The OpenStage M3 DECT handsets are a family of wireless devices designed to perform in harsh environments. The family comes with variants covering different alarm options and also use in potentially explosive environments where moisture, dirt, shocks or high ambient noises could compromise communication quality. With its device protection class of IP65 it suited perfectly for these scenarios. Although the OpenStage M3 family is designed for these environmental conditions, it looks exquisite with its large 1.8 TFT color display and with an up to date user interface. As well as great style, it offers optimum functionality, with excellent voice quality optimized for noisy environments, Bluetooth interface and its black/silver color. The OpenStage M3 handsets are the successors of the Gigaset M2 professional handsets.
