The CMP1/750 is attached with a revolving clip and allows the radio user to carry the radio on their belt and have the facility to both make and receive calls without removing their radio. This keeps the radio safe and ensures that calls are not missed, especially in noisy environments. The CMP1/750 has a socket (3.5mm mono) to allow an optional earpiece (EHP9) for discreet reception of calls. This accessory is designed for light to medium duty applications, so to ensure maximum life span it should be personally allocated to users.
