1. Installation
1.1 System Requirements
This keyboard requires a PC with USB connection and one of the following operating systems:
Windows 98SE / ME / 2000 / XP / Vista
For the installation of the keyboard under the mentioned above operating systems you need NO
special driver!
1.2 Installation of the USB receiver
In order to install your keyboard, please perform the following steps:
Connect the included USB receiver (dongle receiver) to a free USB port on your computer.
Advise:
Please ensure, that the USB receiver has a minimal distance of 20 cm to metallic dividing walls,
other computer cases, monitors, ZIP drives, loudspeakers and switching power supplies.
All mentioned above state-of-the-art operating systems with Plug & Play support will recognize
your keyboard automatically and load the required drivers. During the phase of installation your
operating system informs you via changing Pop-up information windows on the task-bar about
the current status of installation. Please be patient, until the system informs
you finally about the successful installation.
The USB receiver is now ready for operation.
1.3 Installation of the keyboard
Recommended requirement for that is the successful installation of the USB receiver under
point 1.2.
If you haven’t done yet, remove the covering of the battery case on the bottom of your keyboard.
Install the included batteries of type AAA 1.5 V considering the right polarity in the battery case.
Switch the I/O sliding switch to ON position!
Advice:
The USB receiver and the keyboard are factory-made already synchronised on the same
channel. Normally you have not to make a new-synchronisation (as described under point 2.4).
The keyboard is immediately functioning.
Now you can check the functionality by pressing any key of your keyboard. If you press the
Windows key, there has to open for instance the Windows Pop-up menu down left on your
screen. If so, your
wireless keyboard is working correctly now. If not, please synchronise the USB receiver and the
keyboard again like described under point 1.4.
Advise:
Should the functionality be influenced by other users applying their wireless keyboard close-by,
make a new-synchronisation as described under point 1.4.
1.4 New-synchronisation of the radio channel
The keyboard is equipped with the newest radio technology allowing in the easiest manner to
make a new-synchronisation.
In contrast to conventional or older wireless keyboards on the market here is to press the
PAIRING key on the back side only 1 time, whereby the new synchronisation signal is
transmitted to the USB receiver. Thereby a complete, extremely comfortable handling from the
user’s location is possible without the need to stand up for pressing the synchronisation
key of the receiver, which is usually located in the USB port of the PC.
The process of synchronisation can take up to 10 seconds and is signalised by flashing up of
the PAIRING-LED (left LED on front side of the keyboard), which goes out after successful
procedure.
The keyboard is now re-synchronised.
Check now the functionality of the keyboard like described under point 1.3.

In implausible case the keyboard does not work even after new-synchronisation, you have the
following options to solve this problem:
Repeat the procedure including the hardware reset of the USB receiver (conventional
synchronisation) by pressing at first the LED key on the USB receiver (blue LED of the USB
receiver flashes 3 times in a row) and only now the PAIRING key on the back side like
mentioned above. In very rare cases it is necessary to repeat this routine several times until
the right “radio channel” was found.
2. How to use the keyboard
After successful launch enjoy now during the operation a free and independent choice of
location up to approx. 10 m distance to the PC. More or less range can be caused, like
mentioned above, by metallic dividing walls, other computer cases, monitors, ZIP drives,
loudspeakers, switching power supplies etc., but also by different loading capacity of the
batteries. For this, the status LEDs on front side of the keyboard give you information about
the current operating condition.
2.1 Meaning of status LEDs
Pairing-LED
indicates that the keyboard and the USB receiver are in Pairing-Mode, that means during
manual initiation of the new-synchronization routine to one shared “radio channel” (ID). It goes
out after successful synchronisation.
Transmitting-LED
indicates during key actuation that all input information have been sent out successfully per
radio transmission from the keyboard.
Battery Low-LED
indicates that the load condition of the batteries is below 2.4 Volt. It flashes until a new battery
was inserted or the battery was used up completely.
Besides it flashes only when the keyboard is not in Sleep-Modus (idle state).

2.2 Special operation modes of the keyboard
Sleep-Mode
When 30 minutes happens no input in your keyboard respectively touchpad, the keyboard
turns automatically into Sleep-Mode (idle state) to save battery capacity.
Wake up-Mode
For activating the keyboards from Sleep-Mode press any key on your keypad
(not the left or right mouse function key of the touchpad or the touchpad itself!).
Reconnect-Mode
After reactivation the keyboard connects automatically again with the USB receiver.
Depending on environmental conditions for the radio transmission it needs for that
between less than 1 second up to few minutes.
