"Home."Happiness is using the red "Block" button and not having to worry about running out of blocked-call-number memory

Opted for the new model because of expanded number memory and lighted screen

Now it's 1000 number memory with a nice Back-Lite display

However, when I later removed and re-inserted the power plug from the rear of the unit (simulating a power outage to test the unit’s non-volatile memory) ... the caller ID issue recurred

My Call Blocker Plus worked very well but the memory was too limited
