Compatible Microphones

The 3075336B07 is designed primarily for:

• Motorola RMN5052 Standard Compact Microphone

• Motorola RMN5052A Standard Compact Microphone

These microphones are commonly used with select MOTOTRBO XPR, DM, DGM and XiR mobile radios.

Compatibility should be determined by the complete microphone model rather than the connected radio alone.

Common Replacement Reasons

The original microphone cable may need replacement when it develops:

• Cracked or damaged insulation

• Intermittent transmit audio

• Intermittent push-to-talk operation

• Loose or damaged connectors

• Excessive stretching

• Internal conductor failure

• Damage near the microphone strain relief

Replacing the cable will not correct faults caused by the microphone housing, push-to-talk switch, internal circuit board or connected radio.

Installation Information

The 3075336B07 is an internal replacement component and requires the compatible microphone to be opened during installation.

Professional installation is recommended to:

• Prevent damage to the microphone housing

• Ensure correct internal connections

• Preserve proper cable strain relief

• Verify push-to-talk and audio operation

• Confirm reliable communication after repair

3075336B07 vs. 3075336B10

The 3075336B07 is the replacement cable for compatible compact microphones such as the RMN5052A.

The 3075336B10 is designed for select heavy-duty and keypad microphones, including the RMN5053, RMN5065 and RMN5127. These cables should not be treated as interchangeable.

Important Product Distinction

This is a replacement microphone cord. It is not a microphone extension cable and does not include the microphone housing, push-to-talk switch or internal audio components.
