System 9000 Grounded Microphone Hang-Up Clip for APX Mobile Radios

The Motorola HLN5391A is a System 9000 microphone hang-up clip designed to securely hold a compatible Motorola palm microphone inside a vehicle or control-station installation. It keeps the microphone organized, protected and readily accessible for radio users.

The clip includes a grounding connection used by compatible radio and microphone configurations to detect whether the microphone is on or off the hanger. Depending on radio programming, this can support functions such as monitor operation or hook-state detection.

This genuine Motorola replacement kit is ideal for new APX mobile-radio installations or replacing a missing, damaged or worn microphone hanger.
