The useful details
Know what
you’re getting.
The MK850 pairs a full-size keyboard with a contoured mouse. A cushioned palm rest, concave keycaps and adjustable keyboard tilt support different desk positions.
Connect with the included Unifying receiver or Bluetooth and use Easy-Switch to select paired devices. The keyboard and mouse have separate operating-system requirements.
The keyboard uses two AAA batteries and the mouse one AA battery, supplied pre-installed. The keyboard claim is 36 months based on two million keystrokes per year.
The set is useful for a desk that serves more than one compatible device. Easy-Switch keeps device selection on the input controls, while the Unifying and Bluetooth options allow the connection method to suit each host. The keyboard's 0, 4 and 8-degree positions and cushioned palm rest provide different working arrangements without promising a medical benefit. Check the requirements for both devices separately when planning a mixed-platform setup; a keyboard-supported system does not automatically establish every mouse feature on that system.
