Using the TabletKiosk Modular Expansion System
Your eo a7400 features the TabletKiosk Modular 
Expansion System. This systems allows for the easy 
integration of feature modules that enhance the 
capabilities of your Tablet PC.
Based upon the Universal Serial Bus (USB), the 
modules are hot swappable, meaning you do 
not have to power down your system in order to 
install/remove/exchange a module, and require no 
additional drivers beyond those that may be required 
by the device being added to the system (Barcode 
scanner, magnetic card reader, etc.). 
To add an expansion module:
1.  Remove the two Philips head screws holding 
the Modular Expansion System port cover on 
the top/back of the tablet in place.
2.  Remove the cover to expose the expansion port.
3.  Align the plug of the module you wish to install 
and slide it into place.
4.  Screw the two screws back into place to hold 
the module securely.
5.  After a moment, Windows should detect the 
module and load the required drivers, if they are 
natively available within Windows, or prompt 
you to install the drivers that came with the 
module.
To remove or swap a module, simple follow the 
same procedure, except replace the module you are 
removing with either another module, or the Expansion 
cover plate.
NOTE: If your module contains, or is attached to, a media card reader, external hard drive or other such 
removable media device, be sure to eject the device as you would a standard USB attached data storage 
device before removing it in order to prevent possible data loss/corruption. You can eject the device by 
going down to the System Tray, tapping on the USB Device icon and the selecting the device from the list 
you wish to eject.
Using the Built-in Cameras
Your eo a7400 comes with two built-in digital cameras. The front facing 2.0 Megapixel webcam 
is designed for video conferencing and chatting, while the back facing 5.0 Megapixel camera is 
for shooting still photos and videos.
Both cameras are USB Video standard compliant, and are made to function in any program 
designed to use standard USB cameras, including Skype®. To get you started using the cameras, 
there is a simple, lightweight application that comes preinstalled on the tablet called, simply, 
Camera.
To launch Camera, double tap on its icon on the desktop, or if you do not have a desktop 
shortcut for Camera, choose it from the Start Menu in the "All Programs > TabletKiosk" submenu.
When the application starts, you'll be presented with the main application interface.
Remember to screw the module into place 
to prevent it from coming off while in use. 
Be sure to store the screws that attached the 
cover in a safe place so as not to lose them.
