System User's Manual
3.3.8 Display Area
The Display area is located at the center of the Keypad/LCD Display. It is used to
present information to you, and to show the soft key definitions that allow you
to perform routine operations.
The LCD Display is programmed to automatically dim after 5 minutes of inactiv-
ity.To return the brightness to normal, press one of the unassigned keys (such as
the rightmost soft key).
More information on displays is presented in Section 5 — Reference.
3.4 Door Interlock Switch
When the door of the instrument is opened, a door switch senses the condition
(see Figure 6).This switch tells the system to immediately stop the rotor drive
motor,start the door open timer, and discard the results of any tests in progress.
Because vial test results of tests in progress are discarded when the door is
opened, door openings should be minimized if possible.
3.5 Floppy Disk Drive
The floppy disk drive is located on the front of the instrument, at bottom left. Its
primary purposes are to enable you to save data to floppy disk, and to perform
software updates when they are released. See Figure 9.
3.5.1 Floppy Disk Indicator
The Floppy Disk Drive Indicator light is on the left side of the drive below the
insertion slot. When off it indicates that no activity is occurring in the drive.
When on or flashing, it indicates that the disk drive is accessing a floppy disk.
Do
not attempt to eject a floppy disk while this indicator is lit.
