Query: Complete disappointment

I bought this product after reading the reviews here, and I was VERY disappointed. We use a fan in our baby's room, and our last monitor had no problem transmitting all sounds! We dropped out last monitor one time too many, and bought this one. With the fan on, you can hear NOTHING coming out of the monitor except occasional loud bursts of static. Without the fan on, it works OK, but that doesn't really help us. Very disappointed.
