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

Form factor: Mini keyboard with integrated numeric function
Layout: QWERTY, UK English

How to use

Connect the keyboard to an available USB port on your desktop or notebook using the supplied 1.9 m USB cable.

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.
