note 1st pic a bit of the mic cord has split on outer casing which can have tape job to repair ; i think these ;are the intrinsically safe units ; i got them from a friend who was a contractor on oil rigs ; and these where all new when i got them; now gathering dust ; i did have an issue and sent the charging dock to icom who put new fuses in all 6 pods so i would advise using a surge protector before the plug ; so i charger dock 2 m87 with mics shown with green light for charged ; i will put in extra battery but cant vouch for if working
