If wireless microphones or other radio equipment operating on unlicensed bands are in use in the neighborhood of the setup, check to see that the radio frequencies they use do not conflict with the Wireless Response System. The TX and RX numbers on the back of the keypads list the frequencies they use to transmit and receive data. Many wireless microphones can be adjusted to use different frequencies; however, the Wireless Response System cannot.

Move the interface away from short range interface sources such as LCD overhead panels, laptop and desktop computers, and video projectors.

Investigate the presence of other potential sources of heavy RF interference, including heavy electric motors such as those used in freight elevators and dimmers for lighting systems. RF interference is typically indicated by response data spontaneously appearing on the diagnostic map without any keys having been pressed.
