7.2 Start-Up
Following the power-up reset, the DOU performs a self-test. Data
is read from the inverter once the test has been completed suc-
cessfully. The LEDs light up in sequence during this phase. A start
screen appears on the LCD and a status bar indicates the duration
of the start-up process.
When you start up the DOU for the first time, select the menu
language using the general keys "<" and ">". The languages that
are available are indicated using their respective country-specific
abbreviations (the same as those found on car number plates).
The language that is currently selected is displayed on a black
background. Once you have confirmed the selected language by
pressing the ENTER key, the next menu opens. In order to comply
with international requirements, all of the displays up to the one for
language selection are displayed in English.
