Water, dust, temperature extremes, shock and vibration are no problem for these radios manufactured to rugged Military Standards specifications. The VX-820 Series also 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.
Get the ultimate signaling performance with a choice of multiple 2-tone encode and decode or 5-tone signaling to support the most advanced communications needs from individual to fleet operations. The front panel also includes a 7-colour LED with a variable flash pattern for custom incoming call alerts.
When help is needed, the VX-820 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.
With 700 mW audio output, be assured of hearing critical information you need in most situations.
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 co-ordinated.
