Withstands Harsh Environments

Rain, snow, fire suppression spray and dust are no problem for these radios manufactured to strict IP ratings. The VX-920 series meets international waterproofing standard IP57 where water does not harm the radio when submersed to a depth of 1 metre for up to 30 minutes.

Never Miss An Important Call

Includes DTMF paging and unmatched flexibility in scanning features that are designed to optimise operation in a wide variety of environments. In addition to basic scan, you also get Priority, Dual Watch, Follow-me, Follow-me Dual Watch and Talk Around scanning with a programmable home channel function built-in.

When Safety Counts – Never Be Alone

When help is needed, the VX-920 Series has Emergency notification that will switch to a designated channel and send an emergency alert. The radios also include Remote Listen which turns the radio on remotely if needed to check out what is happening near the radio.

Loud Audio For Noisy Environments

With 700 mW audio output, be assured of hearing critical information you need.

Exclusive Auto-Range Transpond 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 for more than 2 minutes, your radio senses no signal has been received and beeps to alert you.The base station can then alert the field unit to move back in range. A great solution to keep your workers coordinated.
