Note 1:
Values in the table above are temporary approximations of typical consumption, obtained
by measurements at the 12 V power input of the BeFREE 20 (LCD at full brightness) without any
additional Tipro modules and without any other peripherals connected. Terminology for Operating
Modes is taken from “ENERGY STAR Program Requirements for Computers: Version 5.0”.
