The Motorola Transmit Inhibit License Key (HKVN4383A) activates the Transmit Inhibit feature in DP3xx1/e, DP4x0x/e, DP4x01 Ex, DP4x01 Ex Ma, SL40x0/e, and DM4x0x/e radios. This feature allows users to place the radio in a mode where it will not transmit any long-range RF energy. Designed for environments where transmission must be restricted, this feature ensures compliance with safety regulations and minimises interference in sensitive areas. Easy to activate and integrate, the license key provides organisations with enhanced control over their communication devices.
