1. Introduction
The ergonomic mouse/trackball solution from DIGITUS® is easy
on your joints by reducing arm and wrist movement. It
promotes a natural hand posture, because navigating is
primarily done via the optical trackball. The mouse connects to
your PC, Mac or Android device either via Bluetooth or the
included USB receiver. Up to 3 devices can be assigned and
switched at the touch of a button if necessary. The resolution
of the optical sensor can also be changed to 3 different
sensitivity levels, allowing the mouse to be optimally adapted
to the respective device or application. In addition, the
integrated buttons for the “forward/backward” functions make
your daily work easier. The integrated 600 mAh battery ensures
long operating times and, thanks to the USB-C™ charging port,
faster charging times.

8. Attention
Because this product uses the optical induction way, needs to
work in the diffuse reflection surface, asks the user to pay
attention to the use environment. It is recommended that users
use it on the diffuse surface, not on the specular surface (such
as glass, etc.) to avoid inflexible mouse movement.
This is a Class A product. In home environment, this product may cause radio
interference. In this case, the user may be required to take appropriate
measures.
