Product information

Description

The KeySonic ACK-540U+ is a mini wired office keyboard with an integrated Smart-Touchpad and UK English QWERTY layout. Finished in matte black SoftSkin coating, it includes blue status LEDs for Caps, Num and Scroll Lock and offers full-size layout functionality in a compact housing. The keyboard uses X-Type membrane technology to provide tactile feedback with an extremely quiet keystroke and connects reliably via a 1.9 m USB 2.0 cable.

Advantages

The compact design saves desk space by integrating a numeric keypad into the letter keys, activated via a function key. The built-in Smart-Touchpad with two mouse buttons removes the need for a separate mouse. The SoftSkin surface and rounded design improve typing comfort, while the X-Type membrane ensures quiet operation and clear tactile response. Wired USB connection provides stable and consistent communication with desktop or notebook computers.

Suitable for

  • Office tasks and data entry in limited workspace
  • Notebooks or desktop setups where an external mouse should be avoided
  • Shared workstations where quiet typing is preferred

Key specifications

  • Model: KeySonic ACK-540U+
  • Interface: USB 2.0 (cable, 1.9 m)
  • Form factor: Mini keyboard with integrated numeric function
  • Layout: QWERTY, UK English
  • Switch type: X-Type membrane
  • Colour: Matte black SoftSkin
  • Integrated Smart-Touchpad with left and right click buttons

How to use

Connect the keyboard to an available USB port on your desktop or notebook using the supplied 1.9 m USB cable. Use the function key to enable the integrated numeric keypad on the letter keys when numeric input is required. Operate the cursor and perform clicks using the Smart-Touchpad and its two mouse buttons. The keyboard is plug-and-play on most systems; no additional drivers are typically required.

Usage recommendations

For optimal comfort, place the keyboard on a flat surface and position your wrists neutrally. Enable the numeric function only when needed to avoid accidental number input. Clean the SoftSkin surface with a soft, slightly damp cloth and avoid strong solvents to preserve the coating.
