Sony BabyCall Nursery Monitor NTM-910 900 MHz Review

I purchased this monitor because it was priced well.  The problem I have with the monitor is that it makes a clicking noise if you turn the monitor up to hear the babies noises.  The clicking noise is very annoying and at night when I am trying to sleep it keeps me up.  Because I had purchased it at Babies R Us and did not have my receipt I could not return or exchange.  I did email Sony about the problem, but it was difficult to explain the problem through an email.  I have had the monitor for over a year and still use it for my toddler.  I am expecting my second child in a few months and have register for a different monitor.  This time, I want a monitor that has a visual screen of the baby sleeping and noise detector.  Don't assume that it is a good product because it says Sony.  The Sony Babycall  NTM-910 was a bad choice.  By the way, if it is close to a cell phone, it makes a loud screaming noise if you are getting an incoming call.
