This transmitter is available in the same UHF frequency ranges and is
equipped with the same frequency bank system with factory-preset
frequencies. An advantage of the factory-preset frequencies is that
• a transmission system is ready for immediate use after switch-on,
• several transmission systems can be operated simultaneously on the
preset frequencies without causing intermodulation interference.
