I put in batteries and tested it; seems to work. Lights up and makes sound when plugged in with the included power supply as well. The Realistic TRC-219 is a vintage 3-channel handheld CB Citizens Band radio (walkie-talkie) famously used by characters in the Netflix series Stranger Things. Released by Radio Shack around 1985, Features super long telescoping antenna! Like 3 feet! Excellent physical condition, strap is immaculate. There was some corrosion on the inside I cleaned off - as pictured. Uses 10 'AA' Batteries, NOT included. Power supply pictured included. For parts/As is as I I cannot speak to if it functions as intended I don’t have a 2nd radio.
