REAR PANEL COMPONENTS

The rear panel of the Accurus^® system contains a variety of components. The

descriptions of the rear panel components are coded to match the illustration in Figure 2-4, which is a helpful reference while learning the system's functions.

1. PC Card Slot

The PC Card Slot is used to export and import doctors memories via a Doctor Memory Card, or to install system software upgrades (if required). The memory cards used for these functions are inserted into the slot and pushed in until it is firmly in place and the eject button is pushed out. Pushing the eject button will eject the card out of the slot.

2. Illuminator Exhaust Grate (not included with 200PS system)

Warm air is expelled from the Accurus^® console through this grate. An internal fan draws air past the illuminator components, keeping them cool for longer life.

For proper cooling at least two feet of clearance must be provided at the rear of the unit to ensure unrestricted air flow.

Figure 2-4. THE ACCURUS^® REAR PANEL - The rear panel consists of a variety of components for functional use and connection of accessories. Included are a PC slot, air input and exhaust grates, an illuminator ejector button (800CS, 600DS, 400VS, 300VS only), a cassette ejector, a compressed air connector, a footswitch connector, and a power supply.

3. Illuminator Ejector Button (not included with 200PS system)

Pressing this button ejects the Illuminator drawer from the front of the console, allowing the user to change burnt illuminator bulbs. Two bulbs are provided, allowing a backup source should a bulb burn out during surgery. Upon

completion of surgery, the burnt bulb should be replaced. (See section fifteen of this manual for instructions to replace bulbs.)

NOTE: It is recommended that two good bulbs are always installed.

4A. Selectable Power Supply with Main Power Switch, Power Input Connector, Fuse Module, Equal Potentiality Lug, and Power Supply Exhaust Grate

The Main Power Switch is used 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. The Power Input Connector accepts main power input from external electrical power source. The Fuse Module contains the fuse drawer and fuses, as well as the voltage selector box. (See section fifteen of this manual for fuse replacement and voltage selection.) The Equal Potentiality Lug is for Service personnel use, and also for equipotential equipment connection.

Warm air is expelled from the Power Supply Exhaust Grate.

4B. Auto Ranging Power Supply with Main Power Switch, Power Input Connector, two Fuse Holders, Equal Potentiality Lug, and Power Supply Exhaust Vent.

The Main Power Switch is used 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. The Power Input Connector accepts main power input from external electrical power source.

(The power supply selects correct voltage automatically.) The Fuse Holders contain two fuses. (See section fifteen of this manual for fuse replacement.) The Equal Potentiality Lug is for Service personnel use, and also for equipotential equipment connection. Warm air is expelled from the Power Supply Exhaust Vent.

5. Manual Cassette Ejector

Lifting this latch releases the fluid cassette when air pressure is not available or in the event of power outage. (See sections five, nine, and thirteen of this manual for instructions to use this cassette ejector.)

6. Cool Air Input Grate

Cool, filtered air enters the Accurus^® console through this grate. The main system cooling fan is located directly behind the input filter. For proper cooling at least two feet of clearance must be provided at the rear of the unit to ensure unrestricted air flow.

7. Compressed Air Connector

An air pressure hose from a pressure source is connected here via a Schraeder connector for input of compressed air or compressed nitrogen.

8. Power I/V Pole Connector

For connecting the power I/V pole cable from its cart to the Accurus^® console.

9. Footswitch Connector

For connecting the footswitch cable to the Accurus^® console.

FOOTSWITCH

Functional operations to the Accurus^® console are accepted from a footswitch. The footswitch consists of a footpedal, left and right horizontal/vertical switches, and left and right heel switches (see Figure 2-5). Functions controlled by the footswitch are listed in tables located in sections three, seven, and eleven of this manual. Some footswitch functions are programmable in the Options/Memory/Common/Footswitch screen.

Generally, the footpedal is used to provide control of a parameter, such as vacuum, with the footpedal's angle of depression proportional to the parameter output. In some modes of operation the footpedal is used to provide on/off control of a function, with any depression resulting in a fixed output of its parameter.

Right and left switches are used to enable and disable system functions. The switches are nudged sideways (horizontal) for some functions, and pressed down (vertical) for others.

A tension adjustment knob, located on the front of the footswitch, is used to regulate the pressure needed to depress the footpedal. Additionally, the footpedal must be pressed through detents to enter into new anterior and posterior mode positions. The detent force levels are programmable in the Options/Memory/Common/Other screen for phaco.
