2.1.3Entering a Password

To change the value of a parameter in a menu, you must first enter the password for that menu. The User, Service and Advanced menus each has a unique password to prevent unauthorized changes.

The User menu password is 1490; the Service menu password is 5010.

NOTE

Entering the Service menu password permits access to both the User and Service menus.

To enter a password:

1.Navigate to the menu that contains the parameter to be changed.

2.Select Password in the submenu by pressing the Enter key

3.Press the Enter key to move your cursor to the right side of the screen to select the question marks.

4.Use the arrow keys to enter the numeral for the password’s first digit (the up arrow key moves from 1 to the next digit).

5.Use the right arrow key to move to the next question mark and repeat Step 4 to enter all digits in the password.

6.After entering the password, press enter.

If the password is correct, the Actual Level shown to the right of Password will change from 0 to 1 or 2. The menu will remain locked if the password was incorrect.

NOTE

Returning to the Status menu will require re-entering a password to make changes.
