The clear audio acoustic coil tube features a quick disconnect, and a black tube is available as an option. It can be adjusted for left or right ear use and includes an eartip. Compatible with a wide range of EF Johnson and Motorola radio models.

Using this earpiece is easy. First, connect it to your Motorola or EF Johnson radio. If you've got the Signal Quick - Disconnect earpiece, make sure you attach the separate Quick - Disconnect adapter. Clip the PTT button to your clothing for easy access. You can adjust the earpiece to fit either your left or right ear. When it comes to the audio tube, you can choose the clear one or the optional black tube. For maintenance, keep the earpiece clean by gently wiping it with a soft cloth. Avoid exposing it to extreme heat or moisture. When not in use, store it in a dry place. And always make sure the connections are secure to ensure clear audio.
