The keyboard includes an integrated trackball with two mouse buttons, an extremely flat overall height of 20 mm and a lightweight housing. It retains all standard keyboard functions in an 83/84-key layout and works with standard operating system drivers.

How to use

Connect the keyboard to a PS/2 port on the target system using the attached 1.75 m cable.

Place the keyboard on a stable surface or mount as required for 19-inch applications and adjust hand position for comfortable use of both keys and trackball.

Recommendations

For continuous heavy use, ensure the host system recognises PS/2 input and that the keyboard is mounted or placed to prevent dust buildup around the trackball. Periodically check key function and clean the trackball according to manufacturer guidance to maintain precision and longevity.
