Every device is different!
The operating instructions contain information on effective and reliable use.

  • Read the operating instructions carefully.
  • Keep the operating instructions and pass them on to other users.

For your safety

Risk of choking from swallowing small parts

  • Keep the device out of the reach of children under 3 years.
    RSI stands for “Repetitive Strain Injury”.
    RSI arises due to small movements continuously repeated over a long period of time.

  • Set up your workspace ergonomically.

  • Position the keyboard and mouse in such a manner that your upper arms and wrists are outstretched and to the sides of your body.

  • Change the inclination of the keyboard by mounting the support bar.

  • Take several short breaks, with stretching exercises if necessary.

  • Change your posture often.

Avoiding damage

Damage to the keyboard

  • Do not remove the key caps. The magnets can wipe storage media and damage mechanical watches
  • Do not place any storage media such as magnetic cards or external hard drives, or mechanical watches within 10 cm of the mouse or the keyboard support bar.

Connecting devices to the PC/laptop

You can connect the devices to the PC/laptop via Bluetooth or via a 2.4 GHz wireless connection using the receiver.

Connecting the devices via Bluetooth

Bluetooth version
You need a PC/laptop with a Bluetooth receiver that supports at least Bluetooth 4.0.

  1. Open the search for Bluetooth devices on your PC/laptop (for example via Start > Settings > Devices > Bluetooth).

  2. Follow the software instructions.

  3. Slide the switch on the back of the keyboard or the bottom of the mouse to “BT”.

  4. Activate the keyboard/mouse Bluetooth connection by pressing the button next to the BT switch.
    The LED flashes blue. If the LED does not flash blue:

    • The keyboard/mouse is already connected to another PC/laptop. Switch it off or deactivate that connection.
  5. Follow the software instructions.
    The LED goes out and the device is connected to your PC/laptop. If the LED rapidly flashes red, the connection has failed.

    • Try again.

Connecting devices via the receiver
The receiver is in the compartment on the bottom of the mouse and is held by a magnet.

  1. Pull the receiver out of the housing of the mouse.
  2. Connect the receiver to a USB 2.0 port on your PC/laptop if possible (this usually has a white or black guide).
  3. Slide the switch on the back of the keyboard or the bottom of the mouse to “RF”.
    The LED on the back of the keyboard or the LED on the mouse will briefly flash red to confirm. The keyboard/mouse is connected to your PC/laptop.

Storing the receiver in the mouse

The receiver is so small that it can stay in the USB socket of a laptop while being transported. To avoid any damage, you can also pull out the receiver and deposit it in the mouse to protect it from dirt and loss.

Raising the angle of the keyboard

You can raise the angle of the keyboard by mounting the supplied support bar on the bottom of the keyboard.

  1. Turn off the PC/laptop or deactivate the connection.
  2. Use the pins of the magnetic support bar to plug it into the asymmetrically arranged recesses on the bottom of the keyboard.

Setting the DPI rate of the mouse

The speed of the mouse pointer increases with the level of the DPI rate.

  • Press the DPI button on the top of the mouse.
    The LED flashes according to the setting:
    1x = 1000 dpi, 2x = 1600 dpi, 3x = 2400 dpi
    The setting is saved in the mouse and is retained even when the mouse is switched off.

Charging the batteries

If the voltage of the keyboard or mouse batteries drops, depending on the device, the LEDs of the keyboard or the DPI button flash ten times, after this the signal stops.
This happens if you work with one of the devices after starting the PC/laptop or if you rouse it from sleep mode. Charging the batteries in good time prolongs their service life.

  • Connect the charging cable to the socket on the device and a USB port or USB network adapter.
    Your power source (PC/laptop) must be switched on. During the charging process you can continue working, and the LED on the back panel of the keyboard or the DPI button on the mouse will light up red. When the LED on the back panel of the keyboard or the DPI button of the mouse goes out, the batteries of the device are fully charged. The charging circuit prevents overcharging.

Switching the devices on and off

When not in use, the devices switch to sleep mode, which requires much less power. They switch on again automatically as soon as you press a button. Because they still consume some power in energy-saving mode, you should switch them off manually for extended periods of non-use or for transporting.

  • Slide the switch on the back of the keyboard or the bottom of the mouse to the appropriate position:
    Off = keyboard switch in middle position/mouse off
    On (wireless) = RF
    On (Bluetooth) = BT

Cleaning the devices

Switch the devices off.

NOTE! Aggressive cleaning agents and liquids can damage the devices.

  • Do not use solvents such as benzene, alcohol, scouring agents or abrasive scourers for cleaning the devices.
  • Prevent liquid from getting inside the device.
    2Clean the devices with a slightly damp cloth and some mild detergent (such as washing-up liquid).
    3Dry the devices with a soft, lint-free cloth.

If the devices do not work

  • Switch the devices off and on again.
  • Charge the devices via the charging cable (see 7 “Charging the batteries”).
  • Remove any objects causing interference between the devices and the PC/laptop. Interference is caused in particular by metallic or electrical objects such as cables, loudspeakers or USB hubs.
  • Reduce the distance between the devices and the PC/laptop.
  • Should any interference be encountered when using USB 3.0 devices right near the receiver: Use a port that is further away, an additional cable, or a USB hub for the receiver or USB 3.0 device.

Rectifying a Bluetooth connection fault

  • Check whether the internal receiver of your PC/laptop supports at least Bluetooth standard 4.0. Lower versions are not supported.

  • If your PC/laptop is in standby mode, it cannot be woken up using Bluetooth devices. Switch on the PC/laptop manually.

  • If the devices are already connected to another PC/laptop, you cannot establish a parallel connection. Turn off the first PC/laptop or deactivate the connections.
    Operation of several Bluetooth devices on a PC/laptop
    When too many Bluetooth devices are connected, it may be too much for the Bluetooth receivers in the PC/laptop.

  • Turn off any unnecessary Bluetooth devices.

  • Remove the connection to the keyboard/mouse in the Bluetooth software and add it again as a new device.

  • Use an external Bluetooth receiver.

  • Connect the devices using the receiver.

Rectifying a connection fault using the receiver

  • Connect the receiver to a USB 2.0 port on your
    PC/laptop (this usually has a white or black guide). Malfunctions occasionally occur on USB 3.0 ports (blue guide).

  • Connect the receiver to another USB 2.0 port on the PC/laptop.

  • Reduce the distance between the receiver and the devices by connecting the receiver to a USB port that is close to the devices.

  • Use a USB extension cable to place the receiver as close to the devices as possible.

Device disposal

  • Do not dispose of devices with this symbol in household waste.
  • Dispose of the devices in accordance with statutory regulations – at your local dealer or at municipal recycling centers.
