Good listening baby. No interference. Sonne if the parent unit is unloaded. Live pilot can turn the parent unit and the pilot light can be allowed without the need to leave the parent unit light (useful at midnight when we want to see her baby without having to turn more violent lights) . The only downside, but in my opinion largely offsets the discount on the price, it is the UK taken. However the seller has shipped us together 2 EN adapters without adding tariff! It's just a bit as binding adapters are difficult to connect (security requires us to really force) but in general the base remains fixed in the room, this is not very serious.
