I'm using the DX2000 Advanced Security Function (/AS1 option) model. When I log in, the message, "Error E006 Incorrect input character string" appears.I'm entering the correct user name, so what should I do?

Using the following procedure, reconfirm the registered system administrator information.

1. Enter “root” for the user name, and press DISP/ENTER without entering a password. An error message will appear, followed by a window for entering the password again.
2. Enter the root password, and press DISP/ENTER. You can log in as the root user. The initial root user password is root123.
3. Press MENU (to switch to setting mode), hold down FUNC for 3 s (to switch to basic setting mode), and select the Environment tab > Security, Media save (Security,Media save, Batch on the DX2000). Next, turn Password management OFF.
4. Press MENU (to switch to setting mode), hold down FUNC for 3 s (to switch to basic setting mode), and select the Menu tab > Login > Admin settings. Finally, reconfirm the registered system administrator information. We recommend that you register multiple system administrators.
