I heard a beep in my apartment and finally checked the large unit that is installed in my closet and there is a red light on that says
REPLACE BATTERY. What is this? I was never informed anything about a battery. What type of battery do I need...where do I get one...how do you install it? I have the verizon fios and I am lost with this
As I mentioned I never was told anything about a battery and therefore this came as a surprise to me. ANY assistance would be appreciated.
Thank you
