EQStar User Guide

3.5. Connect the control unit to 12V power via a user-supplied cable with a 5.5mm x 2.1mm power

plug.

After the power switch on the EQStar is turned on, the unit will sound 3 short and 1 long beep that

settings panel to the one noted above in the Windows Device Manager if it is different.

In the EQStar settings panel, click on 'Load settings' to see the current settings of the unit.

The EQStar kit should come with the EQStar correctly set for the mounts supported by this kit. Of
