Introduction
QUICK TOUR OF THE NOTEBOOK
Take a moment to become familiar with the locations and functions of all controls. It is recommended that you first go through the notebook's user guide for more information on how to operate all of the features.
Main Components
This section describes the main features of the NEC Versa 2400 computer.
Color LCD Display Panel
Both the NEC Versa 240X and 243X series have a built-in 11.3" passive matrix dual scan DSTN color liquid crystal display (LCD) which you can adjust and tilt to your desired viewing position. The LCD provides 800x600 pixel resolution with a maximum of 256 colors, and supports simultaneous display with an external VGA monitor. The LCD screen also uses Cold Cathode Fluorescent Tube (CCFT) backlighting which consumes most of the power from the notebook. To save battery power, the system has an advanced power management feature that powers down the LCD when it has not been used for a predetermined amount of time. You can adjust the brightness and contrast level of the LCD by pressing the "Fn " key (lower left corner) and the desired brightness or contrast keys (lower right corner) at the same time.
Power Switch/LCD Cover Switch
The power switch button, when pressed, turns on the notebook's power. Press it again to turn computer power off. Whenever the notebook is in "Save-to-file" suspend mode, the power switch button serves as a manual resume switch that allows you to continue your application work at the place you last left it before the suspend mode was activated. NOTE: Always wait for a few seconds between turning off and turning on the power. Likewise, check to see if the power switch is turned off before installing the power supply. On the top of the unit underneath the right hinge is the LCD cover switch button. This button automatically depresses and releases when you lower or raise the LCD display panel. Depending on your power management settings, this button will either switch the notebook to the Suspend mode or will shut off the LCD when you close the cover.
Introduction
1-5
NOTE: If the NEC Versa 2400 has been left unused for a prolonged period of time the battery may become completely discharged. It will then be necessary for you to reconnect the AC adapter for approximately 30 minutes before the battery will begin to recharge normally.
Status Panel and Power Indicator
Directly below the LCD display, in the center near the right hinge, is the Suspend Mode LED Displays. These LEDs provide an easy way of determining what the power mode the unit is in at the moment. Below these two LEDs is a row of seven more. These LEDs will light to indicate whether a device is being accessed, whether an operation is being done, or if a certain mode is or has been activated.
Keyboard
The notebook has a built-in 87/88-key keyboard that provides complete emulation of a fullsized IBM AT-enhanced keyboard with function keys and screen/cursor control keys.
Figure 1-3
Standard Keyboard Layout
The notebook keyboard includes an embedded numeric keypad, and some special function keys that are activated by pressing the key together with another key. These special function keys (more popularly known as "hot keys") allow you to control and adjust some of the notebook's functions like; display controls, speaker volume, and power management features. The embedded numeric keypad is activated by pressing the key. Once the key is pressed the upper blue symbols will become active.

Function This key combination puts the system in Suspend mode.
Fn Key Combination Summary
The notebook's keyboard also features an embedded editing keypad, which offers an optional method for editing and moving within documents. The embedded editing keys are color coded in blue and embedded on the front side of the embedded numeric keypads. To use these editing keys, first press the Num Lock key and then combine the Shift key + the desired function key to enable these editing keys. When the embedded editing keys are operational, the Num Lock LED will be activated. To return to normal keyboard operation, press the Num Lock key again. When the Num Lock LED glows the embedded numeric key pads are activated.
Introduction

VersaGlide
In front of the keyboard panel, in the center of the palm rest typing surface, is the VersaGlide pointing device. The buttons below the glide pad are configured (by default) as the left and right button respectively. While the button to the right is configured as the right button on the mouse. Moving the pointer on the screen is done by moving your finger over the surface and directing the pointer where you want it to go. The VersaGlide is compatible with the standard PS/2 mouse and can be activated using the normal DOS or Windows IBM or PS/2 mouse driver.

Introduction
The Right Side of the Notebook
This section describes the features on the right side of the NEC Versa 2400 computer.
Built-in Floppy Disk Drive
On the right-front side of the notebook you will find the floppy disk drive which supports 3.5-inch 1.44MB high density (HD) diskettes or 720KB double-sided (DS) diskettes. Insert the floppy diskette with the metal shutter towards the drive and the diskette label facing up. To remove the floppy diskette, you press the eject button found on the upper right of the floppy disk drive.
PCMCIA Slot Compartment
The PCMCIA slot compartment houses two card slots that support two PCMCIA Type II devices or one Type III device. Open the compartment door to view the PCMCIA slots. Insert Type III cards into the lower slot. Insert the card with the pin sockets facing towards the drive and the label facing up. To remove the PCMCIA card, push on the eject button to release the pin connections and slowly pull out the card. The NEC Versa 2400 Series also comes with DOS/Windows PCMCIA drivers for supporting various PCMCIA cards like modem cards, network cards, and other I/O and memory cards. The LED Status Bar, likewise, provides lights to indicate when the computer is accessing the inserted PCMCIA cards. The upper PCMCIA slot is referred to "Slot 0" while the bottom slot is referred to as "Slot 1". Slot 0 always takes precedence over Slot 1 in drive designations.
