Query: A warning

I too bought the Sony Baby Call based on reviews, because my Graaco monitor had such a poor battery life and was loud. The good news about Sony is that the battery lasts a good long time. The bad news (and there is a lot) is that the range is very poor. I can't get the mail from the box without the range alarm going off. Worse still is the sounds it makes. The monitoring sound is very quiet, but it often emits a random beeping noise or a sudden loud static clatter which can wake me up. Maybe because our small bedroom has a fair share of electronics in it (TV/VCR, phone & clock radio) but it's constantly burbling and beeping, even when we try placing it at different places in the room. Last night the static woke up our child, it was so loud. I'm back on the baby monitor search.
