FRONT PANEL DISPLAY SCREENS

The operating screens described in this section are displayed on the front panel color LCD display. The colors and their intensities are designed for easy viewing in both light and dark environments.

Power Up Screen

The power-up initialization cycle lasts approximately two minutes. After the first ten seconds of this cycle, the Power Up Screen is displayed while the system completes initialization and self-test diagnostics (see Figure 2-7). All operator inputs are locked out at this time. After self-test diagnostics the 200PS, 300VS, and 400VS systems enter either the Posterior or Anterior domain of operation.

WARNING!

During initialization the drain pump is rotated to its home position. Therefore, keep hands and fingers clear of cassette well during power-on initialization. After initialization, do not manually turn hub roller. Finger pinch and/or improper cassette installation can occur.

If a fault is detected during self-test diagnostics, a System Fault Screen is displayed and the system becomes non-operational (see Figure 3-20).

Procedure Selection Screen

The 800CS and 600DS systems contain both Posterior and Anterior functionality, so after the power-up initialization cycle one of the following can occur:

• The Procedure Selection Screen appears, allowing entry into either the Anterior, Posterior, or the 800CS Combined domain (see Figure 2-8). The Procedure Selection Screen also appears when the Exit key is pressed from a Surgery Setup Screen.

• If startup preferences are programmed into doctor memory (Options/System), the Procedure Selection Screen is bypassed and the system advances to the domain/

screen selected by the programmer.

When a new domain is entered, all settings are reset to their default values.

Display Windows and their Functions

The LCD display and touch screen is divided into eight windows, shown below in Figure 2-9. Descriptions of the windows and their functions are written on the following pages.

Figure 2-9. LCD DISPLAY AND TOUCH SCREEN - The color display screen for the Accurus^® system displays modes of operation and operating parameters, and also is used for operator input by pressing the touch keys on the screen. This screen is the operator's main tool to input system commands. Operator input is also received from the remote control and the footswitch.

1. Modes Window

This window displays touch keys and their corresponding icons. There are two kinds of keys displayed in this window: Setup Function keys and Mode keys, depending on whether the screen is displaying its Setup Screen or its Surgery Screen. The Mode keys are animated when selected. Figures 2-10 and 2-11 show the two screens.

Figure 2-10. SETUP FUNCTION SELECTIONS IN MODES WINDOW - This section of the display screen offers either setup function selections or surgical mode selections in the modes window.

This illustration shows posterior setup function selections; the anterior setup function selections are similar.

Figure 2-11. SURGICAL MODE SELECTIONS IN MODES WINDOW - This illustration shows posterior surgical mode selections in the modes window; the anterior mode selections are similar.

The mode keys are animated when selected—in this case the system is set in Vit mode for use with proportional vacuum.

2. Global Functions Window

Global functions are available in all setup and surgery screens, regardless of system status or footpedal position (see Figure 2-12). Functions are turned ON and OFF via their icon keys, and their parameter values are adjusted by pressing the global function up/down adjustment buttons. When turned ON, some global functions can be affected from the footswitch.

The Diathermy global function icon key is always enabled for footswitch activation, and its LED readout is always lit; its icon key illuminates bright blue when diathermy is activated.

Global functions may be used in combination with other global functions. Selecting or deselecting one function does not affect the others, with one exception: when VGFI™*

infusion is used, selecting Fluid/Air Exchange deselects Infusion; the reverse is also true.

Listed in the table below are the distinctions between global function icons when they are turned ON and OFF, and what the ON/OFF conditions mean. Descriptions of the global functions are located in sections three, seven, and eleven of this manual.

Table 2-2. GLOBAL FUNCTIONS KEYS - Icon/base keys in the Global Functions window are pressed to turn global functions ON and OFF. The ON/OFF status is listed in this table. (The diathermy global function icon key is always enabled for footswitch activation, and does not adhere to these on/off conditions.)

6. Miscellaneous Window

The Timer Display, Footswitch icon, and Options key are all located in this window (see Figure 2-16). These three features are described below.

• Timer Display

Two Timer Displays can appear in the upper right hand corner of the Surgery Screens and Setup Screens whenever a timer is activated:

General Purpose Timer - This timer appears after being activated in the Options selections. This timer has a blue background, and is activated manually to count either up from zero, or down from a pre-selected value (see the Timer in the Options Functions on pages 2.19 and 2.38).

Elevated Infusion Timer - This timer with the yellow background appears in place of the footswitch icon, and it automatically begins counting up from zero when posterior infusion pressure is greater than or equal to 51 mmHg. It stops counting when pressure goes below 51 mmHg, then begins from zero again each time pressure is 51 mmHg or greater. Pressing the timer display when pressure is less than 51 mmHg removes it from the screen, but it reappears and begins counting from zero again when the pressure returns to 51 mmHg or greater.

Figure 2-16. MISCELLANEOUS WINDOW - This window contains three items: the Timer Display (when activated), Footswitch icon, and Options key.

• Footswitch Icon

When the footswitch is activated this icon changes color. For footpedal activation it progressively displays 1, 2, and 3 in its center to represent the amount of footpedal depression through its detents; when released it displays 0. When the left and right footswitches are pressed the icons at each side change color to indicate activation.

A small letter A, B, C, or D at the bottom of the icon indicates which footswitch map is used. If the map has been modified from the default settings, the map letter will be followed by the prime symbol i.e., A'. Pressing the icon displays a window that shows the current footswitch mapping.

• Options Key

Pressing the Options key presents a drop down menu of selections that offer the user a variety of helpful tools (the selections are described beginning on page 2-19).

Figure 2-17. PRIMARY DISPLAY WINDOW - This window is used to set up and adjust operating parameters, and to view actuals.

Figure 2-18. POPUP WINDOW - Information popups communicate with the user, typically to confirm a critical operator request or to provide status. The popup window disappears when the action is completed, or when the operator presses a popup key to acknowledge the message.

7. Primary Display Window

The Primary Display window is used to select setup options in the Setup Screens, and to adjust/view operating parameters in the Surgery Screens. The operating parameters in the Vitrectomy Proportional Vacuum Surgery Screen are shown below.

8. Popup Window

This window is used to indicate system errors, advisories, and other messages to the user. When a popup window appears, only the keys inside the popup window and the Global Function keys not related to the popup window are available. For a list of system messages turn to section sixteen of this manual.
