Easy to Carry

A radio that won’t get in the way, the VX-231 is compact and lightweight without sacrificing the performance and reach needed on the job.

Battery Power Options For Every Budget

Designed to use powerful Li-Ion and Ni-MH battery technology with three options providing up to 9 hours to 16.5 hours of operation with the battery saver enabled.

Safety Features Not Sacrificed

As with all Vertex Standard portable radios, the VX-231 includes both Emergency and Lone Worker alert functions to help monitor user safety. The Emergency alert can be programmed to instantly notify help with a press of a button. The Lone Worker function allows supervisors to monitor the safety status of radio users working alone in isolated areas.

More Scanning Options

While many radios provide one or two scanning options, the VX-231 radio has four scanning options for greater convenience and flexibility in the way you need your radios to perform. Options include: Priority, Dual Watch, Follow Me and Talk Around scan.

Exclusive Auto-Range Transponding System - ARTS™

Only Vertex Standard radios are designed to inform you when you and another ARTS™-equipped station 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.
