Introduction
Congratulations on choosing the VKB Virtual Keyboard for Windows 2000 and
XP systems. So throw away that old clunky keyboard, free up valuable desk
space and put an end to sticky keys.
Please take a few minutes to review the simple operating instructions in order
to get the most out of your keyboard.
General Production Description
The Virtual Keyboard is a miniature, stand-alone accessory that emulates the
function of a standard, full-sized keyboard. The Virtual Keyboard can connect
via Bluetooth to almost any information appliance, including: PCs, Tablet PCs,
Laptops, PDAs and Smartphones, with the use of an appropriate driver.
Laser Safety Precaution
The Virtual Keyboard device emits two laser beams. One beam (red) projects
the keyboard image, and the other beam (invisible) is used for sensing which
keys have been touched.
The radiation levels of both laser beams do not exceed the Accessible
Emission Limits of Class 1, as defined by the international standard IEC
60825-1 (A2) and the American standard 21 CFR 1040.10. The Virtual
Keyboard device is, therefore, a “Class 1 Laser product”.
This means that the Virtual Keyboard device is safe under reasonably
foreseeable conditions of operation.
Although the emitted laser beams are safe (as defined by the above standard),
it is highly recommended not to stare directly into laser beams.

Virtual Keyboard, your Windows PC and Bluetooth
The Virtual Keyboard you have is equipped with Bluetooth, a short-ranged
wireless communications technology allowing you to communicate with your
Windows PC up to 10 meters away without the need for a physical connection.
The keyboard Bluetooth supports both the HID (i.e. Human Interface Devices)
service as well as the SPP (Serial Port Profile) service. For information on
which Bluetooth services are provided by your computer, refer to the
documentation on the Bluetooth software installed on your PC.
If your computer Bluetooth software supports HID no VKB Driver software
installation is required.
If your computer Bluetooth software does not support HID, you may use SPP
and you’ll need to install the VKB Driver on your computer.

Installing the driver on your Windows PC
1) Insert the VKB CD into a CD-ROM drive on your computer.
2) Insert the Bluetooth Virtual Keyboard & User Guide Disk into a
CD-ROM drive on your computer. (The CD should run automatically
however if it does not start by itself, please open the CD and run
setup.exe)
3) Follow the onscreen prompts to arrive at the PCs page.

…and connect.
11
Pairing your Keyboard
Preparing your keyboard for pairing
Place the Virtual keyboard on a flat surface and turn it on. The blue LED at the
top should flash at about twice a second. This signifies that the Virtual
Keyboard is currently “unpaired” with any device. If this is not the case, please
see “Resetting the Device for Bluetooth Pairing” on page 25.
Pairing with your Computer

nearby Bluetooth devices.
12
3) Once the VKB Keyboard is detected, press Next to initiate the pairing
process.
4) When prompted, select “Let me choose my own passkey” and enter a
Passkey of between 1 and 8 characters.
13
5) Press Next and then enter the same Passkey followed by <Enter>
using the keyboard image projected by the Virtual Keyboard.
6) Your Virtual Keyboard is now successfully paired with your Windows
PC.
Note: Remember the number of the COM port to which the Virtual Keyboard
has been assigned. You will need this information later.
14
Connection with your Computer
Once the keyboard and computer are paired, the Discover Services function
on your computer will allow you to connect via HID (if supported on your
computer) or SPP. Check your computer’s Bluetooth software to see which
services your computer provides and ensure that your preferred service is
enabled.
Connecting via HID Profile
If you would like to use HID Profile, select HID and connect. At this point your
computer may start to install HID related modules. This is normal, please wait
for the installation to complete. Once finished, the blue LED on the keyboard
will go on signifying a successful connection. You are now ready to use the
keyboard.

for optimal use. If you are experiencing missed key presses, try raising the
setting. If you are experiencing extra key presses, try lowering the sensitivity.
Reset to Default
Pressing the Reset To Default button will cause the Virtual Keyboard and
driver to reset the sensitivity to the keyboard’s factory settings.

Time-Outs
To conserve the battery of the Virtual Keyboard it can be set to switch off
automatically if it has not been used for a while. There are two separate
settings which may be adjusted to suit you. Projection Timeout switches off the
projected keyboard. Auto Timeout switches off the whole device. When a
period exceeding the Projection Timeout has elapsed without typing on the
keyboard, the projection will automatically turn off. Pressing anywhere will
cause the keyboard to be projected again. When the Auto Time-Out has
elapsed the Virtual Keyboard will switch off. If this occurs, press the button on
the Virtual Keyboard to turn it on again.

General Handling Instruction
Micro-switch
The device is equipped with a micro-switch which disables the Virtual
Keyboard lasers when the device is picked up. This is a safety measure. Do
not attempt to override this micro-switch.
General Maintenance
• Avoid touching the keyboard sensing receiver window.
• Never touch the keyboard projection element.
• Avoid exposing the keyboard to moisture or extreme temperatures.
• Do not disassemble or try to touch the inside of the device.
• Do not attempt to charge the device with a different charger than the
one provided by VKB.
• If the windows become dirty clean only with a soft, lint free dry cloth. Do
not use any solvents or cleaners.
Resetting the Device for Bluetooth Pairing
1) Turn the keyboard on and gently insert the end of a paperclip into the
reset hole found under the rubber flap on the right side of the keyboard.
Press for about half a second and then remove the clip.
2) After about 2 seconds, the keyboard will emit a short “beep” and the
LED will flash blue.
3) Pick up the keyboard and wait for it to turn off,
4) Place the Virtual Keyboard back on the flat surface and turn it on.
5) The Virtual Keyboard is now ready for pairing/bonding.
