Query: This phone does not interfere with wireless network

After spending a lot of time researching, we purchased this cordless product. It looks cool, is easy to set up, and intuitive to navigate. We did not have to use the manual at all, although a very thorough booklet is included. The sound quality is excellent, and very important to us: the Vtech has not interfered with our wireless network.
