This IMPRES remote speaker microphone conveniently clips to your shirt pocket or lapel and enables easy communication without having to remove the radio from your belt. Innovative audio technology enables you to hear and be heard over crowd noise, machinery and blaring sirens. IMPRES technology allows the radio to read the audio characteristics stored in the specific MSI audio accessory and configure its audio line up to provide the highest quality transmit and receive experience possible. The water and windshielding feature is specifically designed for windy, outdoor environments and dramatically reduces the noise caused by howling winds and harsh weather. Volume control toggle increases/decreases RSM speaker volume from radio maximum to radio minimum independent of ION volume setting. 2 programmable buttons may be configured for radio functions independent of radio programmable buttons. Also features an orange emergency button.
