Setting Parameters
30 General Programming
30.1 Modification of parameters: Exit menus
When you exit any of the menus the transmitter will check whether parameters have been
modified. If yes you will be prompted whether these parameters are to be saved.

See sect. “30.2 Save Parameters”.
Options and effects when you exit the menu:
• >Yes<: the modification will be accepted and saved.
• >No<: the modification will be rejected and the menu is exited.
• >Cancel<: You are exiting the prompt. Parameters remain to be modified but will not
become effective and will not be saved, however.
30.2 Save Parameters
As a principle modified parameters will not become effective before they have been saved.
If you wish to accept and to save parameters you need to enter a valid password.
Default setting:
2718
The
service key
in this area indicates that the password has been entered within the last six
hours and that any further
parameter changes
can be saved
without
having to re-enter the
password
. The six-hour period begins once the password is entered and ends automatically.
This period and thus unintentional parameters changes without password entry can be deli-
berately aborted. To do this, select the > Service level< under >System< / >Service<.
Do not
make an entry
in the following prompt for the password, but confirm the empty, untouched
field with the right >Enter< button. The transmitter leaves mode with the parameterization
without entering a password.
If a number is displayed next to the service key, the transmitter is in service mode. This is
usually the case when a NIVUS service technician has access to the transmitter.
30.3 Change Password

See also Sect. “34.5.2 Change (System) Password”.
You can change the default password at any time. However, keep in mind that a modified
password will secure any modifications of the transmitter settings. Here, the password length
is limited to a maximum of ten characters.

Procedure to change the password:
1. Open the >System< menu.
2. Select >Service< submenu.
3. Activate the field >Change Password<.
4. Use the number field to enter the current password.
5. Then enter the new password (ten characters max.).
The transmitter will accept the new password securing all transmitter settings.
