USING THE DURANDAL ULTIMATE
Ok since the Durandal Ultimate comes with a software CD you have two options, either use the control panel version included or download the latest one (if there is one) from the Tesoro support page.
Once you connect the keyboard to your system the Tesoro logo lights up on the LED area (looks nice doesn't it?).
The control panel is extremely easy to use but it really doesn't offer much in terms of customization so the only thing you can do is to enter up to 10 macro commands and store them to each of the 5 available profiles.
Leaving the control panel out you can adjust the illumination of the keys via the 8 and 2 keypad keys in conjunction with the Fn key. The available illumination settings are low/medium/high/pulse/off (above you see the off/Low/High settings).
