## Long description

The SoftSkin coating offers a refined matte finish that resists fingerprints, while membrane keys deliver silent typing with tactile response. The 1.9 m USB connection ensures reliable, simple setup on any USB-enabled PC or terminal.

Key specifications
Model: KeySonic ACK-540U+ (DE)
Layout: QWERTZ (German)
Interface: USB (1.9 m cable)
Switch type: Membrane
Form factor: Mini keyboard with integrated Smart-Touchpad
Colour: Black with SoftSkin matte coating
How to use
Connect the keyboard to a USB port using the attached 1.9 m cable — no drivers are required for basic functionality on most operating systems. Use the integrated Smart-Touchpad for cursor control; two-finger gestures perform vertical scrolling while three-finger gestures can invoke context-menu actions similar to a right-click. Type as usual on the QWERTZ German layout and rest your wrists on the built-in ergonomic support during extended use.
Usage recommendations
For optimal performance, place the keyboard on a stable surface and ensure the USB plug is fully inserted. Clean the SoftSkin surface gently with a soft, slightly damp cloth; avoid harsh solvents. This product is intended for office and kiosk environments rather than intensive gaming.
