Product Description


Ensure Your Safety With Vertex VX-451

Vertex VX-451

The Vertex VX-451 is a portable analog radio that features 3 custom-programmable keys and numerous safety features. Like all Vertex Standard radios, the VX-451 includes built-in safety features including Emergency and Lone Worker alerts. The Emergency feature makes calling for help easy by just pressing a button. When the button is pressed, the radio will switch to a specific channel that calls for help. The Lone Worker feature is a timer which requires you to reset within a specific time interval. If it is not reset in that time period, the radio will switch automatically to Emergency mode and send out a help alert. Another incredible safety feature is the Man Down function (with DVS-9 unit), which uses a 3-axis sensor to monitor if a worker falls and then can alert for help. The Vertex VX-451 is definitely there for you in all situations.
