This audio block adaptor allows you to use an earpiece which has a Motorola 2 pin plug with a GP320, GP340, GP360, GP380, GP640 and GP680 walkie talkie. The adaptor is secured to the radio side with a single screw fixing and incorporates a 3.5mm/2.5mm socket to fit a standard moulded plug.
Be sure to turn the radio off before attaching the adaptor and plugging the earpiece into the adaptor. The adaptor only needs to be finger tight, do not over tighten.
