Bluetooth keyboard to input the data into your computer.

off without repeating the pairing procedure. They will connect
automatically again.
3. How to use the keyboard
After successful launch of the keyboard enjoy now 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. The status LEDs on the front side of your Bluetooth keyboard inform you about the current
operating condition.
3.1 Meaning of status LEDs

It is used to indicate the Bluetooth keyboard is in pairing mode (searching a Bluetooth
receiver). When the pairing button is pressed, the LED flashes till a receiver has been found
or the relevant computer stops pairing in advance.
• Reconnecting-LED
It is used to indicate that the Bluetooth keyboard is reconnecting to the already founded
receiver after waking up or power up via the accordant authority (registered password or
PIN).
• Battery Low-LED
It is used to indicate that the battery is below 2.4 Volts. It keeps on until new battery is
installed or the battery is total used up. It is flashing only while the keyboard is not in sleep
mode.
3.2 Operating modes of the Bluetooth keyboard
• Sleep-Mode
After 15 minutes of no keyboard input, the Bluetooth keyboard will automatically enter into sleep mode to
preserve battery power.
• Wake up-Mode
To wake the Bluetooth keyboard up, press any key of the keypad (not the L and R button of touchpad or the
touchpad itself!).

After reactivation the keyboard reconnects automatically with the Bluetooth dongle. Depending on
environmental conditions for the radio transmission it takes less than a second or up to several minutes to
reconnect. In the meantime, the Reconnection-LED is blinking.
