The Avantek SMW88-6070 is a wireless doorbell system that pairs a plug-in AC receiver with a battery-operated transmitter, communicating via custom-encoded 433.92 MHz transmission over distances up to 400 m. The receiver offers 52 selectable melodies with adjustable volume output and operates from standard AC mains (110–260 V). The transmitter uses a CR2032 3 V lithium button cell rated for up to 3 years of operation at 10–15 daily actuations and features IP55 dust and water resistance for outdoor mounting. Built-in stereo speaker delivers sound pressure levels up to 115 dB. Operating temperature range spans −20 °C to 60 °C. Pairing is manual; custom encoding prevents interference from external RF sources. The receiver draws less than 0.25 W in standby mode and incorporates an American Power Integrations power chip rated at 250 mA maximum output.
