What Is the PMMN4040 Used For?

A remote speaker microphone places transmit control and received audio within reach while the radio stays in its carrying position. It suits personnel who communicate frequently while walking, inspecting equipment, directing activities, or performing other field tasks.

Windporting helps reduce wind-related microphone interference. Because the PMMN4040 has no earpiece connector, volume control, or programmable buttons, it’s a simple choice for users who want a compact mic without extra features.

Compatible Motorola Radios

The PMMN4040 is listed for these radios:

Confirm your exact radio model and the microphone revision before ordering. For APX 2000 and APX 4000 applications, see Motorola’s APX 1000/2000/4000 accessory approval documentation. Browse our Motorola APX radios, batteries, and accessories for related parts.

Restrictions and Requirements

• Check the exact radio and microphone revision. PMMN4040 is the base product number. Approval documents may specify suffixes such as A, AL, or BL.
• An IP rating is not hazardous-location certification. Where intrinsic safety or another hazardous-location approval is required, the radio, battery, microphone revision, and attached accessories must match the applicable approved combination. This applies to the IS radio models in the table above.
• A listen-only earpiece can’t plug directly into this microphone. Choose a mic with an audio jack if you need private listening.
• Windporting is not industrial noise cancellation. Pick an accessory based on the noise conditions and functions you need.

How to Use the PMMN4040

Turn the radio off before connecting or disconnecting the microphone. Attach and secure the connector according to the radio’s instructions, then position the swivel clip and cable so the mic is accessible without creating a snagging hazard.

Turn the radio on and check received audio. Press and hold the PTT button while speaking, then release it to listen. Test the setup before work, and inspect the cable, connector, and housing periodically.

Is this an original Motorola speaker microphone?

Yes. This listing is for the Motorola Original PMMN4040, not the Command Tac replacement.

Is the PMMN4040 waterproof?

Motorola specifies IP57 protection and describes testing at one meter for 30 minutes. Damage, worn seals, or improper installation can affect protection. See Motorola’s product page.

Does it have an earpiece jack?

No. The original PMMN4040 has no audio-accessory jack. For a mic with one, see the Command Tac CTM-4040WP.

Is the PMMN4040 an IMPRES microphone?

Motorola doesn’t identify this model as an IMPRES microphone. The PMMN4046 and PMMN4050 are alternatives to compare when you need IMPRES audio.

Is it intrinsically safe?

Certain revisions appear in Motorola approval documentation for specified systems. Confirm the exact microphone label and the complete approved radio configuration before hazardous-location use.

Is PMMN4040 the same as PMMN4040A?

PMMN4040 is the base part number. PMMN4040A and suffixes like AL identify product revisions, so confirm the revision your radio requires.
