Important Notes

1. M1 vs M2 / M7 / M11 Interfaces

Modern MOTOTRBO XPR / DP radios mostly utilize M7 or M11 interfaces. An adapter (such as AP-M9-M1) is required to connect an M1 connector earpiece to these radios.
2. Distinction Between K Connector and M Connector

The M1 interface features a 2-segment 3.5 mm jack paired with a 2-segment 2.5 mm jack. The K connector uses a 3-segment 3.5 mm jack and a 3-segment 2.5 mm jack. These two connector types are not directly interchangeable.
3. Compatibility for Digital Radio Models

Select digital radios including the CP200D support the M1 interface; however, advanced radio functions may not operate fully when paired with this accessory.
