User's Manual
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).
