You
may wish to change this parameter on certain occasions such as Thanksgiving
or other weekday holidays when no one will be in the office. Instead
of automatically changing to day mode in the morning, you want it to stay in
night ringing mode. If you are in AUTO switching mode it changes to
Day mode at its normal time. You wish it to stay in night mode because
no one is in the office. The way to do this is change the system
parameter, and put the system in night mode. It will stay there until
it is manually put in day mode. When you are back in your normal
operating hours, change the program back to AUTO.
When in AUTO the system will switch
automatically as programmed. When in MANUAL, the system will only switch
manually.
