Equipment: GE Healthcare - Voluson E10
Hi try this procedure (it is for a Voluson E6 &E8) but might be the same for yours.
Volusons have 2 passwords as far as I know, "SHE" and "Rudi".
If the system BIOS is incorrect.
5. Press the Utilities key on the control console.
6. In the “Utilities” menu touch the Setup button to invoke the setup desktop on the screen.
7. On the right side of the screen select Administration and then click the Service tab.
8. Enter the password « she » and click Accept.
