Preventing changes of set-up parameters
To avoid unintentional modification of the
Set-up parameters, it is possible to block the
access to the Set-up Mode, by means of a DIP
switch situated at the Display Board A3.
Note!
If the DIP switch is set to blocked,
pressing the SW1 enables the user to enter
the set-up menu within 10 seconds. After the
time elapses the menu will be blocked again.

Please note that the acceptable voltage range for all commercial aircraft is 115V ±3V. This range is
even tighter for some aircraft.
Enter the Setup Menu and then scroll up or down to the Output Voltage submenu. Press the center
●
button to enter the submenu, and then press the
●
button again to allow the value to be changed. Press
