- Cable Care: Avoid excessive pulling, twisting, or sharp bending of the coiled cord to prevent internal wire damage.
- Storage: Store the RSM in a clean, dry environment when not in use.
8. Troubleshooting
If you experience issues with your PMMN4084A Remote Speaker Microphone, consider the following:

- Transmission Issues: Verify the RSM connector is secure. Ensure the PTT button is fully depressed when speaking. Check the radio's battery level.
- Intermittent Connection: Re-seat the RSM connector firmly into the radio's accessory port. Inspect the cable for any visible damage.
