When Safety CountsAs with all Vertex Standard portable radios, the VX-350 Series includes both Emergency and Lone Worker alerts to help monitor user safety: Emergency alert can be programmed to instantly notify help with a press of a button. Lone Worker is a built-in timer that requires the user to reset at a predetermined interval. If not reset, the radio automatically switches to Emergency mode to alert help. An ideal solution for supervisors to monitor the safety status of radio users working alone. Prevent Unauthorized UseIf lost or stolen, the VX-350 Series can be quickly disabled remotely by sending a Stun command for temporary disabling or Kill command to permanently disable the radio (then needs to be returned and re-programmed before using again). Auto-Range Transpond System (ARTS)Always know your connection status. Only Vertex Standard radios are designed to inform you when you and another ARTS-equipped radio are within communication range. If out of range, your radio senses no signal has been received and beeps to alert you. A great solution to keep your workers coordinated. For more information, download fact sheet.
