Some areas may be prone to excessive radio interference brought on by devices such as cordless telephones,
wireless stereo headphones and baby monitors. It is possible that these devices could cause a degree of

Automatic Technology dealer for an alternative frequency replacement kit. As this is not a warrantable situation
but an environmental issue. Charges may apply for the changeover.
