Description
IMPRES Windporting Remote Speaker Microphone for Listed APX and SRX Radios
The Motorola PMMN4083AL DELTA-T is a wired remote speaker microphone with IMPRES audio technology and Windporting. It places the speaker, microphone and push-to-talk control within reach while your compatible radio remains secured on your belt or equipment.
Windporting helps reduce wind-related microphone noise and water-related obstruction at the microphone port. It is not a guarantee that speech will remain clear in every noise or weather condition. The microphone still requires push-to-talk operation; clipping it to clothing does not make transmission hands-free.

Frequently Asked Questions
Which radios are listed as compatible?
The existing listing identifies APX2000, APX3000, APX5000, APX6000, APX8000, APX8000XE and SRX2200. Confirm the exact radio version and application before purchase.
Is this a wireless or Bluetooth microphone?
No. PMMN4083AL is a wired remote speaker microphone connected to a compatible radio.
Does clipping the microphone to clothing provide hands-free transmission?
No. It provides convenient speaker, microphone and push-to-talk access while the radio stays secured. Do not assume VOX or automatic transmission is included.
What does Windporting do?
Windporting helps reduce wind-related microphone noise and water obstruction at the microphone port. It should not be treated as a guarantee of noise cancellation in every environment.
How deep can the microphone be submerged?
The listing identifies IP68 and previously stated 6 feet for 2 hours, but that exact limit has not been independently confirmed for this part. Check the applicable manufacturer instructions for depth, duration, connector installation and maintenance conditions before immersion.
Does this replace PMMN4083 or PMMN4083A?
The existing listing describes PMMN4083AL as an updated version of those part references. Confirm the exact replacement requirements for your radio and operating environment rather than assuming every revision is interchangeable.
Is the radio included?
No. This purchase is for the remote speaker microphone. A compatible radio is required separately.
