I had lots of interference to the point where you cannot understand whats being said. I tried it on seperate plug sockets, even in the same room but with the same result.

We were unable to get this item to work properly. The best we managed to get out of it was a creaky squeek or an whiny moan.

Customer Questions about 3 Channel Wireless Intercom

Q: Would the units pick up "electrical noise interference" from items such as a fridge's compressor connected to the ring main circuit?

Pete - 11/03/2006

Maplin says: Yes this can be a problem with this type of system if several electrical items are placed on the same circuit (particularly items with a motor or compressor in them).

Q: How far does each base unit have to be? i.e how far can i place each base unit from each other in order to still transmit a very good clear signal and sound?

Roger Taylor - 22/07/2007

Maplin says: distance is not an issue as long as all units are on the same ring main.
