Motorola PMMN4149A RM110 Remote Speaker Microphone – IP55, No 3.5mm Jack

The Motorola PMMN4149A RM110 Remote Speaker Microphone provides convenient shoulder-mounted audio and push-to-talk operation for compatible Motorola portable two-way radios, allowing users to communicate without repeatedly removing the radio from their belt or carrying position.

Designed with a compact and durable housing, the RM110 features Motorola Windporting technology to help maintain clear voice communications in windy and demanding work environments. Its loud, clear speaker makes incoming radio traffic easier to hear while the integrated microphone and push-to-talk (PTT) button provide convenient access to transmit communications.

The RM110 features an IP55-rated design, providing protection against dust and water exposure encountered during everyday professional use. A low-profile swivel clip on the back of the microphone allows it to be securely attached to a shirt, jacket, vest, or other convenient location while allowing comfortable positioning throughout the workday.

This version of the RM110 is designed without a 3.5 mm audio jack, making it a streamlined solution for users who do not require a secondary receive-only earpiece connected through the speaker microphone.

Ideal for construction, manufacturing, maintenance, utilities, security, property management, hospitality, transportation, and other professional applications, the PMMN4149A provides convenient access to radio communications while keeping the portable radio securely carried.
