1. Press the blue Super key or the programmed Super key screen button. 
   The 5320, 5330, 5340, and 5360 will need the Superkey to be programmed as a screen button, please see How do I program my buttons?
2. You should see the first option, Phonebook.

8. You should now see a message on your screen indicating the service you're in.
9. You can add a Night Service Indicator by either programming a key through your phone (depending on model) or through your system. This will let you know when the system is Night service by illuminating the key.
