Introduction
The VRC 6940 is a rugged computer terminal that can be installed in a vehicle or mounted on a wall or workbench. It allows you to gather information quickly, easily and accurately using the keyboard or an attached scanner. The VRC 6940 transfers the information to a base station Access Point (AP) through a Symbol Spectrum24® radio network. Then the AP transmits that information to a host computer for processing.
VRC 6940 terminals can run a variety of software applications. For help in using an application at your facility, refer to the application documentation or ask your System Administrator.

Q u i c k R e f e r e n c e
The terminal restarts and you can log in to an application. If you have problems opening an application after resetting the terminal, contact your System Administrator.
Note: If you reset a terminal, you may lose any unsaved data.
Entering Data
You can enter data into a VRC 6940 terminal by using the keyboard or an attached scanner.
Tips for Using the Keyboard
•Press only one key at a time. Pressing two or more keys at the same time can cause an error.
•Press the keys in correct sequence. When key sequences are listed for an application, press the keys one at a time in the order they are listed.
•Auto-repeat feature. Some applications use the auto-re- peat feature of the keyboard. If they do, when you press and hold a key, the key will repeat until you release it.
•Application functions. The keyboard may have different functions depending on the application you are using. Refer to your application documentation for more information.
Attaching a Scanner

Charging the Internal Battery
The VRC 6940 has an internal battery that provides power and saves your session if there is a temporary fluctuation, disconnection, or interruption in the unit’s main power supply. The internal battery recharges itself from the terminal’s main power supply. You cannot use it to operate the unit. For more information, see Installation and the Internal Battery on page 16.
Moving to a Different Power Source
To move a VRC 6940 terminal from one location to another:
1.Save all data you are working with, and close all applications.
2.Press the ON/OFF key to suspend the terminal.
3.Make sure a power source is ready in the new location.
4.Unplug the external power cable from the Power Connector on the back of the terminal.
5.Remove the terminal from its current mounting.
6.Move the terminal to the new location and mount it.
7.Plug the external power cable into the Power Connector. For more information on installation and power, see page 8.
