cassette is shown in this illustration. NOTE: Item 7 (Illuminator Drawer) is removed in the 200PS model.

4. Cassette Port LEDs
One LED is located on each side of the cassette. During surgery, and while priming, the LEDs illuminate to indicate which cassette port is active.
5. Eject Button
Pressing the Eject button, located to the left of the cassette, releases the latch that secures the cassette within its receptacle, allowing removal of the cassette.
This button is active when the system is supplied with air pressure, but is invalid when vacuum is activated or system power is turned OFF. The cassette will not load or unload if MPC scissors are activated.
6. Pneumatic and Electrical Connectors
The Accurus® console contains two vertical columns of connectors, with six connectors in each, for surgical probes and handpieces. The left column is for pneumatic probes, and the right column is for electrical handpieces. Figure 2-3 identifies each connector.
WARNING!
Connect only Alcon supplied consumables to console/cassette connectors. Do not connect consumables to patient intravenous connections.
Connector LED's
There are twelve LED's located next to their respective connectors on the front of the console. These LED's have dual functions:
• During surgery setup, when the operator selects a probe, handpiece or accessory, the corresponding LED illuminates to guide the operator to the correct connector.
• During surgery these LED's are used to indicate which connectors are active.

7. Illuminator Drawer
The illuminator drawer contains bulbs, mirrors, and lenses to direct high intensity light to fiber optic illumination probes. Pushing the illuminator release button on the rear panel ejects the drawer from its slot (see Figure 2-4). When the illuminator drawer is ejected, both illuminators turn off, allowing the user to replace burnt bulbs. The bulbs only illuminate when the drawer is fully inserted into its slot.
• Illuminator Receptacles - Illuminator receptacles accept Intralux connectors.
• Illuminator Adaptors - Tethered ACMI adaptors are used to adapt Alcon illumination probes to the illuminator receptacles.
8. Standby Switch
This switch is used to turn internal DC power ON and OFF, usually between surgeries. Use the Main Power Switch (see Figure 2-4) to fully shut down the system for extended periods of time (overnight) to reduce power consumption and/or eliminate unnecessary operation of the Accurus® Power Supply.
9. Speaker
Voice confirmations and tones are emitted from the speaker, hidden behind the front panel grill, to audibly alert operator to system operating status (see Table 2-1).
DESCRIPTION
Table 2-1. VOICES/TONES AND THEIR DESCRIPTIONS - Voice and tone volumes, set at the factory, can be adjusted in any screen where the Options key is available (in the Options/Volume screen, or Options/Memory/Common/Sound screen). The Fault, Error, Diathermy, and Invalid Key tones can not be lowered below a minimum value; all other adjustable tones can be turned completely off. If the Voice volume level is set to zero, then tones are used for infusion changes and when turning the vitreous cutter and fragmentation power on/off.
