Extended Signaling and Security

Both radios provide a full range of signaling capabilities including 2-tone, 5-tone and MDC-1200® encode/decode for selective calling.

Private communication is supported by built-in voice inversion encryption. And, if a radio is ever lost or stolen, 5-tone remote stun/kill/revive can be activated to ensure messages are only heard by those intended.

Enhanced Audio Performance

Features Channel Annoucement which loudly speaks the current channel description to simplify changing channels when focused on other tasks simultaneously.

Includes voice activation (VOX) that enables users to transmit voice without pressing the Push to Talk button on the microphone. Enables hands-free operation for convenience.

In noisy environments, activate the Clear Voice function to enhance audio transmit to ensure your message is heard. And, to ensure a radio is not accidentally turned down too low, a minimum volume limit can be programmed by your Dealer.

Whisper mode is also included to augment audio transmit when talking quietly is necessary for discreet communications.

Record and store up to 120 seconds for keeping an audible record of important messages using the optional DVS-8 Voice Storage unit.

When Safety Counts

As with all Vertex Standard mobile radios, the VX-4500/4600 Series includes Emergency alert for enhanced driver safety.

Operators can activate the Lone Worker function when leaving equipment or a vehicle temporarily. If a problem arises while away, the radio switches to Emergency mode to alert help.

When constant contact is required at all times, always know your connection status with Auto-Range Transpond System (ARTS™). Only Vertex Standard radios are designed to inform you when you and another ARTS™-equipped radio are within communication range. If out of range, your radio senses no signal has been received and beeps to alert you.

Large Group Communications Made Easy

The VX-4600 Series has 512-channel capacity and 32 groups to easily manage a variety of calls at the most complex job site. For smaller operations, the VX-4500 features 8 channels.
