The Motorola PMMN4148A RM110 is a compact and durable remote speaker microphone designed for the Motorola MOTOTRBO R2 two-way radio.
Its loud 101-phon speaker provides clear incoming audio, while the built-in microphone and large push-to-talk button allow users to communicate without removing the radio from their belt or carrying position.
Motorola’s windporting technology helps reduce interference caused by wind and outdoor weather conditions, making the microphone suitable for construction sites, security patrols, events, agriculture and other demanding working environments.
A built-in 3.5mm audio socket allows a compatible receive-only earpiece to be connected for more discreet listening.
