The OpenStage M3 DECT handsets are a family of mobile devices designed for harsh environments where they are exposed to moisture, dirt, shocks, dust, or high ambient noise. With an IP65 protection rating, these handsets are perfectly suited for such conditions. Additionally, variants with different emergency call options and those that can be used in explosive environments are available. Although the OpenStage M3 handsets are designed for these environments, they impress with their high-quality build and a large 1.8" TFT color display featuring modern navigation. The OpenStage M3 handsets are the successors to the Gigaset M2 professional handsets.
