Product information

Description

DEFENDER DATUM MM-285 Office ambidextrous RF wireless optical 1600 DPI black is a compact office mouse designed for everyday computer work. The device combines an ambidextrous shape with optical tracking and a 1600 DPI sensitivity level, offering responsive pointer control for browsing, document editing and standard office applications. Connection is provided by an RF wireless interface for cable-free use, and a simple three-button layout with a scroll wheel ensures basic navigation and selection tasks are covered.

Advantages

The ambidextrous form factor supports both left- and right-handed users without favoring one hand, while the 1600 DPI optical sensor provides accurate cursor movement suitable for typical office tasks. RF wireless connectivity removes cable clutter and simplifies setup with a plug-and-play receiver. The mouse is lightweight and compact, making it easy to carry between workstations or store in a bag. The three-button design with a scroll wheel delivers intuitive operation for common commands and navigation.

How to use

Install the RF receiver into an available USB port on the computer and allow the operating system to recognize the device. Insert the required batteries into the mouse as indicated in the battery compartment. Place the mouse on a flat surface and adjust hand position to the ambidextrous shape for comfort. Use the left and right buttons for selection and context actions and the scroll wheel to navigate long documents and web pages. If pointer speed needs adjustment, change mouse sensitivity settings within the operating system to match personal preference.

Usage recommendations

For reliable wireless performance, keep the RF receiver within a few meters of the mouse and avoid placing large metal objects between the mouse and receiver. Use on a clean, flat surface or mouse pad for best optical tracking. Replace batteries when cursor response becomes inconsistent to maintain stable operation.
