The wireless radio frequency output during communication in the RTR-500 and RTR-7 Series are about 10mW; about the same as a low power transceiver.
Output for the RTR-5 Series is just one-tenth of that or 1mW.
Hence no effect will occur on nearby devices or equipment.
Moreover, the devices are registered with the proper authority and comply with local regulations (FCC or CE); there should be no interference with communication of other nearby devices.
