We have a Panasonic TDA 50 system (with a TVA 50 voicemail setup). Our system currently goes into NIGHT MODE automatically at 5:55pm each night (3:55pm on Sunday). I want to change that temporarily (for the next few weeks) to 3:55pm every day and 2:55pm on Sunday as we've reduced our hours due to the COVID19 crisis. How do I change that setting?

Thanks in advance if you can offer any assistance!

John
