PLEASE NOTE:
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
interference such as to greatly reduce the range of the transmitter. In such an instance please contact your
Dominator® dealer for an alternative frequency replacement kit. As this is not a warrantable situation but an
environmental issue charges may apply for the change-over.
