I stopped having my dsc alarm PC5010 monitored. Can I use the audible only? I keep getting a trouble, clock problem and it won't let me set it.

*6 and you code should let you change time.
Hit *2, and tell what lights are on.
You need to be able to get into installer mode by hitting *8Code , 2 led's should start flashing upon entering correct code, to eleminate telephone line monitoring and you also need to disable communications, I believe locations 015, and 380.
