To be able to use the extra mouse features, we will have to download the software, present on the SteelSeries website; in the same area we will find an updater for the firmware which we should execute first:

The firmware update tool can work with multiple peripherals from SteelSeries like the Shift Keyboard, Sensei Mouse and so on:

A warning message will appear right before the firmware flash confirmation:

During the flash procedure, we will see a progress bar on the screen, and the CPI LED on the mouse will also blink:

The next step would be to install the SteelSeries Engine application:

Depending on the connected product, the interface of the Engine will change; in our case we have been greeted by a Diablo-themed UI and here we will be able to customize the mouse functions. The UI is divided into multiple sections; on the left we have the list of detected compatible devices, the list of defined profiles and on the right there is the Actions area, along with Tips; the center zone has multiple tabs and in the Buttons area, we will be able to see the current button functions:

By clicking on any of the button functions, we will be able to assign macros, by using the options that will appear on the bottom side:

With the buttons, we can also launch a specific application; for doing this, we also have to point to the Engine to the executable file:

For console commands and quick chat, we can also use the Text Macro feature:

Some of the keys can be disabled when we select Action Type: Disable Key:

Moving further to the Settings tab, we will be able to adjust the CPI settings for the toggle button, the polling rate or customize the LED effects:

The Properties tab helps us associate the current profile to an application or game:

Finally, in the Statistics tab, we can see the total number of button presses per current session or lifetime:
