Repetitive Strain Injury (RSI): RSI can result from small, continuously repeated movements. Ensure an ergonomic workspace, position the keyboard and mouse correctly, take frequent short breaks with stretching exercises, and change your posture often.

2. Switching the Keyboard On/Off

The keyboard enters a low-power sleep mode after 30 seconds of inactivity, turning off LEDs and illumination. It reactivates upon the first key press. For longer periods of non-use or for transport, manually switch the keyboard off using the switch on the back: Off = O, On = I.

3. Connecting the Keyboard to a Device

Connect the keyboard via USB cable, Bluetooth, or the 2.4 GHz wireless receiver. Bluetooth is convenient for multi-device use and allows pairing up to 3 devices.

3.1 Connecting the Keyboard via Cable

1. Turn the keyboard on (switch to 'I').
2. Plug the keyboard into a USB port on your device.
3. While holding the FN key, press the USB key ( ). The 'USB/Battery' LED above the arrow keys ( ) will glow green.

3.2 Connecting the Keyboard via Bluetooth

The keyboard supports up to 3 Bluetooth channels for connecting to different devices.

12. Troubleshooting

• If CHERRY key functions are not working, ensure it's not deactivated (see section 8).
• Turn the keyboard off and on again.
• Try a different USB port.
• Test the keyboard on another PC/laptop to rule out a defect.
• In the PC's BIOS, ensure 'USB Keyboard Support' or 'USB Legacy Mode' is enabled.
• Charge the keyboard via USB cable (see section 9).
• Remove potential interference sources (metallic or electrical objects like cables, speakers, USB hubs) between the keyboard and PC/laptop.
• Reduce the distance between the keyboard and PC/laptop.
• If interference occurs with USB 3.0 devices near the receiver, use a more distant port, an extension cable, or a USB hub.

12.1 Rectifying Bluetooth Connection Faults

• The PC/laptop cannot be woken up from standby mode via Bluetooth devices. Manually turn on the PC/laptop.
• If the keyboard is already connected to another device on the selected channel, a parallel connection is not possible. Turn off the other device or disable its connection.
• Multiple Bluetooth Devices: If too many Bluetooth devices are connected, the PC/laptop's Bluetooth receiver may be overloaded. Turn off unnecessary devices, remove and re-add the keyboard in Bluetooth software, use an external Bluetooth receiver, or connect via the receiver. If using different Bluetooth channels, switch channels if necessary (see 4.1).

12.2 Rectifying Receiver Connection Faults

• Connect the receiver to a USB 2.0 port (typically white/black guide). USB 3.0 ports (blue guide) may sometimes cause malfunctions.
• Try a different USB 2.0 port.
• Reduce the distance between the receiver and keyboard by using a nearby USB port or a USB extension cable.

13. Palm Rest and Feet

A palm rest and feet are available as accessories.

14. Disposing of the Keyboard

The keyboard contains a non-replaceable lithium-ion battery. Electrical devices and batteries contain substances harmful to health and the environment. Dispose of the keyboard and batteries according to legal regulations.
