Extended Signalling and Security Capabilities

The VX-4600 series provides a full range of signalling capabilities including 2-tone, 5-tone and MDC 1200® encode/decode for selective calling. With the built-in voice inversion encryption, private communication is enhanced, ensuring messages could only be heard by those intended.

Enhanced Audio Performance

  • Channel Announcement function works to simplify your chore of switching from the current channel to other channels while task on hand.
  • Equipped with Voice Activation (VOX) to enable users to transmit voice without pressing the hands-free operation for convenience.
  • Suitable for noisy environment, where the Clear Voice function can be activated to ensure your message is heard.
  • Suitable for quiet environment, where the Whisper capability function can be activated to augment audio transmit, perfect for much needed discreet communications.
  • Equipped with the DVS-8 Voice Storage unit, which enables you to record and store up to 120 seconds of important messages.

Monitoring Worker Safety

The VX-4600 series, as with all the Vertex Standard radios, has three key features to ensure the safety of the user.
  • Built-in Emergency Alert
    Equipped with the built-in Emergency notification function, which will switch to a designated channel, send an emergency unit ID and transmit with a live microphone, an added benefit when working alone.
  • Lone Worker Alert
    Operators can activate this function when leaving equipment or a vehicle temporarily. If a problem arises while away, the radio switches to Emergency mode to alert help.
  • Vertex Standard’s exclusive Auto-Range Transpond System - ARTS™
    A function that keeps the user within communication range with other ARTS™- equipped radios, so constant contact is at its optimal.

Manageable System for Large Group Communications

The VX-4600 series with 512-channel capacity and 32 groups for easy operations at the most complex job.

Remote mount option

If there is limited space, this radio has the added benefit of a remote mounted faceplate. Mount the faceplate in the dashboard and the main radio elsewhere; concealed under a seat or behind the driver in the cab of a truck, with no impact to your communications. The optional remote mount kit comes complete with a five metre ribbon cable with waterproof connectors.
