  • Page 65: Making An Sos Call

    Making an SOS call In an emergency you can summon help by sending an ‘SOS call’ to a predetermined location, usually your dispatcher. The radio then cycles between receive and transmit, so that the called party can hear any activity near the radio. When the radio is in SOS cycling mode, the transmitted audio is always from the radio’s internal microphone, regardless of whether an external speaker-microphone is installed.

  • Page 66: Using The Lone Worker Emergency Features

    Using the lone worker emergency features Your radio may be programmed with ‘lone worker’ emergency features, designed for people who work alone in potentially hazardous areas. If you become incapacitated, the radio automatically sends a distress call to alert other users to your situation.
