Which a choice of multiple 2-tone Encode and Decode or 5-tone signalling, the Vertax Standard VX-821 is ready for even the most advanced communication needs. Plus there is a 7-colour LED on the front panel with a variable flash pattern for custom incoming call alerts.

The VX-821 has been designed to keep things safe. The VX-821 features emergency notifications where the transceiver will switch to a designated channel and send an emergency alert for help. There is also Remote Listen which turns transmit on remotely if needed, in order to check out what is happening near the radio. Plus the Lone Worker mode uses a built-in timer that requires the user to reset at a predetermined interval. If this is not reset, the VX-821 automatically switches to Emergency mode to alert help.
The Vertex Standard VX-821 features the exclusive Auto-Range Transpond System (ARTS) that informs the user whenever they are out of communication range with another ARTS-equipped station. If out of range for more than 2 minutes, the VX-821 senses no signal and beeps to alert the user. The base station can then alert the field unit to move back into range. This is a handy feature for keeping everyone coordinated.
