Easy to Carry

Highly portable, the VX-231 is a compact and lightweight radio that gives you the consistent performance and reach you need for your job.

Battery-Power Options for Every Budget

The VX-231 is designed to use powerful Li-Ion and Ni-MH battery technology with three options. With the battery saver activated, the Vertex Standard Portable two-way radio, VX-231, can provide between 9 and 16.5 hours of operation.

Safety Always Comes First

Like all Vertex Standard portable radios, the VX-231 includes both Emergency and Lone Worker Alert Functions to help monitor user safety. You may programme the Emergency Alert to notify for help instantly with the press of a button. Alternatively, use the Lone Worker function to allow supervisors to monitor the safety status of radio users working alone in isolated areas.

More Scanning Options

While many radios provide only one or two scanning options, the VX-231 walkie talkie offers 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™)

Like all other Vertex Standard radios, the VX-350 Series is designed to inform you when another ARTS™-equipped station is within your communication range. If you go out of range, your handheld two-way radio will beep to alert you. It’s a great solution to keep your workers coordinated.
