Clear audio in noisy working environments

The IS-RSM3A.RG is designed to deliver reliable voice communication where background noise can make standard audio accessories difficult to use.

Its powerful loudspeaker provides audio output above 103 dB, helping users hear calls and alerts more clearly in noisy environments.

The remote speaker microphone uses omni-directional electret condenser microphones with noise-cancelling technology. This helps capture voice input clearly while reducing unwanted background noise during communication.

Designed for Push-to-Talk and lone worker applications

The IS-RSM3A.RG is well suited to Push-to-Talk over Cellular, Mission Critical Push-to-Talk and lone worker protection applications when used with compatible devices and software.

The device includes a left function key for PTT, a red function key for SOS-style applications, function keys for up and down control, and a circular function key. All keys, except volume up and down, can be assigned to a function via the Button App.

This gives organisations the flexibility to configure the remote speaker microphone around their own communication and safety workflows.

Rugged and easy to use

The IS-RSM3A.RG is designed for practical use in tough working environments.

It has an ergonomic design, is easy to operate even when wearing gloves, and weighs 205 g without the cable. The device is IP68 protected, MIL-STD-810H tested and usable from -20 °C to +55 °C.

The replaceable 2200 mAh battery supports reliable daily use, while the included desktop charger provides a convenient charging option.

Compatible device support

The IS-RSM3A.RG is specifically designed for selected devices in the IS54x.x and IS940.x series.

This makes it a useful addition for teams using compatible i.safe MOBILE smartphones or tablets for Push-to-Talk, lone worker support, site communication or operational workflows.
