Query: Anyone Else Have Trouble with 2.4 Ghz Phone?

This monitor seemed to work well the one night I used it...but the very next day my 2.4 GHz cordless phone showed OUT OF RANGE on the handset-- meaning it could no longer find the cordless phone station and I could no longer make or receive calls. I unplugged both the parent and child units for the monitor, but my phone is still not working. The phone is downstairs in the kitchen and both units were upstairs in the bedrooms. My phone has never shown OUT OF RANGE in the 12+ months that I have had it. I don't know if this is a coincidence, but I am concerned that the first night's use of this 2.4 GHz monitor coincided with my 2.4 GHz phone no longer working.
