Description
Replacement Volume Control Dial for Professional Portable Radios
Restore Precise Audio Control
Reestablish immediate and responsive volume adjustment on your fleet's hand-held transceivers.
The Motorola 3680529Z01 Replacement Volume Knob is a genuine original equipment manufacturer (OEM) component designed to maintain factory-spec performance on commercial portable two-way radios. Molded from an impact-resistant industrial black polymer, this heavy-duty dial directly replaces lost, cracked, or degraded volume control interfaces, ensuring clear tactile feedback when turning the radio power switch or adjusting audio levels in the field.
Engineered for public safety personnel, construction foremen, and logistics coordinators, this replacement part prevents common fleet maintenance downtime. Over extended deployments, original dials are subjected to continuous friction and environmental stress, making a secure physical control interface vital for uninterrupted operations. Replacing a worn knob ensures the sensitive internal electronic potentiometer stem remains protected from dust ingress, impact shock, and structural degradation.

Frequently Asked Questions
Does this product include the internal electronic control switch?
No. This item consists of the external molded plastic volume knob dial only. It does not include the internal metal potentiometer shaft, electrical wiring, or internal radio circuit boards.
Can this component also be used to replace the channel selector knob?
No. The top channel selection dial and the audio volume control knob feature entirely distinct physical internal dimensions and height markings. This item is explicitly molded to fit the half-round volume potentiometer stem.
How is this volume knob installed on a portable radio?
Installation is completely tool-less. Align the internal flat edge of the replacement knob with the flat side of your radio's metal volume control stem, then press downward firmly until it locks securely into place.
