Abstract
Abstract A wireless-accessible module which provides first and second wireless-transmitter control signals, such that the first transmitter control signal can be activated automatically, in response to incoming wireless signals, but the second transmitter control signal can only be activated by manual input or direct command. Preferably the two control signal outputs are used to select the power level of transmission on a single predetermined frequency; but alternatively these outputs may be used to control two different RF transmitters and/or two different antennas.
