When the cord is stressed the cable could tear or fray and expose the internal wiring. As a result, RSM’s that show failures will be replaced for up to 24 months after purchase.
The cord failure is shown in the image. The failure typically occurs at the RSM head or radio connector end or both, but can also occur in cable middle section.
Radio users who prefer to route the mic cord behind their back and stress the cable are more likely to experience the problem. Motorola recommends to dress the coil section so it
does not get caught on uniform accessories for optimal RSM service life.
Motorola Remote Speaker-Microphone Models Affected
Motorola is upgrading the cable jacket material in the near future. RSM’s with the new cable will include an “L” in the model suffix when shipped.
Below are the RSM’s identified in the Motorola Technical Notification (MTN):
APX 8000, APX 7000, APX 6000, APX 4000,
MOTOTRBO PCR XPR 3000 and XPR 7000 Series RSM’s
Only mics that show the failure will be replaced under the MTN warranty extension. Reference MTN-0070-19-NA and original factory order number when requesting replacements. They can be obtained by calling Motorola at 1-800-422-4210; prompt 1.
