Alert is an active-volume hearing protector that listens to the surroundings. The unit has a built-in FM radio receiver that can be connected to a 3.5 mm input for telephone or comms radio for complete two way communication.

Alert has an advanced FM radio as standard. The sound is reproduced in stereo with a bass that does the music justice. The short, flexible antenna provides excellent reception with no annoying interference, even in harsh conditions. The sound level of the radio never exceeds 82 dB(A).

If the reception signal is too weak, the electronics automatically switch to mono for the best possible quality and comprehension, without interrupting the sound.

In accordance with PPE directive 89/686/EEC, and applicable sections of European Standard EN 352.
