The System Programming Feature tab and its button functions are only for the first extension in the system. These features are linked to the usage of the System Password as they affect the operation of the phone system for all users and trunks.

Night Service: Action Data = None.
A button set to this function allows the user to switch night service on or off. The System Password, if set, is required to use this feature. When night service is on, use and behavior of VMS on some trunks may change depending on the trunk configuration. Also when night service is on, users in the night service group must first use the System Password to make outgoing external calls other than emergency calls. If the user has this feature enabled, removing this button will turn the feature off.

Wake Up Service: Action Data = None, Software level = 6.1
It allows the user to set an alarm call to occur another extension in the next 24-hours. When the alarm occurs, if the call is answered the targeted user will hear music on hold if available, otherwise they hear repeated tones. If the call is not answered another attempt is made 5 minutes later, however only 2 attempts are made. Only one alarm can be set against each user at any time. Setting another alarm will override any existing alarm.

When selected, this option removes all programming from the button.
