Radio Programming

FACT: Radio programming plays an important part to ensure that your investment fits perfectly into your business and must be completed on every radio before it is functional. Radios do not come programmed from the manufacture so selecting basic or advance programming is required when ordering radios.

Select basic or advanced programming in the shopping cart or give us call if you have more questions.

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.
