Performance and Processing Power
Clear audio is essential in high-noise zones, and the IS-RSM3A.1 delivers with a loud front-facing speaker rated at over 103 dB and a noise-cancelling omni-directional microphone. This ensures messages are heard and captured even in challenging environments like refineries and chemical plants.
Button Functions and Input
The microphone features an intuitive button layout, including programmable Push-to-Talk (PTT), SOS, volume, and multifunction keys. Most buttons can be reassigned through the i.safe Button App to support custom workflows, alerts, or emergency communication features.
Connectivity and Interface
As a wired unit, the IS-RSM3A.1 connects directly to supported i.safe MOBILE devices via a 16-pin ISM interface or 8-pin circular connector, depending on the variant. This guarantees secure, stable operation without the need for Bluetooth pairing or internal batteries.
