work connected circuit breaker is required, proceed by using the On/Off pushbutton to turn the programmer on.

Notice: Keep in mind that a change in the baud rate and/or address is password protected. Entry of a valid password will be required before any changes are accepted. If the programmer was already turned on, and a valid password was initially entered as described in paragraph 3-4 Method 1, entry of a password will not be required again and the baud rate and/or address changes will be saved. If a valid password was not initially entered, the display will require the entry of a valid password before any changes can be saved (Figure 3-8). Follow the steps outlined in paragraph 3-4 Method 2 to enter a valid password.

Step 2: Once the main menu is displayed, use the Select pushbutton to enter Select Address (SA) which is active as indicated by the blinking cursor. This network display provides a means for selecting the three digit address of the circuit breaker of interest within the network (Figure 3-16). The blinking cursor indicates which of the three digits is active and able to be changed.

Step 3: Use the Up or Down pushbuttons to change the active digit. Use the Right-Arrowor Left- Arrow pushbuttons to move the cursor from one digit to another.
