4. If a window contains several pages, click on the tab at the top to open the page. The font weight of the characters on the tab of the visible page is bold.

5. Any changes you make will not take eect until you click on "Apply". Changes will be lost if you open another page of the web interface or if you close the web interface without ﬁrst clicking on "Apply".

6. Whenever you click on "Apply", the "Save" button will appear at the top of the page. Click on "Save" to save the changes permanently. Changes that have not been saved will be lost if and when the phone loses power or is disconnected from its power source.

Admin mode and user mode

Snom phones can be operated in administrator or user mode. In administrator mode, all settings are accessible and can be modiﬁed; in user mode, a number of settings are not accessible. The factory default is administrator mode; however, if your phone is administered centrally, user mode may be the rule. Please check with your administrator.

When the phone is running in user mode, the administrator password is required to revert to administrator mode. The default administrator password is 0000 (4 x zero). We recommend that you change the password.

Note: Do not forget to write the new password down and store it in a safe place; without it, a TFTP reset to factory values is necessary to return the phone to administrator mode.

In admin mode In user mode

To access pages not available in user mode, enter the administrator password to return the phone and its WUI to administrator mode.
